For all vaccine-preventable diseases the risk of complications with the natural infections is very much greater than the risk of a serious adverse reaction following the vaccine.

Serious allergic reactions are a very rare possibility with any vaccine.  Medicines and their possible side effects can affect individual people in
different ways.

Reactions to an immunisation can vary depending on which vaccine(s) have been given.  For any information on the side effects that are known to be associated with the vaccine(s) please refer to the manufacturers information on individual vaccine pages.
