I think the vaccine endorsed by the right is called Ivermectin.
Oh, you mean for Covid? We use BioNTech and Moderna for that.
Please stop confusing people on the right with vulnerable uneducated people in general. There are plenty of those on the left and right. Donald Trump does not represent the right. He represents Trumpers. Unfortunately many of those who shape the Republican party are Trumpers. But there are obviously perfectly reasonable people on the right who are not Trumpers.
The ignorant are exploited by both sides. Please be careful to distinguish between the exploiters and the exploited.
His push for vaccine development and encouraging people to get it might be commendable, but they ring hollow and lack effectiveness because of his past stances.
