That is misinformation. While there can be benefits to vaccination after infection, recovery from infection does produce durable cellular immunity in the vast majority of patients. Antibody levels always wane over time, but there's more to immunity than antibodies.

I encourage everyone eligible to protect themselves by getting vaccinated but the reasons to get a COVID-19 vaccine have really nothing to do with the reasons to get a shingles vaccine. Shingles is caused by the varicella herpesvirus which remains dormant in the body even after the acute infection has cleared. That virus works in a completely different way than SARS-CoV-2.

Given that I don't know anything about how antibodies and T-cells and all that jazz work and I don't plan on listening to a 2:40hr podcast to learn what some dude on the internet thinks about it, all I can say is that there appears to be research demonstrating that the COVID-19 vaccine has real benefit to people who already contracted the actual virus[0], which make's my government's advice that folks in that situation still get vaccinated[1] seem pretty reasonable.

Dr. Attia is very much within the medical mainstream. The CDC resources you linked are, frankly, for persuading ignorant people, and not really appropriate to a site devoted to satisfying intellectual curiosity. I'm also uncertain what exactly you're trying to convey by admitting total ignorance and blind faith in a US government agency. Is that supposed to convince curious people you have something interesting to say?

I believe it's important to consider the recommendations of experts as well as the evidence they claim warrants those recommendations. That's why I linked directly to both the recommendation itself (that's the second link, titled "FAQ"), as well as the evidence which (in my estimation) credibly backs it up (that's the first link, titled "Reduced Risk of Reinfection with SARS-CoV-2 After COVID-19 Vaccination — Kentucky, May–June 2021").

The podcast linked above is not "some dude on the internet". It is a panel discussion by several physicians including Dr. Monica Gandhi, one of the country's leading experts on infectious diseases. Definitely worth the time to listen if you want to understand what's really happening with the pandemic.

Nothing in my comment contradicted CDC guidelines.

I think I misread your post originally, and appreciate the correction. My apologies.

>The immunity can wane and the virus can mutate. Same reason you would get a shingles vaccine or a yearly flu shot.

aren't the current mrna vaccines based on the old 2019 variant of covid?

If you read exactly one additional sentence from my post you will see an acknowledgement of that very fact, as well as my justification for bringing up that line of reasoning in the first place. :)

I can understand if it mutates to the point of circumventing the original immunity and there's a new vaccine variant to address that specific mutation but as you yourself point out, that doesn't apply here, so I don't get it?
