A large part of the world's population has received the coronavirus (COVID-19) vaccine, either one or two; some even have been inoculated with the booster shots. More than 10 billion doses of COVID-19 vaccines have been administered globally as of March 2022.
Some people have experienced the side effects of the Covid vaccines, usually mild and self-limiting. Fever, fatigue, headache, muscle pain, chills, diarrhoea and pain at the injection site are some of the common symptoms experienced by most people.
