Here’s a hot take: I have no problem with people being excommunicated for speaking out against getting immunized for COVID-19.
Whatever health concerns you may have over the three vaccines, it should be abundantly clear that it’s still a better choice than to not get vaccinated. Not only will getting vaccinated protect yourself, but it will also protect those around you. It’s pure gayvah to talk about vaccinations and other COVID protective measures as “personal choice”. No, you’re elderly neighbor isn’t choosing to have you spit your diseased breath into her face because you wanted to say Gut Shabbos.
