EU regulator clears Pfizer-BioNTech’s tweaked COVID booster

LONDON (AP) — The European Medicines Agency has recommended the authorization of a tweaked booster dose of the Pfizer-BioNTech coronavirus vaccine that includes protection against two of the latest versions of omicron, as countries look to bolster their immunization programs ahead of winter. The EU regulator said Monday that laboratory studies suggest the combination vaccine — which targets both the original COVID-19 virus as well as the omicron subvariants BA.4 and BA.5 — should trigger an effective immune response. The vaccine is expected to be as safe as the original version, but the agency will continue to track its rollout globally since the data is limited.
