You have to understand this: Trump can never say publicly how bad vaccines are. He would right away be accused by all the big media, and the majority of the corrupt government (left and right!) of murdering the American population. So he has to be smart.
He gave the world ‘vaccines’, therefor the lockdowns can be ended, and the plan to destroy humanity through endless lockdowns fails.
Of course he needs to say they are ‘safe and effective’, but even this is waking up the world, as people hear the claim ‘safe and effective’ while around them they see the destruction these vaccines are causing. This is undermining their blind faith in the governments and ‘health’ institutions, which is again a massive blow on the stronghold of the elites’ control over the world.
