Pfizer ready to make COVID vaccines for new variants, CEO says

Pfizer's CEO Albert Bourla is expressing confidence about the efficacy of his company's COVID-19 vaccine against the Delta variant, which was first detected in India, as reported by MSN.

"I feel quite comfortable that we cover it," Bourla remarked, adding "we will not need a special vaccine for it. The current vaccine should cover it."

Bourla also believes Pfizer is ready to leap into action with new vaccines to protect against the possible variants within 100 days.

"We have surveillance systems in all the countries — all over the world —when a new variant emerges, immediately, we are testing how the current vaccine behaves compared to this variant," he said. 

Meanwhile, by fall, Pfizer also hopes to reformulate its COVID-19 vaccine so it will not require super cold storage, and it anticipates the vaccine will also be approved for children as young as five. 

Bourla explained that the goal was herd immunity, saying "when you reach herd immunity, you protect the others as well, and kids will play a significant part in doing that."
