IMO there was no way Trump could completely avoid the vaccine issue once the virus was released. Thru Q we all knew there would be casualties. By telling the people to take the vax he prevented the DS media from jumping right on him if he said the opposite. He knew that the anons have done the research and would not be taking the vax. I believe he also thought it would stop others from getting the jab just because it was him saying it. Under the circumstances I don't see how he could have done it differently.
