Who is brushing off reports on VAERS? VAERS numbers are publicly available. There are certain time requirements for different types of reactions (e.g. anaphylaxis would have to happen within 2 days of receiving the vaccine but myocarditis they consider claims up to weeks later) but anything negative happening within a couple days after vaccination would be accepted by VAERS. I hardly trust facebook comments as a source. I can say that hundreds of millions of people have been vaccinated including very many that I know and I have yet to personally hear of any unexpected negative reactions. I'll trust that over anonymous comments on the internet. Of course I realize to you, this is also an anonymous comment on the internet :).

You can also look at it this way too... In the last week in the U.S., 750,000 doses of the vaccine were given. Statistically speaking, about 128 of those people would die of other causes. So statistically speaking, with hundreds of millions of people getting two doses of a vaccine, there are going to be thousands that die coincidentally within a day or two of getting the vaccine. If you don't realize that and you hear something like the following statement: "So far, 2,000 people have died within 2 days of receiving the COVID vaccine" it is going to sound horrifying when it is really meaningless. Now many of those will be people who are already knowingly sick or die in some way obviously unrelated to vaccination but there will be some number of them where the death was unexpected and might make someone suspicious but still had nothing to do with vaccination. I'd have to work a whole lot harder to figure out a ballpark for that number though...
