One dose of vaccine is not enough to protect against the Delta and Beta variants, new research suggests, and even people who have had Covid-19 should be immunized.

Risk of reinfection with Delta may be 46% greater than with the Alpha variant, national testing data finds

Found 2 after plugging in. Skimmed so hopefully these are the ones I read before lol Of course some are studies in lab and some are real world. Does natural immunity fade or is it the Alpha-Delta difference doing it.
My general thought based on other studies though, natural immunity seems to be not as good as vaccine as a whole, but more importantly double vax plus covid+ seems amazing in immunity response. So to me it's a no brainer there. Get vaccinated no matter what. Get the super immunity if you can! Especially while we're running booster trials. Get the best you can!
