As two new stains of the virus spread globally, Pfizer and BioNTech are also developing booster shots that can protect against various mutations.

“Every time a new variant comes up we should be able to test whether or not [our vaccine] is effective,” Bourla said. “Once we discover something that it is not as effective, we will very, very quickly be able to produce a booster dose that will be a small variation to the current vaccine.”
