"Information is not yet available about potential long-term health outcomes."
For example, one could question the potential for autoimmune conditions due to the way the mRNA vaccine works and how the immune system typically targets multiple proteins on the cell. There's no data or studies our there about this longterm possibility or even the incidence of autoimmune antibodies produced by vaccination. This likely isn't a problem for the elderly since it can take years or decades to present/progress, and their value proposition is different than for younger people. It starts to get more questionable as the value proposition changes dramatically in the youngest age groups. The question of vaccinating one's child for covid is certainly a topic with a diverse set of opinions and very little data to perform a thorough longterm cost/benefit analysis.
We already know Covid can cause autoimmune issues in some patients, so are you saying the effect you describe is just a subset of these, or different?
So all I'm saying is that the value proposition for an individual is based on the risks associated with vaccination or infection, and that the decision for people in age groups with the lowest known (short term) risks associated with infection have lower known benefits putting more emphasis on the unknown (longer term) risks or benefits. So for someone over 70 with about a 5% IFR, it's easy to say there is more benefit than risk because it's easy to see if a serious side effect is happening at a 5% rate or higher and the time horizon for longterm issues developing is limited by natural lifespan. With the quality of the VAERS data and the much longer time horizon, it's more difficult to discern a benefit for someone with an IFR of .002%. Of course we can't even look at the rates of many of the side effects to compare something other than IFR because the data data quality doesn't allow for that level of sensitivity.
Edit: why downvote?
Natural immunity is a thing, just like it always has been. I've heard all of the arguments about why nobody wants to widely acknowledge it, but I just can't agree with them.
Some chance of high probability of damages, vs full chance of low probability of damages.
This is why numbers are important... Fuzzy equation members like 'some', 'high' and 'low' are inadequate for this decision making.
Chances of infection given behavioural patterns, to be defined, × probability of damages post-infection, given demographics etc., to be defined¹
vs
100% for the chance of vaccination, × probability of damages post-vaccine (post 1 week, post 1 month, post 3 months etc.), given demographics etc., to be defined.
Probably you meant that according to available data, the probability of damages post-vaccine seem very low. Some people are concerned because those numbers do not seem to match the anecdotal they have around, so they would like to have better data - because some possible consequences are much more than nuisances. I say, if some entity kept an active monitoring ongoing, of the adverse side effects, much stronger reassurances - or less hesitance owing to confusion - could be given. I could only find passive monitoring around - USA, Europe, Australia, Canada etc.
¹The vagueness is such that in the context of this line, the last article I read mentioned values between 2.3% and 40%.
