At a live axios event on May 19, there were several questions about the future of vaccination. CEO of PfizerAlbert Bourla offered his grip when you need aextra dose the vaccine to strengthen immunity. "The data I see to come, they support the notion that there will probably need a booster between eight and 12 months," he said.

As Bourla pointed out, it means that people who received the first rounds of the vaccine might need a booster shot in September or October. The CEO also stated that the Company is working on the "new version" of the Pfizer vaccine that will help to facilitate distribution and administration. Shooting updated "will be a vaccine ready for use, so you do not need to rebuild it, you do not need to dilute it," said Bourla. This vaccine could be stored up At six months of normal refrigeration, which mitigates the number of vaccines that go to waste due to inappropriate storage.

CEO of ModernaStéphane Bantel also weighed on the discussion on the booster vaccine. In an email in Axios, he wrote: "I think like a country we should rather beTwo months too early More than two months too late with epidemics in several places.

But while many experts are content with the need for additional doses are imminent, others are not so sure. Professor and Virologist CornellJohn Moore, PhD, pointed out Axios that there is no evidence that we will need boosters. "Now we have no evidence that protective immunity has dropped to a troubling point, and certainly not for people immunized in December, January, February," he said. "It's hard to say where we'll be in November because it's right now, it's perhaps."

Pfizer vaccines and Moderna yet offer high efficiency rates up to six months, the longest they have been tested so far. On April 1, Pfizer shared a study that found his vaccine isalways 91% effective Six months after vaccination. And a study of April 6 published inNew England Journal of Medicineconcluded that the moderna vaccine is 94%effective after six months.
