Covid-19 Vaccination - ADRs

COVID Special

Adverse reactions ( ADRs), commonly called side effects, to vaccines are usually mild and go away a few days after the vaccination. Find out what you should do when faced with some of the situations that may arise.

What to expect after getting the vaccine?

After getting the COVID-19 vaccine it is natural to have so-called adverse drug reactions (ADRs), commonly called side effects - but have no fear - this means that our immune system is building up defences against COVID-19. Some of the most common ADRs are pain and swelling at the vaccine  site, fever, chills, tiredness and headache.

  • Apply ice or a cold damp cloth to the swollen area several times a day for short periods. 
  • Avoid using or straining the arm where the vaccine was administered.

2. General malaise and/or tiredness:

  • If you have a fever you may take a medicine to help lower your body temperature - ask your pharmacist for advice.
