"Who are the unvaccinated hurting, exactly?"
It appears to me that a pandemic of the unvaccinated harms the unvaccinated.
"Those who cant get the vaccines"
Now, some people will point out that some can't get the vaccines. Except that ppl with HIV, GBS, autoimmune etc are all encouraged by the CDC to get the vaccine. Children under 12 have ridiculous low rates of harm from COVID. So the folks getting hurt by not being vaccinated are the ones who chose to be unvaccinated. (I have a fairly serious auto-immune disease and it's not obvious to me that I should get the vaccine. Some of the reported side-effects are triggering my auto-immune disease. I'm waiting for my annual appointment my specialist next month to talk about this)
"Herd immunity to end the pandemic"
Another objection is that the pandemic will not end, we will not reach herd immunity, unless we vaccinate x amount of people. Except that it's not obvious to me that pandemic will ever end - we'll just co-evolve with COVID to be less harmful. The reasons being:
1. We'll never vaccinate Afghanistan or Central Asia in general, South Saharan Africa, etc. so COVID will never go extinct [1]
2. COVID-19, being a coronavirus, will likely evolve quickly out of our vaccines' scope. Furthermore, variants bifurcate so even if we can make new vaccines quickly, there will be too many variants to have to target.
3. Given points 1. and 2., heard immunity for a given country appears to be futile attempt.
4. Quickly vaccinating everyone before COVID bifurcates too much appears to be a fools errand. Anyway, you'd make more progress vaccinating the third world than trying to convince reluctant young people in the first world. In the third world the vaccines would be far more effective at stopping COVID's bifurcation (since they have a lot of young people who could safely be inoculated by getting the virus itself by removing all COVID restrictions)
[1] Not a dig at those countries, but a statement of fact based on the mistrust the central asians have since rich countries highjacked UN vaccination programs to advance their geo-political goals. Or poor quality vaccines/equipment that spread diseases amongst Africans.
[EDIT] While I am not vaccinated, I did sign up for a vaccine trial and was rejected. So please, try not to make this personal.
