What If Most Vaccine Side Effects Go Unnoticed? A Worrying Hypothesis

The enormous progress made in public health over the last century is largely thought to be due to the gradual introduction of numerous vaccines, which have helped to control, if not eradicate, the most serious and common infectious diseases, particularly those affecting children. Due to its past successes, vaccination has become such a dominant public health strategy that discussing its potential drawbacks calmly within the scientific community is virtually impossible.At the same time, the public is becoming increasingly wary of vaccines, especially the latest mRNA-based vaccines, with social media spontaneously reporting a growing number of highly diverse adverse reactions. Given the unreliability of these reports, their extreme diversity, and the absence of proof of causality, it is extremely difficult to determine whether these are really adverse effects of vaccination or mere coincidences. Yet the incidence of chronic diseases is steadily increasing, from the most benign (allergies) to the most serious (neurodegenerative, aggressive cancers), including strictly individual perplexing ailments.In this article, without taking sides on the origin or even the reality of these health problems, I propose a theoretical hypothesis which, based on our current knowledge of immunology, could effectively call into question the generally accepted harmlessness of vaccination. According to this hypothesis, the extreme individuality of the immune response, coupled with the frequent occurrence of autoimmune reactions, could trigger extremely diverse “private” pathologies, whose frequencies of reproducibility might be too low to deduce causality.
