The present review summarizes data on neurological adverse events following vaccination in the relation to intensity, time of onset, taking into account the immunological and non-immunological mechanisms. The authors described the physiological development of the immune system and the possible immune system responses following vaccination. Toxic property of thimerosal – a mercury-containing preservative used in some vaccines was presented. The neurological complications after vaccination were described. The role of vaccination in the natural course of infectious diseases and the current immunizations schedule in Poland was discussed.
Despite the assurances of the necessity and safety of vaccinations, there are more and more questions and doubts, which both physicians and parents are waiting to be clarified. This paper describes several aspects of the immunization program of children. It includes: the physiological development of the immune system, the immunization schedule adopted in Poland in comparison with other countries, adverse reactions and complications following vaccination described in scientific publications, the natural course of infectious diseases in conjunction with the vaccination programs implemented and the problem of reporting adverse reactions following vaccination by medical personnel and parents. The proposal for changes in vaccination in Poland cited at the end of this paper is, according to the authors, part of the answer to the concerns and doubts. A second part would be extensive neuro-immunological research confirming or excluding the relationship of vaccines with the reported adverse events (early, late/long-term) and chronic diseases whose upward trend has been observed in recent decades in children.
It seems that it would be worthwhile to apply the precautionary principle – the ethical principle (from 1988) according to which if there is a probable, although poorly known, risk of adverse effects of new technology, it is better not to implement it rather than risk uncertain but potentially very harmful consequences.
