It is amazing that for all of the focus on breakthrough cases of people who have been vaccinated. there is very little attention paid to folks who got COVID in 2020, then got COVID again.

(4,400 posts)antibodies disappear or don't work? Does this explain long-haul symptoms? Mutated variants escape recognition of even the basic novel virus features on which the vaccine was made? I'm already 6 months out from "full vaccination" Pfizer status and at risk by age group and previous medical conditions though not serious enough to be considered immunocompromised. I do understand that for about 5%, the vaccine will not be effective and protection reduces somewhat over time so "break-through" isn't surprising; hence the need to maintain hygienic protocols.
SARS-CoV2 is an automatic "gain of function" natural bio-weapon?

(17,390 posts)I think the answer is no, since they are comparing folks who have been infected who were vaccinated versus not, and the question is reinfection.

Turns out that's not entirely true. On Friday, the Centers for Disease Control and Prevention released a study reporting that individuals who've had COVID are twice as likely to get reinfected.

Dr. Henrich has been studying the long term impacts of COVID-19 and says the immune response from natural infection is not as high. "Both antibody responses and cellular immune responses or for example T-cells that recognize SARS-CoV-2 infection can persist for months. Eight to 12 months after natural infection and most likely after vaccination. What we don't fully understand is how protected those immune responses are longer term overtime," said Dr. Henrich.
In the CDC study, residents who were infected with COVID in 2020 experienced a reinfection between May and June of 2021. That's the same time the Delta variant intensified across the country.
