Actually the long term risk of the covid-19 vaccines is well understood. You will not get a side effect from the vaccines in a year from now. For all of the vaccines created for any disease, the longest recorded period between taking the vaccine and side effects presenting is 6 weeks. 3.1 billion people are fully vaccinated for covid-19, many of them have been for longer than 6 weeks.

In Norway, some children developed narcolepsy after being vaccinated with Pandemrix. The average time from vaccine (or influensa) until developing narcolepsy was 8 months.

There are possible severe negative effects due to vaccination, even if there are zero medical side effects. Herd vulnerability could cause widespread harm - there is a monoculture of immune responses and monocultures have vulnerabilities. I agree it's unlikely to have severe long term downsides, and the short-term gains are very significant. Note that I'm mostly pro vaccination.

I understand what well understood means but typically that also involves long term human clinical trials, and for a good reason.
