In Finland, the national vaccination program is implemented at child health clinics and by school nurses.

The most common reactions to vaccines include topical reactions around the injection site:

  • redness
  • burning
  • swelling
  • pain


    Allergic reactions are rare. Symptoms are typically skin symptoms including urticaria, redness, burning, swelling and rash.

      Typical reactions to different vaccines


    BCG (tuberculosis)

    • A discharging ulcer (blister) appears at the site of the injection and dries in a few weeks. The reaction confirms that the vaccination has been successful. 


    MPR (measles, mumps and rubella)

    • irritability, fever after 7 to 12 days of the injection 


    PDT (DTwP) (pertussis (whooping cough), diphteria, tetanus) 

    • tenderness at the injection site, fever a couple of days after the injection


    Polio (IPV) 

    • some children may develop a mild fever


    Hib (haemophilus influenza bacteria) 

    • typically no reactions


    Td (tetanus, diphteria) 

    • typically no reactions


    Alleviate the symptoms by giving your child antipyretics and/or analgesics. If the symptoms are unclear or severe, contact the child health clinic or local health center.
