Vaccine vs natural immunity, page-13

The downside of this strategy being, of course, that you need to contract the virus whilst unvaccinated. Recent data from NSW shows COVID is hospitalising 10%+ of those who become infected, it's not a small number.

People need to make their own decisions as to whether they want to expose themselves to increased risk of death and hospitalisation from COVID, or receive an annual type vaccination.

The study you have linked basically says that if the virus mutates enough, new vaccinations will be required. Nothing shocking there. However, if the virus does mutate further, natural immunity obtained via infection from previous forms of the virus will also be reduced.

The vaccines basically teach your immune system what to look for and fight against. I'd prefer my immune system to have a head start on this rather than allowing blind infection and hoping for the best.

Cheers!
