Purpose There have been speculations that increases in vaccinations have caused recent increases in wheezing lower respiratory disease during infancy. We assess possible associations between vaccines and incidence of wheezing in full‐term infants. Methods We conducted a matched case–control study of full‐term infants born into the Kaiser Permanente Northwest health plan during 1991–1994 and continuously enrolled for at least 12 months ( n = 1366 case–control pairs). Potential cases of wheeze were ascertained from medical care databases and verified by chart review. Vaccinations, demographic factors, and wheeze risk factors were abstracted from charts. Adjusted relative risks of first onset of wheeze during post‐vaccination exposure windows were estimated by conditional logistic regression. We also conducted case‐series analyses of wheeze onsets. Results We found no evidence that risk of wheeze during infancy is associated with recency of vaccination with whole‐cell pertussis (DTP), hepatitis b (HBV), Haemophilus influenzae type b (HIB), oral polio (OPV), or measles, mumps and rubella (MMR) vaccines. We also found no evidence that risk of first wheeze is associated with exposure to HBV or MMR. Conclusions Recent increases in wheezing during infancy do not appear to be related to increases in vaccinations of full‐term infants. Published in 2002 by John Wiley & Sons, Ltd.
