The tweet you cite notes that only 18 people are hospitalized in Iceland. Adjusted for population, the US has over 4x as many hospitalizations. This is a huge success and 100% due to the high vaccination rates. Iceland was able to achieve this voluntarily. The US cannot.
That again has nothing to do with my argument, which is about the risk that being unvaccinated poses to others. If you are equally likely to be exposed to COVID if many are unvaccinated as if many are vaccinated, then you can't argue that other people deciding to not get vaccinated puts you at any additional risk.
> If you are equally likely to be exposed to COVID if many are unvaccinated as if many are vaccinated
That’s not true. According to data YOU provided, unvaccinated people are more than 2x more likely to be infected than vaccinated. Less vaccination leads to more infections and more hospitalizations.
But vaccinated people transmit the virus at a sufficiently high rate to prevent herd immunity from being established.
Without herd immunity, the virus will propagate, even if it's at a slower rate, making it inevitable that every one is eventually exposed to the virus.
