He then had a recurrent episode 1 week after the booster doses of his quadrivalent diphtheria-tetanus-pertussis-polio, pneumococcal and meningococcal group C vaccines at 5 years of age. On both the occasions he required hospitalisation and treatment with intravenous immunoglobulin. He received other vaccines, before and in between, without any adverse events. Future vaccines are to be determined on an individual risk-benefit basis and he will be reviewed at the age of 11 when his next routine immunisations are due.
