Cutaneous adverse reactions from 35,229 doses of Sinovac and AstraZeneca COVID-19 vaccination: a prospective cohort study in healthcare workers.

Cutaneous adverse reaction (CARs) from mRNA-based COVID-19 vaccines have been reported in the literature.[1, 2] On the contrary, information regarding Sinovac (CoronaVac), (SV) inactivated virus and adenoviral vector AstraZeneca (ChAdOx1 nCoV-19), (AZ) vaccines remains scarce. We have conducted this prospective cohort study to address this issue.
