It could be that Trump is just setting himself up to oppose mandatory vaccine. If he first establishes he is super pro-vax, it might give him more credibility to oppose making it mandatory. This could actually be moving chess pieces into place before a bigger battle. Mandatory vaccination might be the shot heard round the world. I think that could have the potential to get an actual civil war going. I could easily imagine Fox and CNN screaming at each other about this as live action coverage of warfare in the street runs behind them. “If you just accept the mandatory injection of this toxic sludge and this tracking microchip pass, none of this guerilla warfare would be necessary.”
