Each year more than 500 million doses of seasonal influenza vaccine are administered around the world, with most doses being egg-grown inactivated subunit or split-virion vaccines. These vaccines tend to have moderate effectiveness against medically attended influenza for influenza A(H1N1) and ...
Strategies employed to improve vaccine efficacy involve using structure-based design and nanoparticle display to optimize the antigenicity and immunogenicity of target antigens; increasing the antigen dose; using novel adjuvants; stimulating cellular immunity; and targeting other viral proteins, including ...

CDC, other experts are tracking increases in respiratory syncytial virus cases in infants. Fighting flu vaccine misconceptions Rachael Zimlich, RN, BSN February 2nd 2022 A new poll suggests that misconceptions about the flu vaccine are at a three-year high, despite the fact that more patients seem...
culture for growth of vaccine stock also does not appreciably shorten the time from strain selection to vaccine administration (Hegde, 2015). In total, these factors result in vaccines that have variable efficacy from year to year. The CDC estimates an average vaccine effectiveness of 40%–60%....
studies monitoring the clinical benefit and risk profile of seasonal influenza vaccines should be strengthened, whereas providing immunogenicity data from small clinical trials should no longer be conducted, since these data might not correlate to the expected efficacy and safety of the vaccine [31]. ...
circulating H3N2 strain that had undergone antigenic drift over time. Even so, it is important to remind patients that receiving the influenza vaccine each year, preferably before the end of October each year per CDC recommendations, is the best way to reduce the risk of developing influe...
Influenza vaccination rates remain low despite much convincing evidence about the benefits of the vaccine. From 2018 to 2019, the vaccination rate among adults was estimated at 45.3%. Even with relatively low coverage, the CDC estimated that the vaccine prevented approximately 4.4 million influenza ca...
In February of any given year, the WHO and the U.S. CDC study which flu viruses are emerging around the world and choose a combination of candidate strains for the production of the vaccine to be used in November. In general, these seasonal flu vaccines are formulated to contain antigens...
