(ANSA) - ROME, JANUARY 25 - The hypothesis of delaying the injection of the second dose of vaccines against Covid-19, considered by some to widen the audience of vaccinated people, "causes concern. There is no full effect until the second dose, and if you allow less than optimal efficacy, you risk selecting new mutations.
It may not happen, but it is risky. "
This was stated by Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, during the Davos Agenda 2021. (ANSA).
