Like all medicines, vaccines can cause side effects. Most are mild and short-term, and not everyone gets them.
Very common side effects include:
● pain and tenderness in the arm where you had your injection, which tends to be worst after 1-2 days
● feeling tired
● general aches, or mild, flu-like symptoms
Symptoms usually only last 2-3 days and normally less than a week. Resting and taking painkillers, such as paracetamol should help you feel better.
Don't let side effects put you off having the second dose, as you need that to get the best protection.
Although feeling feverish is not uncommon for two to three days, a high temperature for longer than a couple of days is unusual and may indicate you have Covid or another infection. If your symptoms don’t get better, or seem to get worse, or if you are concerned, seek advice by calling NHS 111.
Should I get it now?
Millions of people have now been vaccinated against Covid. The vaccine is the best defence against the virus, so the sooner you're vaccinated, the sooner you’ll begin to protect yourself and your community. Vaccinating as many people as possible should reduce the levels of local infections too.
Will it give me Covid?
You can’t catch Covid from the vaccine. It may take a few weeks for your body to build up protection against the virus, but it will reduce your chances of becoming seriously ill. You need to have both doses for maximum protection.
Has it been tested?
The approved vaccines have met strict standards of safety and quality. They have been tested on tens of thousands of volunteers in multiple clinical trials and given to millions of people. Reports of serious side effects have been extremely rare, but some vaccines may be recommended for people under 40.
