A recent study on the duration of the protection provided by the AstraZeneca vaccines (Covishield, in case of India) - published in the leading medical journal, Lancet, provides, as under:
"We found [very significantly and, that too, at accelerating rates] waning vaccine protection of ChAdOx1 nCoV-19 [i.e. AstraZeneca vaccine] against COVID-19 hospital admissions and deaths in both Scotland and Brazil, this becoming evident within three months of the second vaccine dose [emphasis added].
