Yes. Serious complications of immunisation are rare. However, mild fever and irritability are common, especially 6 to 12 hours after DPT immunisation. A mild fever, irritability and slight rash are common about a week after measles and MMR immunisation. These mild side effects can be treated with paracetamol (Panado) 6 hourly for 4 doses if needed (2.5 ml if under 1 year and 5 ml if 1 to 5 years). The benefits of immunisation are far greater than the risks. Therefore, as many infants as possible should be fully immunised.
There is no evidence that immunisation increases the risk of cot death.
