Some people have to go on blood thinners due to the covid shot. It’s rare, and most people should get their shot, but there are risks involved.
I work in a pharmacy and I’ve personally filled medications for about 5 people who said they are on blood thinners from getting a covid shot.
When I started college 15 years ago tuition for me was $7,000 per year. When I finished 4 years later, it was $12,000 per year. Things going up is normal. Things costing almost double within a few years is not.
