The CDC analyzes the vaccine subtypes each year and makes any necessary changes for the coming season on the basis of worldwide trends. (medscape.com)
This study aimed to assess the molecular and seasonal pattern of influenza virus subtypes in western Saudi Arabia to inform policy decisions on influenza vaccine. (atlantis-press.com)

The US Centers for Disease Control and Prevention previously issued interim clinical considerations stating that 'COVID-19 vaccines and other vaccines, including influenza vaccines , can be administered without regard to timing. (flutalk.net)
It is more important now than ever to get a flu vaccine because flu symptoms are very similar to those of COVID-19 and preventing the flu will save lives and preserve health care resources," said Dr. Larry Madoff, medical director of the Bureau of Infectious Disease and Laboratory Sciences at the Massachusetts Department of Public Health. (etinside.com)
While the flu vaccine is an important preventative measure every year, it is arguably more important than ever in the midst of the COVID-19 pandemic. (healthtrustjobs.com)
While we wait for COVID vaccines to be broadly available, the flu remains the number one cause of vaccine-preventable death in the United States," explains Dr. Jonathan Perlin, president of clinical operations and chief medical officer at HCA Healthcare. (healthtrustjobs.com)

In the Northern Hemisphere, all persons aged 6 months or older should receive influenza vaccine annually by the end of October, if possible. (medscape.com)

Those with a history of egg allergy who have experienced only hives after exposure to egg should receive influenza vaccine. (medscape.com)

Injectable vaccine, which contains inactivated virus, is available in a variety of dosage forms. (medscape.com)
This shortened and simplified dosage schedule is anticipated to improve hepatitis B vaccine coverage. (immunize.org)

Under investigation in this study were egg-based flu vaccines, which the team found cause the human immune system to partially produce antibodies with an avian receptor preference. (contagionlive.com)
Vaccines that don't use avian cells may be more effective at producing broadly-neutralizing antibodies than egg-based vaccines, and thus, prove to be more effective at preventing illness. (contagionlive.com)
Overview of Immunization Immunity can be achieved Actively by using antigens (eg, vaccines, toxoids) Passively by using antibodies (eg, immune globulins, antitoxins) A toxoid is a bacterial toxin that has been modified. (msdmanuals.com)

This study aimed to explore factors related to the immune response to influenza vaccines. (biomedcentral.com)
The Chi-square test, multivariable logistic regression analysis, and sum-rank test were used to analyze the factors associated with influenza vaccine immune response. (biomedcentral.com)
As we get older, our immune systems have a harder time responding to illnesses and vaccines. (flutalk.net)
FLUAD pairs the regular vaccine with an adjuvant, an immune stimulant, to cause the immune system to have a higher response to the vaccine. (etinside.com)
That's just your body working on the vaccine and your immune response responding to the vaccine," he said. (etinside.com)

Racial and ethnic disparities in flu vaccine uptake persisted for children and adults. (cdc.gov)
The low uptake of influenza vaccine in hospital staff and their dependents is a matter of concern and should be addressed by greater awareness and education. (who.int)

[ 8 ] With an inactivated virus vaccine, the amount of antigen required to induce immunity is much greater than that for a live-attenuated virus vaccine, because unlike the live-attenuated virus, the inactivated virus does not replicate in the recipient. (medscape.com)
Thus, being able to obtain large quantities of virus in the allantoic fluid overcame this problem and an inactivated vaccine with a sufficiently high concentration of antigen could be prepared, after a simple, rapid purification process. (medscape.com)
In addition, manufacturers developed live attenuated, adjuvanted and whole virion inactivated pandemic vaccines, which met regulatory requirements with far lower antigen contents than are used in seasonal inactivated vaccines. (micrornainhibitor.com)

Immunosuppressants also increase risk of infection with concomitant live vaccines. (medscape.com)

In 1944, Stanley described in detail the preparation and properties of influenza virus vaccine produced in embryonated hen eggs, concentrated and purified by differential centrifugation and inactivated by different procedures. (medscape.com)

But the organizations note that the vaccine had been given to millions of pregnant women over the last decade and had not been shown to harm either the women or their infants. (blogspot.com)
Dr. Flor Munoz would like to disclose that the use of influenza antivirals in hospitalized, severely ill patients is off label, and the use of influenza vaccines in pregnant women is off label. (cdc.gov)
Inactivated influenza vaccine (IIV) can be given to all people ≥ 6 months, including pregnant women. (msdmanuals.com)
