> Before 2020, no mRNA technology platform (drug or vaccine) had been authorized for use in humans, so there was a risk of unknown effects.[79] The 2020 COVID-19 pandemic required faster production capability of mRNA vaccines, made them attractive to national health organisations, and led to debate about the type of initial authorization mRNA vaccines should get (including emergency use authorization or expanded access authorization) after the eight-week period of post-final human trials.
That risk of unknown effects was still there even when it got authorized for emergency use. Has it changed yet? Like... there was a vaccine based on old tech that has been used in humans for decades without side-effects that caused narcolepsy a year or two later, and we got lucky to have been able to make the association. It is not really only about what tech it uses, apparently.
