According to foreign media, Pfizer CEO Albert Bourla said two doses of the company’s vaccine may not provide strong protection against infection from the omicron Covid variant, ,and the original shots have also lost some of their efficacy.

    Bourla said omicron is a more difficult target than previous variants. Omicron, which has dozens of mutations, can evade some of the protection provided by Pfizer’s original two shots.

    Real-world data from the United Kingdom has found that two vaccine doses are 52% effective at preventing hospitalization 25 weeks after receiving the second shot, according to data from the U.K. Health Security Agency.
