The vaccine keys your immune system on a mostly unchanging part of the virus. It’s such a key part of the virus that for the virus to mutate that part it would be a dramatically different and less deadly mutation.
In an infection your body randomly keys on any of a large number of characteristics of the virus. Those almost certainly will be less lasting than the vaccine.
That’s why to get the vaccine.
- Siira 5y agoThis needs empirical evidence though. It’s a just-so story without that. Not that I disagree with the prior.
- anonymouse008 5y agoSo I guess my hesitation is, if my body has already been keyed by the original virus, had a terrible viral load (was positive for longer than I ever imagined), but very few symptoms... I’m fairly proud of my immune response and personally am wondering why I should take aim with a direct mRNA shot, feels unnecessary.
- ianai 5y agoHere’s a discussion with how it all works and relevant links (edit: though I wish there were more sources there. Reader will have to do some work themselves): https://news.ycombinator.com/item?id=27125871 https://news.ycombinator.com/item?id=27125871 There’s some positing that the vaccine could help or totally stop so-called long covid symptoms. My mom had some long covid symptoms and hasn’t since she got the vaccine. Also from the link, second exposures to infectious diseases seriously boost the immune systems ability to fight the disease. It’s like training your immune system once with the exposure and original infection then a second (and third time for Moderna and pfizer) time with the vaccines. In the mRNA vaccine case, they train on a particularly optimal characteristic.
- postalrat 5y agoMy guess is the vaccine is acting as a placebo for those with long term symptoms. I'm sure eventually we will know more.

- Vecr 5y agoOr the long term symptoms are mostly nocebos, and/or the only reason they are regarded as having one cause instead of many (as well as symptoms they would have gotten anyway) is that the person in question knows about "long COVID", or a combination of those and possibly even something that's really causally related.
