I can't verify all these reports - but there are a lot of them.

It's easy to understand the motivations for downplaying adverse effects from the vaccine - reduce vax-hesitancy, human nature to not want to be wrong, zillions of dollars in profits for medico-industry, desire to vilify others, fear of being vilified/losing your job - but hard to think of why people would make up stories about adverse effects. In some cases it cost them their jobs.

The common themes seem to be:

brain fog - headaches/malaise/weakness
flare-ups of joint pain
skin rashes
personality changes (aggression)
menstrual problems
difficulty breathing
kidney stones
heart problems
blood clots
sudden death in elderly

The majority of the whistleblowers report that doctors are angrily censoring links between adverse effects and the vaccines.
