Currently available flu vaccines are based on the rapidly changing viral hemagglutinin (HA) antigen, and are therefore quickly outdated. Thus new vaccines need to be developed each year. Now, a new study published in the journal Science on October 25, 2019, reports on a set of three novel antibodies that bind to another type of...

Needle-free flu vaccine patch effective in early study
by University of Rochester Medical Center A new needle-free flu vaccine patch revved up the immune system much like a traditional flu shot without any negative side effects, according to a study published in the Journal of Investigative Dermatology. Though the research is in the early stages (the patch hasn’t been tested in humans), it’s...

Disrupting the gut microbiome may affect some immune responses to flu vaccination
Posted Today The normal human gut microbiome is a flourishing community of microorganisms, some of which can affect the human immune system. In a new paper published in Cell, researchers found that oral antibiotics, which can kill gut microorganisms, can alter the human immune response to seasonal influenza vaccination. The work was led by scientists at Stanford University and funded by the National Institute of Allergy and Infectious Diseases (NIAID), part...

Women’s stronger immune response to flu vaccination diminishes with age
Study of flu vaccine responses in humans and mice finds evidence that estrogen boosts vaccine immunity while testosterone lowers it JOHNS HOPKINS UNIVERSITY BLOOMBERG SCHOOL OF PUBLIC HEALTH Women tend to have a greater immune response to a flu vaccination compared to men, but their advantage largely disappears as they age and their estrogen levels decline, suggests...

Every fall, we line up to get our flu shots with the hope that we will be protected from the virus that infects 10 to 20 percent of people worldwide each year. But some years, the vaccine is less effective than others. Every year,...

A universal vaccine to protect people from most strains of flu may be a step closer to reality
A universal vaccine to protect people from most strains of flu may be a step closer to reality. Scientists say they have developed a vaccine which may only need to be given a few times over someone’s life, instead of a new one each year. Current vaccines, offered during flu seasons, can become outdated quickly...

Long-lasting flu vaccine may only take one jab per decade
A new long-lasting flu vaccine could cut back the frequency of the jab to once every 10 years Getting a flu shot is an unpleasant annual routine for many people, but the virus’ tendency to constantly evolve makes it a necessity. Now researchers from Cornell University have developed a new vaccine that acts faster,...
