What are the side effects of immunisation?
Modern vaccines are extremely safe and effective. However, minor side effects have been reported, on occasion, for all vaccines. Mild reactions are commonly associated with some vaccines and should be expected.
These include pain and redness at the injection site, and occasionally a mild fever or rash. Paracetamol is recommended with some vaccines to minimise the symptoms.
While these symptoms may be painful or irritating at the time, most people consider the benefits of immunisation outweigh the inconvenience or risk of the relevant disease.
Very rarely, vaccines can cause serious side effects. This is usually due to an allergic reaction to a component of the vaccine. If you or a member of your family complains of feeling very sick, a headache, breathing difficulties or severe swelling at the vaccination site, a doctor or other medical professional should be consulted immediately
