FDA Commissioner Dr. Robert Califf said in a statement on the subject, “Evidence from existing mRNA Covid-19 vaccines administered to millions of people shows us that the vaccines are safe” said.
Emphasizing that updating existing vaccines to protect against different strains does not require a change in vaccine content, Califf stated that this is a common practice in flu vaccines and added;
“The FDA has extensive experience in reviewing strain changes in vaccines, as does the annual flu shot.”
The European Medicines Agency (EMA) announced that the updated vaccines would be approved by autumn.

Professor William Schaffner of Vanderbilt University pointed out that clinical trials take a long time and “If we had waited for clinical-trial results, the vaccines would only come in the spring. These vaccines are just an update of the vaccines we have used before.” said.
