The French are among the most reluctant people in the world to get a COVID-19 shot because of distrust of the government and past health scandals.
Dr. Anthony Fauci, the top U.S. infectious-disease expert, recently said vaccines were designed to recognize multiple parts of the spike protein, making it unlikely a single mutation could be enough to block them. But scientists around the world are conducting research with different vaccines to find out.
Dormitzer said if the coronavirus eventually mutates enough that the vaccine needs adjusting — much like flu shots are adjusted most years — that tweaking of the recipe wouldn’t be difficult for his company’s shot and similar ones. The vaccine is made with a piece of the coronavirus’ genetic code, which is simple to switch, although it’s not clear what kind of additional testing regulators would require to make such a change.
Dormitzer said this was only the beginning “of ongoing monitoring of virus changes to see if any of them might impact on vaccine coverage.”
