Correct. It's inconvenient for the current narrative of getting absolutely everyone vaccinated with a spike protein from a single variant, but the best immunity currently available is naturally-obtained.

Also, mostly unrelated, but the word "sin" has little to do with theism, though maybe that's where it's most commonly used. For example, in archery, a miss is called a "sin". I think it's apt for this concept.
