1. After three days of COVID-19 vaccination, you can do strenuous exercise. Try to rest within three days after vaccination in COVID-19, drink plenty of water at the same time, and don't stay up late to ensure adequate sleep and recover your strength. Do not take a bath on the day of injection to prevent infection at the injection site.

2. After injection, if you have dizziness, nausea, fever and other symptoms, you should go to the hospital in time for symptomatic treatment. The symptoms of most patients can be effectively alleviated. Don't drink alcohol for one week after vaccination in COVID-19.
