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.
