Starting this fall, however, all the flu shots distributed in the United States will probably contain only three strains, and the change is because of Covid-19.
It’s not quick or easy to change how flu vaccines are manufactured, and those changes require regulatory review and approval.
The committee is meeting Tuesday to discuss next steps and vote on flu vaccine recommendations for the fall.
“Anytime these flu vaccines are being produced, they are – depending on which vaccines you are talking about – using live or attenuated virus, and you do have to grow it,” she said.
But as the authors note, any such change would require testing and regulatory approval, and for that reason, it’s not likely we’ll see the return of four-strain flu shots any time soon.
