Getting COVID doesn’t protect you from getting it again. While a lot of folks believe that catching it does protect you, there is a growing body of evidence that it does not. I recently helped write a peer reviewed analysis in Nature Communications Biology adding to that pile.

Omicron, in particular, reinfects people who had non-omicron variants more often than other variants.
You can ALSO catch omicron more than once. 
Even worse, Omicron reinfection occurs over an even shorter time frame. In some cases, only a few weeks!
We were able to get these answers because of the unprecedented level of worldwide scientific collaboration aimed at capturing viral sequences from infected individuals to build a public-facing database. Unfortunately, our ability to measure and quantify the viral spread is evaporating due to decreased funding & ability to continuously sequence patient samples. Better records could also answer more questions.
The "vaccines" created the Variants we agree on this right?
Many of the variants existed before the vaccines, so NOPE! 🤣
Thats a fundamental misunderstanding of how the biology works. You could argue that vaccines helped put environmental pressures to help omicron, but first versions likely developed absent a vaccine prevalent in the local environment. Not enough people took the vaccine to make that case, imo...
That said, I'm not aware of anyone who has done that analysis but I would be interested in reading it. #[2]
