The public will need to to get a "second booster" shot of the Covid-19 vaccine "to protect against infection." That's according to Pfizer CEO Albert Bourla.
For Pfizer and Moderna, a second booster is actually the fourth shot: two initial shots that government officials now say were not spaced properly, and two booster shots.
In February, the Centers for Disease Control (CDC) published a study showing Pfizer-BioNTech and Moderna vaccine boosters waned after about four months. But the agency claims the jabs but still provided significant protection from hospitalizations during the Omicron surge.
On the other hand, relatively few unvaccinated people were hospitalized with Omicron, either.
According to Bourla's recent interview with CBS News.
The third dose of the Covid-19 vaccine provides protection from hospitalization and death, but it's not that good against infections and the protection is relatively short-lived. Many variants are coming. And Omicron was the first one that was able to evade in a skillful way the immune protection that we were giving. But also, in all that the duration of the protection, it doesn't last very long.”Albert Bourla, Pfizer CEO
Pfizer is currently preparing data for the Federal Drug Administration (FDA) about its argument for a fourth dose.
Bourla also recently told CNBC that Pfizer is developing a vaccine that will protect against all Covid-19 variants, including Omicron, for at least one year.
Pfizer expects to review data from trials on the "long-term" vaccine by the end of March.
Meantime, a growing body of evidence shows natural immunity from Covid infection is longer lasting and more effective than vaccines to date.
