EDIT: My reply above was in regards to vaccines for those who already have caught covid and presumably have natural immunity, immunity that looks like it is better than vaccine immunity. The equation for those people to get the vaccine is different than the equation for the non-vaccinated.

I listed questions some people may have. I don't have all the answers. I consider that running numbers for stuff like this involves a certain amount of guesswork, things that can't be well qualified.

> I mean, by definition being sick is not being healthy. You'll need to expand this a bit for it to make sense.

I was thinking of the many healthy people who got very sick (collapsing, bedridden, etc) for a short time (24-36 hours) after getting the vaccine. Does that mean their immune system was already primed and went on the attack? I've heard that can cause autoimmune reactions - the immune system attacking something that is part of the body accidentally (collateral damage).

> How can you quantify and qualify this risk?

I did the best I could for myself, trying to prioritize. I may be more comfortable than most working with ambiguity. The biggest factors obviously were known covid risks based my age and health, numbers from the vaccine trials (which I wish were more easily available) and an awareness of all these other less quantifiable things (a lot of reading and learning).

EDIT: If I had confirmation that I already had covid my calculations would have changed. I don't know by how much, to be honest! I certainly would have felt substantially less need to get a vaccination, and it looks like science is bearing that out. If I have to deal with a lot of unknowns for a 1 in 10k improvement in my odds after I already have the better natural immunity, I might rather not deal with the unknowns.

There were some adjustments made by authorities, like those around the AZ risk for young women, because the odds didn't favor that treatment for those people. This is all new, and still developing. The number of breakthrough infections in Israel is interesting, for example. Hopefully that doesn't lead to any kind of weird/bad evolution of the virus.

> auto-immune reactions

You are certainly correct that covid includes the risk of autoimmune reactions, also! And other risks. As time goes on we have better numbers for covid, and better numbers for the vaccines. I made my decision with the best numbers that I could find at the time.

On the topic of vaccine autoimmune reactions in general, I looked into it and it was difficult to find good data, it looked like the immune system was complicated enough that science doesn't have stuff like that all figured out.

> Again, you're not saying who it is that doesn't do a great job

I'm not saying that I have the answers. These are questions that some vaccine-hesitant people have. Ideally the experts would do a good job of answering them, including admitting where they don't have good answers. Lots of people are resistant to being forced into something through social/financial/government pressure.

I personally assume this is going to reverberate around the world a bit more, waves of decreasing intensity until most of us have been exposed, becoming endemic and not so big a deal (like the other coronaviruses that are endemic). It might be hard to know how much of anything we did made a difference.
