We compared (i) the incidence of first-registered childhood asthma based on hospital contacts and drug prescriptions and (ii) the incidence of severe asthma defined as acute hospital contacts for childhood asthma between the ages of 15 and 48 months among children whose last received vaccine was three doses of DTaP-IPV-Hib and then MMR with children whose last received vaccine was three doses of DTaP-IPV-Hib.RESULTS: For boys, following the recommended vaccine schedule of MMR after DTaP-IPV-Hib3 compared with DTaP-IPV-Hib3 as the last received vaccine, MMR was associated with 8.1 (95{\%} confidence interval 3.9-12.3) fewer childhood asthma cases per 1000 boys, corresponding to 10{\%} (5-15{\%}) reduction in the cumulative incidence of childhood asthma. MMR, when given last, was also associated with 16.3 (95{\%} confidence interval 12.7-20.0) fewer acute hospital admissions for childhood asthma per 1000 boys, corresponding to a 27{\%} (22-31{\%}) reduction in the cumulative incidence. No associations were seen for girls.CONCLUSION: MMR may have a protective effect against childhood asthma for boys. This calls for an understanding of whether non-specific effects of vaccines can be used to optimize our vaccine programmes.",
