Where are you facts to back up that statement?
For the unvaccinated, the risk of getting reinfected both with the same variant or with different ones is higher than for the vaccinated.
"Someone who's unvaccinated would have some immunity, against the same variant but you would be much more likely to be infected with a different variant."

While some (unlucky) individuals have become reinfected within a short time frame (less than 90 days), this appears to be uncommon and related to being young and mostly unvaccinated.The bottom line is it will be hard to outrun becoming infected or reinfected with a COVID variant in the years to come.
We can't do much about the evolution of the virus or our own immune systems, but we can dramatically reduce the risk of severe infection in ourselves (and our loved ones) and disruption to our lives, by staying up to date with vaccinations and following simple infection-control practices.

If you are unvaccinated, that also increases your risk of catching Covid again. According to data from the ONS, people who were unvaccinated were more than twice as likely to catch Covid a second time, compared to people who were fully vaccinated 14 to 89 days ago.
