Coronavirus vaccines: Covaxin vs. Covishield vs. Sputnik V; what we know so far about their possible side-effects

Developed by the Gameleya National Centre of Epidemiology and Microbiology, Russia, Sputnik V was one of the first registered coronavirus vaccines authorized for use globally. The viral vector vaccine works by triggering antibody production and hence, causes routine inflammatory reactions, most of which are mild in nature.

According to a Lancet study published in February 2021, the most common side-effects of the vaccine include:



-Pain at the injection site

-Flu-like illness

Serious side effects, or adverse reactions haven’t been observed yet. As per clinical studies, there have been incidents related to hypertension, hemorrhagic stroke, thrombosis, but none of them was found to be related to the vaccine injection.
