“The vaccines are effective against all variants when taken in both doses.” It is the reassurance ofMom, European Medicines Authority, in the face of a Europe frightened by the Delta strain. Data on people infected after the vaccine confirm this observation for now. A small number of vaccinated people – between 5% and 10% – contract the virus despite the injection, almost always before completing the cycle with the second dose.
