The effect of season on the antibody response after Hepatitis B (HB), Measles and Rubella vaccination in humans was investigated. In view of the immunosuppressive effects of ultraviolet radiation (UVR), especially the B-waveband (UVB), it was hypothesised that a lower antibody response after vaccination procedures that were started in summer might be detectable. IgG assessments and dates of vaccination were available 1. from a survey on the formation of anti-HB antibodies (anti-HBs) after vaccination to HB among paramedical students in Utrecht, 2. from an experimental study on the effect of artificial UVB on the immune response to HB vaccine, and 3. from a cross-sectional serosurveillance study on various vaccinations in a random sample of the Dutch population. In the surveys on HB the antibody formation in the course of a standard HB vaccination procedure (Engerix-B, SB; standard 0, 1, 6 months) was analysed by season of first vaccine injection. In the serosurveillance study the anti-Measles and anti-Rubella IgG titers in children who were aged 2-7 years at the time of the survey, and who had received their Mumps-, Measles-, Rubella-vaccination only once (MMR-1, at 14 months of age) were analysed by age and season. The data from the survey among paramedical students indicated a slightly retarded antibody response during vaccinations that were started in a sunny season. However, this finding was not consistently found after breaking down the data by calendar year and at the end of the procedure equal levels of anti-HBs were found. In the other surveys no seasonal influences on the formation of antibodies could be established. These data support the hypothesis of a reduced immunoprotection due to high ambient UVR during sunny season only to a limited extent. The study design may have been too crude with respect to both personal differences in exposure and susceptibility to UVR and the immune responses following immunisation for demonstrating the postulated effect of UVR. An advice for the general population to avoid the starting of a vaccination procedure during sunny season appears to be premature at present.
