But if I had to guess, you're probably pro-MMR-2 (as am I), so the question is what epistemology permits that view?
For COVID-19 we are still guessing at most of this, hopefully the long term effects are not too bad and those effects of contracting the disease will get reduced over time.
But I would definitely not rule out some shocker long term effect at this stage that we are unaware of, especially not when taking into account developing organisms such as children, where effects can stay hidden for a long time.
There are some things we don't have high certainty on, but our epistemology would be faulty if we ignored how other coronaviruses behave, just like it would be faulty if we ignored how other attenuated viruses behave when we examine if MMR-2 will cause instadeath at age 60.
