The next generation of COVID-19 vaccines should be able to fight off a new strain and be given each year, a panel of experts advising the FDA said Wednesday.
. Instead, public health officials have looked at rates of hospitalizations and deaths to measure whether the vaccine is still offering protection.
CDC officials presented data showing that a third shot has been more effective than a two-shot regimen in preventing serious disease and death, and that the three shots were significantly more protective than being unvaccinated. But only 98 million Americans — about half of those aged 12 or older -- have received a third dose, Scobie said.
COVID outbreaks have happened during all seasons and new variants haven’t always hit every country in a similar fashion. The COVID virus has mutated at five times the speed of the flu virus — producing a new dominant strain in a year, compared to the 3-to-5-years it takes for the flu virus to do so, said Trevor Bedford, PhD, a professor in the vaccine and infectious disease division at the Fred Hutchinson Cancer Research Center in Seattle.
