Pfizer is making a vaccine specifically targeting the Delta variant, but the company's CEO Albert Bourla said Monday he doesn’t think it will be needed because the current vaccine is so effective.
“We are making right now a specialized vaccine for Delta,” Bourla told NBC Nightly News. “I'm almost certain that we will not need it.”
That’s because Pfizer’s current Covid-19 vaccine is already working well against the variant, he noted.
“The current vaccine is very, very, very effective against Delta, but we cannot take that chance,” Bourla said.
