I am not sure why you believe Trump supporters are anti-vaccine.
I would say we are skeptical that a truly effective vaccine is in the works. It appears that most doctors believe any vaccine will be no more than 40-50% effective. Trump keeps saying there will be one soon. Doctors say maybe next spring and only as good as previously mentioned. Therapies look to be what we will depend on for the foreseeable future. And with the likes of leronlimab, I am good with that.
