Although previous studies have shown that vaccination-induced immunity has been maintained for more than three decades, 11 immunity still wanes with time since vaccination. (nature.com)
The U.S. is farther down the path to herd immunity on COVID-19 than Canada due to two factors: higher infection rates at the outset and, now, much higher vaccination rates, including this health-care worker in Michigan on Jan. 5. (cbc.ca)
The recommendations for vaccinating HCP are presented by disease in two categories: 1) those diseases for which vaccination or documentation of immunity is recommended because of risks to HCP in their work settings for acquiring disease or transmitting to patients and 2) those for which vaccination might be indicated in certain circumstances. (cdc.gov)
The new guidelines feature changes in the evidence required for measles immunity, the use of immune globulin, vaccination for healthcare personnel, and the management of patients with HIV infections and other susceptibilities. (medscape.com)
The oft-parroted sound bite - "we need herd immunity"- implies that if ninety five percent of the population can become "immune" to a disease via vaccination , target immunity levels will be met and diseases will either be eradicated or controlled. (greenmedinfo.com)
Herd immunity" is the trump card for the defense of vaccination on TV, Internet, medical journals and newspapers as to why we should be vaccinated over and over throughout our lives, with an ever-increasing number of vaccines. (greenmedinfo.com)
Since the beginning of vaccination, there is little proof that vaccines are responsible for eradicating disease even when herd immunity vaccination levels have been reached. (greenmedinfo.com)
Prior to the universal varicella vaccination program, 95% of adults experienced natural chickenpox (usually as school aged children)-these cases were usually benign and resulted in long term immunity. (greenmedinfo.com)
This high percentage of individuals having long term immunity has been compromised by mass vaccination of children which provides at best 70 to 90% immunity that is temporary and of unknown duration-shifting chickenpox to a more vulnerable adult population where chickenpox carries 20 times more risk of death and 15 times more risk of hospitalization compared to children. (greenmedinfo.com)
October 31, 2022 -- A genetic timestamping mouse model has shown the rate at which antibody-producing cells accumulate and disappear after vaccination, which could ultimately allow researchers to be able to increase the longevity of immunity from vaccines. (scienceboard.net)
Timestamping showed when the cells were made, thereby revealing which were the persistent LLPCs that are central to long-lasting immunity after vaccination. (scienceboard.net)
IgG levels can be explained by current infection, immunity due to past infection or vaccination, or maternal antibodies present in infants younger than 15 months. (medscape.com)
Vaccination does not always lead to immunity and protection against infection. (cornell.edu)
Most calf vaccination programs start at or after 4 months of age to take into account the calf's own ability to respond as well as waiting for a decline in colostral or passive immunity from the dam. (cornell.edu)
Maternal antibody from colostrum (passive immunity) protects calves against disease until they develop their own antibodies in response to vaccination or infection (active immunity). (cornell.edu)
Colostral immunity also can potentially interfere with a calf's immune response to vaccination. (cornell.edu)
Although vaccine-induced immunity is not complete, vaccination continues to be one of the most important prevention measures. (cdc.gov)
This outbreak had a peak of about 460 cases per day in August 2022, and gradually declined, likely because of a combination of temporary changes in sexual behavior, vaccination, and infection-induced immunity[1,2]. (cdc.gov)
Adhering to the recommended vaccination schedule maximizes the chances of immunity against parvo. (stopsmartmetersbc.ca)
However, maternal immunity is temporary and starts declining after several weeks, making vaccination crucial for long-term protection. (stopsmartmetersbc.ca)

Using different vaccine combinations or delivery strategies could create a longer-lasting reservoir of LLPCs and thereby provide more durable immunity. (scienceboard.net)
However, the protection may have a limited duration and it may be dependent on the antigenic relatedness of vaccine and field virus. (usda.gov)
To answer that question, we need to talk about the DOI , which is the moment in time at which vaccine-induced immunity begins to decline and provides less protection for a fully vaccinated animal. (pigprogress.net)
wide range of assumptions about vaccine efficacy and duration of vaccine-conferred immunity. (cdc.gov)
Evidence has demonstrated sustained vaccine efficacy after a single 0.5ml dose for a period of up to 12 weeks (3 months), yet antibody concentrations declined by 34% through 90 days .2 Limited data is available on the duration of efficacy or rapidly waning immunity past 12 weeks, and a second dose has been shown to maintain high efficacy. (who.int)

Here, we recruited 294 volunteers and detected the level of residual humoral immunity, including the vaccinia-specific IgG level and neutralizing antibody titer, and the cross-antibodies of MPXV A29L, B6R, A35R, and M1R. (nature.com)
Antibody duration and the significance of particular antibodies, such as neutralizing antibodies, also remains elusive. (medscape.com)
A standard proxy for immunity is the presence of Y-shaped immune proteins known as antibodies , especially so-called neutralizing antibodies that can glom on and clear invading viral particles even before the virus can enter cells. (factcheck.org)
So far, data suggest that most people generate antibodies in response to SARS-CoV-2 infection, and that those molecules persist for at least a few months, although some studies have reported more limited durations. (factcheck.org)
The cells, which can persist for decades, produce high-affinity antibodies that provide durable protective immunity against pathogens. (scienceboard.net)

The hype about herd immunity unfortunately creates a wall of hostility between those who vaccinate and those who delay some vaccines, avoid certain vaccines, or quit vaccinating altogether. (greenmedinfo.com)
The population of the world is expanding over the past 200 years where vaccines have been used, and this makes obtaining herd immunity even more expensive and impossible today than ever. (greenmedinfo.com)
As these resident memory T cells are long lived, vaccines that are able to induce them should provide long-lasting immunity. (frontiersin.org)
