Vaccine boosters could be necessary as soon as September

Good to know.

The first Americans to be vaccinated against the coronavirus could require a third “booster” shot as early as September, the CEOs of Pfizer and Moderna told Axios.

Driving the news: “The data that I see coming, they are supporting the notion that likely there will be a need for a booster somewhere between eight and 12 months,” Pfizer CEO Albert Bourla said yesterday during an Axios event.

That means some Americans could need a booster as soon as September or October, he added.

State of play: Only time will tell how long protection from the first two vaccine doses will last, but there’s no evidence yet that it’s fading. Even if protection does begin to fade — which is common among vaccines — it won’t happen overnight.
