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.
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.
How was it made so quickly?
The Covid vaccines have been developed, assessed and independently approved using the same processes that would normally be used to develop a vaccine. They have been through clinical trials involving tens of thousands of volunteers, a testing process which tells us they are safe and effective.
Which vaccine will I get?
You won’t be given a choice, and will be offered the vaccine which is being given on the day of your appointment and recommended for your age.
Currently, the Joint Committee for Vaccinations and Immunisations (JCVI) has advised that it is preferable for people under 40 to have a vaccine other than Oxford/AstraZeneca.
Pfizer or Moderna vaccines are mainly being offered to those aged under 40.
Adults aged 40 or over, and adults with health conditions that put them at increased risk from Covid infection, can continue to receive any of the available vaccines. For these groups, the benefits of the vaccine to protect against serious illness far outweigh any other risk.
