Sara Y. Tartof et al.: BNT162b2 vaccine effectiveness against SARS-CoV-2 omicron BA.4 and BA.5, in: The Lancet. Infectious Diseases Volume 22 (December 2022) Issue 12, pp. 1663-1665, online in: https://doi.org/10.1016/S1473-3099(22)00692-2.

Booster vaccination (third or fourth dose) did provide protection against BA.4/5, but this […]
