Deskripsi
The authors study a cohort of healthcare workers in India who received two doses of the ChAdOx-1-nCoV19 vaccine during the Delta wave. Using serological data, they infer that 25% of the cohort were infected within 60 days of vaccination, although there were no severe infections leading to hospitalisations.
