I do disagree with you tactically, though. The percentage of the adults in my country (the US) who have received one dose is closer to 2/3. That leaves about 1/3 of eligible people unvaccinated. This is roughly the same 1/3 of people who don't believe in evolution, and the same 1/3 that believe that Covid is a hoax, or that you can beat it by taking horse dewormer.
Trying to fight this by winning over hearts and minds is like when serious scientists try to debate evolution with creationists. It's a waste of everyone's time. The only way to get the vaccine numbers up is to make vaccines mandatory for school, employment, travel, etc like other vaccines are.
