My mental model of this (and I'm not a medical expert) is that (a) for a given amount of spike protein, the immune response is similar, whether the protein originates from the vaccine or the actual virus, but (b) since the vaccine is lacking the actual health threatening properties of the virus, you can expose people to massive doses of it without incurring much risk.

My place employment had almost 280 people get vaccinated (myself included). On the second dose well over 50 percent came down with flu like symptoms about 12 hours later. I was sick for 3 days and my wife was sick for 2.

  Would be curious on this forum on how many people got sick from Moderna.

30 percent+ have significant side effects on the second dose. This is more significant in people in their early 20's.

My wife and I are in our 40s. I had a really sore arm (like, the whole arm, not the injection site) and we were both tired for a day afterwards.
