> the rate of discovered issues being hard to measure because it is almost background noise Efficacy of post-vaccine follow-up and reporting may change with time, and hopefully will. The problem is that there is no meticulous data gathering from all vaccinated persons. Reports of issues are voluntary in most cases and in some cases institutions are not even notified by the vaccinated persons. According to one study of VAERS frmo 2020, a passive reporting system, the real amount of issues is underreported; depending on the effect, the reporting efficacy is somewhere between 12-76% [1]. This is not a great system and because of that data gathering is not as fast as could be. [1] https://pubmed.ncbi.nlm.nih.gov/33039207/ https://pubmed.ncbi.nlm.nih.gov/33039207/
