It's probably an issue of not being in a position to do much about them. He seems pretty proud that he got a vaccines out so fast during his first term. I personally think that he knows one of the vaccines are good because he had a hand in it. I mean think about it. If your job is to protect your country and you know that multinational industrialists are going to kill your people with viruses and fake vaccines you would try to make a vaccine that actually works properly as fast as you can. Trump also might not want to tip his hand. He probably had the right vaccines delivered to the right people or gave them placebos. If the enemy knew for sure that one vaccine was actually a good vaccine then they would attempt to get rid of it because it would put a kink in their plan. I mean it's a weird comparison but have you seen the Black Widow movie? In the movie there is a "cure" for the brainwashing and mind control all of the woman in the Red Room were subjected too. The bad guy's real targets were not the women that escaped the mind control but the ones that were carrying large amounts of the "cure" because it's a force multiplier. I would imagine it would be a similar playbook if Gates and Globalists knew there was a good vaccine. They would go after the good vaccines first and THEN the people carrying them.
