Pfizer CEO Albert Bourla said Wednesday that people might need a fourth Covid-19 shot sooner than expected due to omicron.
Bourla noted that a preliminary study by the company was based on a synthetic, lab-created copy of the variant and more data is needed from tests against the real virus. Those real-world results will be more accurate and are expected in the next two weeks, the Pfizer CEO said.
"When we see real-world data, will determine if the omicron is well covered by the third dose and for how long. And the second point, I think we will need a fourth dose," Bourla told CNBC's "Bourla previously projected that a fourth shot would be needed 12 months after the third dose. "With omicron we need to wait and see because we have very little information. We may need it faster," he said.
The Pfizer CEO said what's most important right now is to roll out third doses for the winter. Public health officials are worried about a spike in"A third dose will give very good protection I believe," Bourla said. He also said that treatments such as Pfizer's oral antiviral pill, Paxlovid, will help prevent hospitalizations and control Covid during the winter.
