  • You should get the next needle as soon as possible
  • If you didn’t follow the routine immunization schedule a "catch-up" schedule will be recommended

What if I decide not to be immunized?

  • Choosing not to be immunized or delaying immunization puts you/your child at risk of getting sick with measles, mumps and rubella.  These vaccines are required by law (Immunization of School Pupils Act, 2014) for school attendance. Students who are not vaccinated may be suspended from school.

  • Had a bad reaction to a vaccine or an ingredient in the vaccine, had a serious reaction to neomycin
  • phenol red, porcine gelatine or have any other allergies*
  • Are pregnant
  • Take medications or have any diseases that lower the immune system or increase bleeding
  • Feel very sick
  • Had a vaccine within the last month
  • Received immune globulin or blood products in the last year
  • Plan to donate blood in the next 12 weeks

Is MMR vaccine safe?

Yes!  You may have no reaction or mild symptoms that include:

  • Redness, swelling,  and pain where the needle went in
  • Low fever
  • Children may become fussy or sleepier than usual;

These normal reactions usually last between 12 and 24 hours.  
Some children will have a rash and/or joint pain that last a few days.

When should I call my doctor?

Serious reactions after vaccination are very rare.  Get immediate medical help if you/your child have any unusual symptoms such as:

  • trouble breathing, swelling in your face/mouth and/or blotchy skin (hives)
  • fever above 40°C (104°F);
  • crying or fussing for more than 24 hours;
  • worsening swelling, redness, and/or pain where the needle went in;
  • unusual sleepiness (difficult to wake)

You know best.  If you notice anything that is not normal after a vaccination, check with your healthcare provider.
