There were many incidents of serious effects linked to those vaccines, but there's no point in getting into it again.
There's a reason that the National Vaccine Injury Compensation Program exists and a reason why the courts have awarded upwards of 5 billion dollars. I'm sure you'll claim that none of those involved serious injuries though.
Here's what it comes down to. You trust the Covid vaccines because
"Tens of thousands of people tested over about a year is enough for the various worldwide health organizations to clear it and enough for me."
Problem is, those tests tell us nothing about potential longterm effects. Aside from that, there WERE complications in test groups.
Also, some of those trusted experts of yours like Fauci have (as expected) been outed as corrupt, lying frauds.
Fauci hasn’t been exposed as a corrupt lying fraud, though. For instance any sane and reasonable reading of his emails wouldn’t approach that conclusion.
Anyway, the experts I’m talking about are the researchers and scientists who work in the field and have been educated and trained specifically for this purpose. They inform the decisions made by policy makers and leaders.
Sure, we don’t know the long term effects. What we do know is that the virus left unchecked would kill millions upon millions of healthy people worldwide. The longer we go without a vaccine, the more people it would kill and the harder it would be to contain and eventually eradicate. We can’t wait 5 years to ensure a highly likely safe vaccine is 1,000,000% safe.
