CDC Study Points to Potential Benefits of Newer Flu Vaccines

A recent CDC study suggests that non-egg-based flu vaccines may enhance the antibody response to circulating flu viruses compared to traditional egg-based vaccines, which are widely used globally. The research assessed people's immune reactions to different flu vaccines to identify those inducing the most effective antibody response to circulating influenza viruses.


For over 70 years, flu vaccines have primarily been egg-based, but this method's "egg-adapted changes" can decrease effectiveness by prompting the immune system to target different epitopes than those on circulating flu viruses. Read more from the CDC here.
