How are you at extreme risk from an unvaccinated individual? For starters, virtually none of the unvaccinated have Covid (just like the vaccinated).
Secondly, how are you at extreme risk, if your belief in your own vaccination is so strong? If you are at extreme risk from being masked up and standing a couple of metres from an unvaccinated citizen, then what good does your vaccination do? Are you telling me that before vaccinations were in circulation, you managed to safely navigate your way through shops and streets without contracting covid, but now that 90% of the population is vaccinated you are in grave danger? Please explain how you are at extreme risk in this context.
