You have to remember what was going on: The Great Reset. They're going to try and salvage it this fall but they originally planned to do it under Hillary. Operation Warp Speed wasn't about saving lives from Covid. It was about stopping the Great Reset. The entire Reset was/ is predicated on crippling shut downs.

Shut down a nation long enough and there is no economy to go back to. Effectively forcing people to accept the Great Reset. They always planned on using the mRNA vaccines to genetically modify the population but didn't want to release it as early as Trump did so they could permanently kill the economy first. This was a vital step for the Great Reset and Trump effectively ruined their original plan. Essentially saving the world from a dark age.

He had no choice but to support and continue to support the vaccine. It's also why he doesn't talk about how dangerous the vaccines are. So he can use plausible deniability when all this finally ends in military tribunals. With Trumps vaccines, they couldn't justify staying shut down anymore.

In chess we call this a combination. A strategy that assures victory but usually requires a sacrifice. The only way to win this game was to play the vax card super early. Millions will die from the vax but it's better than the entire human species being enslaved with the Great Reset.
