Some are using this preprint to claim natural immunity is stronger than one from vaccines. Which, even if true, is irrelevant because natural immunity has a huge risk of killing you or giving you long Covid, unlike vaccines.
But this isn’t what it shows.

The Israeli standard for fully vaccinated is different from that and the rest of the world because Israel used only 3 weeks as the interval between the two doses, which we now know is too short. So their comparison between “fully vaccinated” and unvaccinated is invalid.
But this study shows me something more valuable: catching Covid twice is very rare: 37/14029=0.26%, ie natural immunity is 99.74% protective. Which is AWESOME news for eradicating Covid — hey, even if you don’t want to take the vaccine, no worries, Delta will inoculate you.
Another interesting observation is that even if you already did have Covid, an additional single dose of the vaccine can reduce your risk of catching it again in HALF (20 vs 37 without a vaccine).
