Coronavirus Vaccine: Commonly Asked Questions

Will the Vaccine have side effects?

  • Like all medicines, vaccines can cause side effects. Most of these are mild and short term, and not everyone gets them
  • If you have mild symtoms after the first dose, you should still have the second dose. Please report any more marked symptoms to your doctor
  • Although you may get some protection from the first dose, having the second dose will give you the best protection against the virus
  • Very common side effects include: 
  • Having a painful, heavy feeling and tenderness in the arm where you had your injection. This tends to be worst around 1-2 days after the vaccine
  • Tiredness
  • Headache
  • General aches, or mild flu like symptoms
  • About fever...although feeling feverish is not uncommon for two to three days, a high temperature is unusual and may indicate you have COVID-19 or another infection. You can rest and take the normal dose of paracetamol (follow the advice in the packaging) to help feel better. 

Symptoms following vaccination normally last less than a week. If your symptoms seem to get worse or if you are concerned. call NHS 111
