Hi Sabine: At the regional conference of the GBS (NZ) Support Group today there was a very good lecture from Dr Kilfoyle on just his topic and some lively follow-up discussion. Over 1.1 billion doses of COVID vaccine have been administered so far and there have been only 2 cases of GBS occurring in the 6 weeks following the vaccination, neither of which had had previous GBS. The expected number of GBS cases that we would expect from chance alone would be about 1500 so we can say confidently that the vaccine does not trigger GBS. The vaccine should not affect your husband any differently from any normal person getting the vaccine. Gareth
