Notably, people who recovered from COVID-19 and therefore likely have some level of natural immunity are considered unvaccinated by the CDC. Studies show unvaccinated COVID-19 survivors are more than twice as likely to be reinfected by the virus than those who are fully vaccinated.
Just FYI, I looked up the study and the media title for it is really misleading, what the study shows is:
Those whom were not vaccinated and got COVID were 2.34x as likely to get COVID again compared to those whom were not vaccinated and got COVID then got vaccinated.
The study does so by comparing people whom had COVID in 2020, got vaccinated, and whether they had a second breakthrough case within a certain date range. So a few things to note about this:
1: The people whom had natural immunity did not have Delta previously but had Alpha
2: This does not compare natural immunity to the vaccine, it compares natural immunity + vaccine to natural immunity
3: The natural immunity in this case would be considerably old, since it is comparing COVID 2020 cases to people infected up through midpoint of 2021
I think it's probably intuitively obvious that natural immunity + a vaccine works better than natural immunity. I'm not sure what else I would take from this study though.
and confirming what we already knew:
In August, the most recent full month for which data is available, unvaccinated people were more than 6 times more likely to test positive for COVID-19 than their fully vaccinated peers were ― and more than 11 times more likely to die from it
While also true, I don't think you are setting the context of this data reasonably vs the first sentence you make as there is a strong implication that natural immunity people will have these statistics, and I don't think that is true. Particularly if your natural immunity is in the Delta variant era.
If your natural immunity was from the Alpha variant era (2020 or earlier) then your protection has likely waned, but much like with vaccines, I don't think we really have a robust idea about how much. Also, people develop antibodies very differently from natural infection so there will be far more variance individually which is another argument to why everyone should just get vaccinated anyway. Some people may have robust immune responses to natural infection and others won't. You really don't know which group you are in without a number of tests which are more invasive than just getting the vaccine anyway.
Even if you have Delta immunity, I'd get vaccinated. It can only benefit you. I'd love to see the numbers on it to know how it fairs vs the vaccine immunity alone thing, but that is more of a curiosity for me. My guess is Delta based immunity is actually stronger than the vaccine and the CDC probably doesn't want to post that because they don't want to muddy the issue and have people not get vaccinated. (I'd imagine these numbers should be commonly available for research even without a specific study but just data mining).
