The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.

Severe murine lung immunopathology elicited by the pathogenic equine herpesvirus 1 strain RacL11 correlates with early production of macrophage inflammatory proteins 1alpha, 1beta, and 2 and tumor necrosis factor alpha. (1/85)

The CBA mouse model was used to investigate the immunopathology induced in the lung by the pathogenic equine herpesvirus 1 (EHV-1) strain RacL11 in comparison to infection with the attenuated vaccine candidate strain KyA. Intranasal infection with KyA resulted in almost no inflammatory infiltration in the lung. In contrast, infection with the pathogenic RacL11 strain induced a severe alveolar and interstitial inflammation, consisting primarily of lymphocytes, macrophages, and neutrophils. Infection with either EHV-1 strain resulted in the accumulation of similar numbers and ratios of CD4 and CD8 T lymphocytes in the lung and bronchoalveolar lavage (BAL) fluid. Further analysis of these T-cell populations revealed identical EHV-1-specific cytotoxic T-lymphocyte responses. RNase protection analysis of RNA isolated from the BAL fluid of RacL11-infected mice on day 3 postinfection revealed much higher levels of RNA specific for macrophage inflammatory protein 1alpha (MIP-1alpha), MIP-1beta, and MIP-2 than were observed for KyA-infected mice. Furthermore, significantly higher levels of transcripts specific for tumor necrosis factor alpha were induced on day 3 postinfection with RacL11 compared with KyA. These findings suggest that the early production of proinflammatory beta chemokines plays a major role in the severe, most often lethal, respiratory inflammatory response induced by the pathogenic EHV-1 strain RacL11.  (+info)

DNA vaccines encoding interleukin-8 and RANTES enhance antigen-specific Th1-type CD4(+) T-cell-mediated protective immunity against herpes simplex virus type 2 in vivo. (2/85)

Chemokines are inflammatory molecules that act primarily as chemoattractants and as activators of leukocytes. Their role in antigen-specific immune responses is of importance, but their role in disease protection is unknown. Recently it has been suggested that chemokines modulate immunity along more classical Th1 and Th2 phenotypes. However, no data currently exist in an infectious challenge model system. We analyzed the modulatory effects of selected chemokines (interleukin-8 [IL-8], gamma interferon-inducible protein 10 [IP-10], RANTES, monocyte chemotactic protein 1 [MCP-1], and macrophage inflammatory protein 1 alpha [MIP-1 alpha]) on immune phenotype and protection against lethal challenge with herpes simplex virus type 2 (HSV-2). We observed that coinjection with IL-8 and RANTES plasmid DNAs dramatically enhanced antigen-specific Th1 type cellular immune responses and protection from lethal HSV-2 challenge. This enhanced protection appears to be mediated by CD4(+) T cells, as determined by in vitro and in vivo T-cell subset deletion. Thus, IL-8 and RANTES cDNAs used as DNA vaccine adjuvants drive antigen-specific Th1 type CD4(+) T-cell responses, which result in reduced HSV-2-derived morbidity, as well as reduced mortality. However, coinjection with DNAs expressing MCP-1, IP-10, and MIP-1 alpha increased mortality in the challenged mice. Chemokine DNA coinjection also modulated its own production as well as the production of cytokines. These studies demonstrate that chemokines can dominate and drive immune responses with defined phenotypes, playing an important role in the generation of protective antigen-specific immunity.  (+info)

Protective T-cell-based immunity induced in neonatal mice by a single replicative cycle of herpes simplex virus. (3/85)

Newborns are very susceptible to infections because their immune systems are not fully developed and react to antigen exposure preferentially with unresponsiveness. UV-inactivated herpes simplex virus type 1 (HSV-1) represents such an antigen and does not induce an immune response in neonates. In contrast, protective T cells were primed in newborn mice by a single replicative cycle of DISC HSV-1 given once within 24 h of birth. Each of the HSV-1-primed CD4(+) or CD8(+) T cells induced in wild-type or interferon-deficient mice conferred resistance to naive animals exposed to a lethal virus challenge. Inactivated HSV-1, injected at variable doses up to 10(4) times that of DISC HSV-1, was ineffective in inducing any detectable immune responses in neonates. Thus, the capacity of HSV-1 to replicate once, but not the number of virus particles per se, was decisive in inducing protective T-cell-associated immunity in newborn mice.  (+info)

Vaccine-induced serum immunoglobin contributes to protection from herpes simplex virus type 2 genital infection in the presence of immune T cells. (4/85)

Herpes simplex type virus 2 (HSV-2) is a sexually transmitted pathogen that causes genital lesions and spreads to the nervous system to establish acute and latent infections. Systemic but not mucosal cellular and humoral immune responses are elicited by immunization of mice with a replication-defective mutant of HSV-2, yet the mice are protected against disease caused by subsequent challenge of the genital mucosa with virulent HSV-2. In this study, we investigated the role of immune serum antibody generated by immunization with a replication-defective HSV-2 vaccine prototype strain in protection of the genital mucosa and the nervous system from HSV-2 infection. Passive transfer of replication-defective virus-immune serum at physiologic concentrations to SCID or B-cell-deficient mice had no effect on replication of challenge virus in the genital mucosa but did significantly reduce the incidence and severity of genital and neurologic disease. In contrast, B-cell-deficient mice immunized with replication-defective HSV-2 were able to control replication of challenge virus in the genital mucosa, but not until 3 days postchallenge, and were not completely protected against genital and neurologic disease. Passive transfer of physiologic amounts of immune serum to immunized, B-cell-deficient mice completely restored their capacity to limit replication of challenge virus in the genital mucosa and prevented signs of genital and systemic disease. In addition, the numbers of viral genomes in the lumbosacral dorsal root ganglia of immunized, B-cell-deficient mice were dramatically reduced by transfer of immune serum prior to challenge. These results suggest that there is an apparent synergism between immune serum antibody and immune T cells in achieving protection and that serum antibody induced by vaccination with replication-defective virus aids in reducing establishment of latent infection after genital infection with HSV-2.  (+info)

Vaccination to prevent varicella and shingles. (5/85)

Vaccination of healthy children against varicella using the live attenuated Oka vaccine has been available in Japan and south Korea for several years. In 1996, a programme of universal vaccination of children to prevent varicella was introduced in the USA and other countries, including Canada, Germany, and Sweden, have licensed the vaccine for use in healthy children. This article reviews the origin of the Oka vaccine and the evidence for vaccine safety and efficacy in children and adults. Universal vaccination of children and targeted vaccination of groups at risk of severe varicella are discussed. The possible use of the Oka vaccine to prevent zoster is reviewed, and initiatives to develop new varicella zoster virus vaccines are outlined.  (+info)

Detection of bovine herpesvirus-1 in peripheral blood mononuclear cells eight months postinfection. (6/85)

Peripheral blood mononuclear cells (PBMCs) from 5 calves (3 controls and 2 vaccinates) used in a bovine herpesvirus 1 (BHV-1) vaccine study with a BHV-1 Cooper strain challenge were collected 6 months after challenge. The PBMCs from the control animals were positive by immunofluorescence for the BHV-1 glycoprotein D (gD) while the vaccinates were negative. The PBMC samples from 4 of the 5 animals were examined for BHV-1 DNA by polymerase chain reaction (PCR) and for gD immunofluorescence at 8 months after challenge. The BHV-1 DNA and viral antigen were detected in PBMC samples at 8 months postinfection, but no virus was isolated.  (+info)

Priming by DNA immunization augments T-cell responses induced by modified live bovine herpesvirus vaccine. (7/85)

DNA vaccines have several advantages over conventional vaccines. One of the most important characteristics is the presentation of antigen via both MHC class I and class II receptors. Although this generally results in strong T-cell responses, antibody production and protection achieved by DNA immunization are unfortunately not always adequate. In contrast, modified live virus (MLV) vaccines usually induce adequate antibody and moderate cellular responses, whereas killed vaccines tend to elicit weak immune responses in general. A DNA prime-MLV boost regimen should result in enhanced cellular immunity and possibly improved antibody production. To test this hypothesis, plasmids encoding bovine herpesvirus-1 (BHV-1) glycoproteins B and D were delivered by gene gun to the genital mucosa of cattle prior to immunization with modified live BHV-1 vaccine. The immune responses induced were compared to those of an MLV-vaccinated group and a negative control group. Although significantly enhanced T-cell responses were induced by priming with the DNA vaccine, there was no increase in antibody titres. Similar levels of protection were induced by the MLV vaccine alone and the DNA prime and MLV boost regimen, which suggests that there is no correlation between the induction of T-cell responses and protection from BHV-1 challenge.  (+info)

Changes in age related seroprevalence of antibody to varicella zoster virus: impact on vaccine strategy. (8/85)

AIM: To study changes in the seroprevalence of varicella zoster virus (VZV) antibody over the past 25 years with a view to determining the target age group for any future vaccination strategy. METHODS: Stored sera collected from different age groups over a period of 25 years were tested by a commercial VZV IgG enzyme immunoassay at a four year time interval. Data were analysed by logistic regression to investigate the evidence for changes in incidence and hence seroprevalence over that period. RESULTS: There was a significant rise in VZV antibody prevalence in the 1-4 year age group during the study period. CONCLUSIONS: A universal childhood VZV vaccination strategy will need to take account of the increase in incidence of VZV infection in children under the age of 4 years; hence, the suggested target age would be between 12 and 18 months---soon after the disappearance of maternal antibody.  (+info)

Herpesvirus vaccines are immunizations designed to protect against infections caused by herpesviruses. These viruses include herpes simplex virus type 1 (HSV-1), which primarily causes oral herpes, and herpes simplex virus type 2 (HSV-2), which primarily causes genital herpes. Additionally, other herpesviruses such as varicella-zoster virus (VZV), which causes chickenpox and shingles, and cytomegalovirus (CMV), which can cause serious complications in newborns and immunocompromised individuals, are also targeted by herpesvirus vaccines.

Herpesvirus vaccines work by exposing the immune system to a weakened or inactivated form of the virus, or to specific viral proteins, which triggers an immune response. This response includes the production of antibodies and activation of T-cells that recognize and attack the virus if it enters the body in the future.

Currently, there are vaccines available for HSV-1 and HSV-2, but they are not widely used. The only FDA-approved herpesvirus vaccine is for VZV, which is marketed as Varivax and prevents chickenpox and reduces the risk of shingles. There are also several experimental vaccines in development for other herpesviruses, including HSV-1, HSV-2, and CMV.

Medical Definition of "Herpesvirus 8, Human" (HHV-8):

Human Herpesvirus 8 (HHV-8), also known as Kaposi's Sarcoma-associated Herpesvirus (KSHV), is a DNA virus from the family of Herpesviridae. It is the causative agent of several malignancies, including Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD). HHV-8 is primarily transmitted through saliva, sexual contact, or organ transplantation. In immunocompromised individuals, such as those with HIV/AIDS, the risk of HHV-8-associated malignancies significantly increases. The virus establishes latency in infected cells and can periodically reactivate, causing inflammation and potentially leading to the development of cancer.

Human Herpesvirus 6 (HHV-6) is a species of the Roseolovirus genus in the Herpesviridae family. It is a double-stranded DNA virus and is one of the human herpesviruses, which are a group of viruses that includes eight different types that can infect humans.

There are two variants of HHV-6, known as HHV-6A and HHV-6B. Both variants are closely related but have distinct biological properties and clinical manifestations. HHV-6B is the cause of exanthem subitum (also known as roseola infantum or sixth disease), a common childhood illness characterized by fever and rash, while HHV-6A has been associated with various diseases in immunocompromised individuals, such as encephalitis, pneumonitis, and bone marrow suppression.

HHV-6 is highly prevalent in the human population, with most people getting infected during early childhood. After the initial infection, the virus remains latent in the body for the rest of a person's life, and it can reactivate under certain conditions, such as immune suppression or stress. Reactivation of HHV-6 has been associated with various diseases, including encephalitis, seizures, and fatigue.

It is important to note that while HHV-6 infection is common, most people do not develop any symptoms or long-term complications. However, in some cases, the virus can cause significant illness, especially in immunocompromised individuals.

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. It typically contains an agent that resembles the disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it encounters in the future.

Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic (to fight disease that is already present). The administration of vaccines is called vaccination. Vaccinations are generally administered through needle injections, but can also be administered by mouth or sprayed into the nose.

The term "vaccine" comes from Edward Jenner's 1796 use of cowpox to create immunity to smallpox. The first successful vaccine was developed in 1796 by Edward Jenner, who showed that milkmaids who had contracted cowpox did not get smallpox. He reasoned that exposure to cowpox protected against smallpox and tested his theory by injecting a boy with pus from a cowpox sore and then exposing him to smallpox, which the boy did not contract. The word "vaccine" is derived from Variolae vaccinae (smallpox of the cow), the term devised by Jenner to denote cowpox. He used it in 1798 during a conversation with a fellow physician and later in the title of his 1801 Inquiry.

Herpesvirus 2, Saimiriine (SaHV-2) is a species of herpesvirus that primarily infects the primate species Saimiri sciureus, also known as the squirrel monkey. It is a member of the genus Rhadinovirus in the subfamily Gammaherpesvirinae. SaHV-2 has been associated with lymphoproliferative diseases and lymphomas in its natural host. The virus has a complex structure, consisting of an outer envelope, a protein layer called the capsid, and a DNA genome. It employs a sophisticated replication strategy to establish latency and evade the host's immune response.

It is important to note that SaHV-2 does not infect humans and is primarily studied in the context of comparative primatology and viral pathogenesis research.

Herpesvirus 1, Equid (EHV-1) is a DNA virus belonging to the family Herpesviridae and subfamily Alphaherpesvirinae. It is a species-specific virus that primarily infects horses, donkeys, and mules. The virus is also known as equine abortion virus, equine rhinitis virus type A, and equine herpesvirus 1.

EHV-1 can cause a range of clinical signs in infected animals, including respiratory disease, abortion in pregnant mares, and neurological disorders. The virus is primarily spread through direct contact with infected animals or their respiratory secretions, and it can also be spread through contaminated objects such as tack and feed buckets.

Once an animal is infected with EHV-1, the virus becomes latent in the nervous system and may reactivate later, causing recurrent disease. There is no cure for EHV-1 infection, but vaccines are available to help reduce the severity of clinical signs and prevent the spread of the virus.

Herpesviridae is a family of large, double-stranded DNA viruses that includes several important pathogens affecting humans and animals. The herpesviruses are characterized by their ability to establish latency in infected host cells, allowing them to persist for the lifetime of the host and leading to recurrent episodes of disease.

The family Herpesviridae is divided into three subfamilies: Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae. Each subfamily includes several genera and species that infect various hosts, including humans, primates, rodents, birds, and reptiles.

Human herpesviruses include:

* Alphaherpesvirinae: Herpes simplex virus type 1 (HSV-1), Herpes simplex virus type 2 (HSV-2), and Varicella-zoster virus (VZV)
* Betaherpesvirinae: Human cytomegalovirus (HCMV), Human herpesvirus 6A (HHV-6A), Human herpesvirus 6B (HHV-6B), and Human herpesvirus 7 (HHV-7)
* Gammaherpesvirinae: Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV, also known as HHV-8)

These viruses are responsible for a wide range of clinical manifestations, from mild skin lesions to life-threatening diseases. Primary infections usually occur during childhood or adolescence and can be followed by recurrent episodes due to virus reactivation from latency.

Bovine Herpesvirus 1 (BoHV-1) is a species-specific virus that belongs to the family Herpesviridae, subfamily Alphaherpesvirinae, and genus Varicellovirus. This virus is the causative agent of Infectious Bovine Rhinotracheitis (IBR), which is a significant respiratory disease in cattle. The infection can also lead to reproductive issues, including abortions, stillbirths, and inflammation of the genital tract (infectious pustular vulvovaginitis) in cows and infertility in bulls.

The virus is primarily transmitted through direct contact with infected animals, their respiratory secretions, or contaminated objects. Once an animal is infected, BoHV-1 establishes a lifelong latency in the nervous system, from where it can periodically reactivate and shed the virus, even without showing any clinical signs. This makes eradication of the virus challenging in cattle populations.

Vaccines are available to control IBR, but they may not prevent infection or shedding entirely. Therefore, ongoing management practices, such as biosecurity measures and surveillance programs, are essential to minimize the impact of this disease on cattle health and productivity.

Inactivated vaccines, also known as killed or non-live vaccines, are created by using a version of the virus or bacteria that has been grown in a laboratory and then killed or inactivated with chemicals, heat, or radiation. This process renders the organism unable to cause disease, but still capable of stimulating an immune response when introduced into the body.

Inactivated vaccines are generally considered safer than live attenuated vaccines since they cannot revert back to a virulent form and cause illness. However, they may require multiple doses or booster shots to maintain immunity because the immune response generated by inactivated vaccines is not as robust as that produced by live vaccines. Examples of inactivated vaccines include those for hepatitis A, rabies, and influenza (inactivated flu vaccine).

Herpesviridae infections refer to diseases caused by the Herpesviridae family of double-stranded DNA viruses, which include herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2), varicella-zoster virus (VZV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6), human herpesvirus 7 (HHV-7), and human herpesvirus 8 (HHV-8). These viruses can cause a variety of clinical manifestations, ranging from mild skin lesions to severe systemic diseases.

After the initial infection, these viruses typically become latent in various tissues and may reactivate later in life, causing recurrent symptoms. The clinical presentation of Herpesviridae infections depends on the specific virus and the immune status of the host. Common manifestations include oral or genital ulcers (HSV-1 and HSV-2), chickenpox and shingles (VZV), mononucleosis (CMV), roseola (HHV-6), and Kaposi's sarcoma (HHV-8).

Preventive measures include avoiding close contact with infected individuals during the active phase of the infection, practicing safe sex, and avoiding sharing personal items that may come into contact with infectious lesions. Antiviral medications are available to treat Herpesviridae infections and reduce the severity and duration of symptoms.

A viral vaccine is a biological preparation that introduces your body to a specific virus in a way that helps your immune system build up protection against the virus without causing the illness. Viral vaccines can be made from weakened or inactivated forms of the virus, or parts of the virus such as proteins or sugars. Once introduced to the body, the immune system recognizes the virus as foreign and produces an immune response, including the production of antibodies. These antibodies remain in the body and provide immunity against future infection with that specific virus.

Viral vaccines are important tools for preventing infectious diseases caused by viruses, such as influenza, measles, mumps, rubella, polio, hepatitis A and B, rabies, rotavirus, chickenpox, shingles, and some types of cancer. Vaccination programs have led to the control or elimination of many infectious diseases that were once common.

It's important to note that viral vaccines are not effective against bacterial infections, and separate vaccines must be developed for each type of virus. Additionally, because viruses can mutate over time, it is necessary to update some viral vaccines periodically to ensure continued protection.

Human Herpesvirus 7 (HHV-7) is a species of the Herpesviridae family and Betaherpesvirinae subfamily. It is a double-stranded DNA virus that primarily infects human hosts. HHV-7 is closely related to Human Herpesvirus 6 (HHV-6) and both viruses share many biological and biochemical properties.

HHV-7 is typically acquired in early childhood, with most people becoming infected before the age of five. Primary infection with HHV-7 can cause a mild illness known as exanthema subitum or roseola infantum, which is characterized by fever and a rash. However, many HHV-7 infections are asymptomatic.

After initial infection, HHV-7 becomes latent in the host's immune cells, particularly CD4+ T-lymphocytes. The virus can reactivate later in life, causing various clinical manifestations such as chronic fatigue syndrome, seizures, and exacerbation of atopic dermatitis. HHV-7 has also been implicated in the development of certain malignancies, including lymphoproliferative disorders and some types of brain tumors.

Like other herpesviruses, HHV-7 establishes a lifelong infection in its human host, with periodic reactivation throughout the individual's lifetime.

I could not find a specific medical definition for "Vaccines, DNA." However, I can provide you with some information about DNA vaccines.

DNA vaccines are a type of vaccine that uses genetically engineered DNA to stimulate an immune response in the body. They work by introducing a small piece of DNA into the body that contains the genetic code for a specific antigen (a substance that triggers an immune response). The cells of the body then use this DNA to produce the antigen, which prompts the immune system to recognize and attack it.

DNA vaccines have several advantages over traditional vaccines. They are relatively easy to produce, can be stored at room temperature, and can be designed to protect against a wide range of diseases. Additionally, because they use DNA to stimulate an immune response, DNA vaccines do not require the growth and culture of viruses or bacteria, which can make them safer than traditional vaccines.

DNA vaccines are still in the experimental stages, and more research is needed to determine their safety and effectiveness. However, they have shown promise in animal studies and are being investigated as a potential tool for preventing a variety of infectious diseases, including influenza, HIV, and cancer.

Synthetic vaccines are artificially produced, designed to stimulate an immune response and provide protection against specific diseases. Unlike traditional vaccines that are derived from weakened or killed pathogens, synthetic vaccines are created using synthetic components, such as synthesized viral proteins, DNA, or RNA. These components mimic the disease-causing agent and trigger an immune response without causing the actual disease. The use of synthetic vaccines offers advantages in terms of safety, consistency, and scalability in production, making them valuable tools for preventing infectious diseases.

Combined vaccines are defined in medical terms as vaccines that contain two or more antigens from different diseases, which are given to provide protection against multiple diseases at the same time. This approach reduces the number of injections required and simplifies the immunization schedule, especially during early childhood. Examples of combined vaccines include:

1. DTaP-Hib-IPV (e.g., Pentacel): A vaccine that combines diphtheria, tetanus, pertussis (whooping cough), Haemophilus influenzae type b (Hib) disease, and poliovirus components in one injection to protect against these five diseases.
2. MMRV (e.g., ProQuad): A vaccine that combines measles, mumps, rubella, and varicella (chickenpox) antigens in a single injection to provide immunity against all four diseases.
3. HepA-HepB (e.g., Twinrix): A vaccine that combines hepatitis A and hepatitis B antigens in one injection, providing protection against both types of hepatitis.
4. MenACWY-TT (e.g., MenQuadfi): A vaccine that combines four serogroups of meningococcal bacteria (A, C, W, Y) with tetanus toxoid as a carrier protein in one injection for the prevention of invasive meningococcal disease caused by these serogroups.
5. PCV13-PPSV23 (e.g., Vaxneuvance): A vaccine that combines 13 pneumococcal serotypes with PPSV23, providing protection against a broader range of pneumococcal diseases in adults aged 18 years and older.

Combined vaccines have been thoroughly tested for safety and efficacy to ensure they provide a strong immune response and an acceptable safety profile. They are essential tools in preventing various infectious diseases and improving overall public health.

Bacterial vaccines are types of vaccines that are created using bacteria or parts of bacteria as the immunogen, which is the substance that triggers an immune response in the body. The purpose of a bacterial vaccine is to stimulate the immune system to develop protection against specific bacterial infections.

There are several types of bacterial vaccines, including:

1. Inactivated or killed whole-cell vaccines: These vaccines contain entire bacteria that have been killed or inactivated through various methods, such as heat or chemicals. The bacteria can no longer cause disease, but they still retain the ability to stimulate an immune response.
2. Subunit, protein, or polysaccharide vaccines: These vaccines use specific components of the bacterium, such as proteins or polysaccharides, that are known to trigger an immune response. By using only these components, the vaccine can avoid using the entire bacterium, which may reduce the risk of adverse reactions.
3. Live attenuated vaccines: These vaccines contain live bacteria that have been weakened or attenuated so that they cannot cause disease but still retain the ability to stimulate an immune response. This type of vaccine can provide long-lasting immunity, but it may not be suitable for people with weakened immune systems.

Bacterial vaccines are essential tools in preventing and controlling bacterial infections, reducing the burden of diseases such as tuberculosis, pneumococcal disease, meningococcal disease, and Haemophilus influenzae type b (Hib) disease. They work by exposing the immune system to a harmless form of the bacteria or its components, which triggers the production of antibodies and memory cells that can recognize and fight off future infections with that same bacterium.

It's important to note that while vaccines are generally safe and effective, they may cause mild side effects such as pain, redness, or swelling at the injection site, fever, or fatigue. Serious side effects are rare but can occur, so it's essential to consult with a healthcare provider before receiving any vaccine.

An AIDS vaccine is a type of preventive vaccine that aims to stimulate the immune system to produce an effective response against the human immunodeficiency virus (HIV), which causes acquired immunodeficiency syndrome (AIDS). The goal of an AIDS vaccine is to induce the production of immune cells and proteins that can recognize and eliminate HIV-infected cells, thereby preventing the establishment of a persistent infection.

Despite decades of research, there is still no licensed AIDS vaccine available. This is due in part to the unique challenges posed by HIV, which has a high mutation rate and can rapidly evolve to evade the immune system's defenses. However, several promising vaccine candidates are currently being tested in clinical trials around the world, and researchers continue to explore new approaches and strategies for developing an effective AIDS vaccine.

Cytomegalovirus (CMV) vaccines are medical products being developed to prevent or ameliorate infection and disease caused by the human cytomegalovirus. CMV is a type of herpesvirus that can cause serious health problems in people with weakened immune systems, such as those undergoing organ transplantation, people living with HIV/AIDS, and newborns infected with the virus before birth (congenital CMV infection).

There are currently no approved vaccines for CMV. However, several vaccine candidates are being investigated in clinical trials to evaluate their safety, immunogenicity, and efficacy. These vaccine candidates use various approaches, such as:

1. Live-attenuated viruses: These vaccines contain weakened forms of the virus that can stimulate an immune response without causing disease. An example is the Towne vaccine, which has been studied in clinical trials for several decades.
2. Recombinant proteins: These vaccines use specific viral proteins to induce an immune response. For instance, a glycoprotein B (gB) subunit vaccine has shown promising results in phase II clinical trials.
3. Virus-like particles (VLPs): VLPs mimic the structure of the virus but do not contain any viral genetic material. They can be used to induce an immune response without causing infection.
4. DNA vaccines: These vaccines use plasmids containing CMV genes to stimulate an immune response. A DNA vaccine encoding the CMV phosphoprotein 65 (pp65) has been tested in clinical trials.
5. mRNA vaccines: Similar to DNA vaccines, mRNA vaccines use genetic material to induce an immune response. Moderna Therapeutics is developing an mRNA vaccine candidate for CMV.

The development of a safe and effective CMV vaccine remains a significant public health priority, as CMV infection can lead to severe complications in vulnerable populations.

Cytomegalovirus (CMV) is a type of herpesvirus that can cause infection in humans. It is characterized by the enlargement of infected cells (cytomegaly) and is typically transmitted through close contact with an infected person, such as through saliva, urine, breast milk, or sexual contact.

CMV infection can also be acquired through organ transplantation, blood transfusions, or during pregnancy from mother to fetus. While many people infected with CMV experience no symptoms, it can cause serious complications in individuals with weakened immune systems, such as those undergoing cancer treatment or those who have HIV/AIDS.

In newborns, congenital CMV infection can lead to hearing loss, vision problems, and developmental delays. Pregnant women who become infected with CMV for the first time during pregnancy are at higher risk of transmitting the virus to their unborn child. There is no cure for CMV, but antiviral medications can help manage symptoms and reduce the risk of complications in severe cases.

Cytomegalovirus (CMV) infections are caused by the human herpesvirus 5 (HHV-5), a type of herpesvirus. The infection can affect people of all ages, but it is more common in individuals with weakened immune systems, such as those with HIV/AIDS or who have undergone organ transplantation.

CMV can be spread through close contact with an infected person's saliva, urine, blood, tears, semen, or breast milk. It can also be spread through sexual contact or by sharing contaminated objects, such as toys, eating utensils, or drinking glasses. Once a person is infected with CMV, the virus remains in their body for life and can reactivate later, causing symptoms to recur.

Most people who are infected with CMV do not experience any symptoms, but some may develop a mononucleosis-like illness, characterized by fever, fatigue, swollen glands, and sore throat. In people with weakened immune systems, CMV infections can cause more severe symptoms, including pneumonia, gastrointestinal disease, retinitis, and encephalitis.

Congenital CMV infection occurs when a pregnant woman passes the virus to her fetus through the placenta. This can lead to serious complications, such as hearing loss, vision loss, developmental delays, and mental disability.

Diagnosis of CMV infections is typically made through blood tests or by detecting the virus in bodily fluids, such as urine or saliva. Treatment depends on the severity of the infection and the patient's overall health. Antiviral medications may be prescribed to help manage symptoms and prevent complications.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Nervous system diseases, also known as neurological disorders, refer to a group of conditions that affect the nervous system, which includes the brain, spinal cord, nerves, and muscles. These diseases can affect various functions of the body, such as movement, sensation, cognition, and behavior. They can be caused by genetics, infections, injuries, degeneration, or tumors. Examples of nervous system diseases include Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, migraine, stroke, and neuroinfections like meningitis and encephalitis. The symptoms and severity of these disorders can vary widely, ranging from mild to severe and debilitating.

An immunocompromised host refers to an individual who has a weakened or impaired immune system, making them more susceptible to infections and decreased ability to fight off pathogens. This condition can be congenital (present at birth) or acquired (developed during one's lifetime).

Acquired immunocompromised states may result from various factors such as medical treatments (e.g., chemotherapy, radiation therapy, immunosuppressive drugs), infections (e.g., HIV/AIDS), chronic diseases (e.g., diabetes, malnutrition, liver disease), or aging.

Immunocompromised hosts are at a higher risk for developing severe and life-threatening infections due to their reduced immune response. Therefore, they require special consideration when it comes to prevention, diagnosis, and treatment of infectious diseases.
