"The Pfizer vaccine is highly active against the delta variant," Dolsten said in an interview. The FDA and CDC, in their joint statement, said: "We are prepared for booster doses if and when the science demonstrates that they are needed." He said multiple countries in Europe and elsewhere have already approached Pfizer to discuss booster doses, and some may begin administering them before a potential U.S. authorization. Pfizer's chief executive has said people will 'likely' need a third booster dose within 12 months and could need annual shots. It is already targeting production of 3 billion doses this year and 4 billion doses next year.
