If you could enlighten us all with what is laughable that would be constructive. If not I’ll put it down to you don’t like the comment and have nothing of value to add so decide to make a snide remark
It is not that I don't like the comment. It is that it is a ridiculous comment which makes no sensible point at all. You said "I don’t believe there was a vaccination program for Spanish flu in the early 1900’s which was more deadly than COVID.". So what? Does that mean that we should not try to prevent or treat illness that are not as bad as Spanish flu?
By the same bizarre logic, presumably boats should not need lifeboats or other safety equipment the The Titanic didn't have.
Back in the real world, though, things have moved on a bit from the era where many children died in infancy and average life expectancy was in the late 50s.
The most telling comment is the very last one, about Covid not being fatal to most. That is true as far as it goes, but Covid is not just about death, and the biggest effects could well come from some of the non-fatal stuff that you do not even mention. Sticking to fatal outcomes is common among Covid-deniers. Nor is Covid vaccination just about
your personal risk.
And don't get me started on your blather about the testing of, or long term effects of, Covid vaccination.
