The vaccine is not routinely given to everyone in Canada, just those in the high risk categories. Pneumococcal vaccine is effective in those over 2 years of age. Therefore, those with the risk factors identified should receive the immunization before they catch pneumococcal disease. For those people at highest risk for serious disease, at least two doses of pneumococcal vaccine may be necessary. Persons who have been previously vaccinated should consult their physicians to determine if this booster shot is recommended.
Any vaccine can cause side effects in some people.
About half of all people who get pneumococcal vaccine have a little swelling and pain in the arm where the shot was given. Less than 1 in 100 people have more severe side effects, like a fever or rash. Some people who get booster shots have stronger reactions, such as more swelling or a sore arm for a few days.
