One in four people experience mild side effects from Covishield vaccine: Lancet study

Systemic effects included headache, fatigue, chills and shiver, diarrhoea, fever, arthralgia, myalgia, and nausea.

One in four people experience mild, short lived systemic side effects after receiving the COVID-19 preventive by Oxford-AstraZeneca (ChAdOx1 nCoV-19) vaccine — known as Covishield in India — with headache, fatigue and tenderness the most common symptoms, published in the Lancet Infectious Diseases journal. The researchers from King's College London in the U.K. also found that most systemic side effects — meaning side effects excluding where the injection took place — peaked within the first 24 hours following vaccination and usually lasted 1-2 days. Systemic effects included headache, fatigue, chills and shiver, diarrhoea, fever, arthralgia, myalgia, and nausea. Local side effects — meaning side effects where the injection took place in the arm — included pain at the site of injection, swelling, tenderness, redness, itch, warmth and swollen armpit glands.
