...if any or all of the vaccines turn out to be unhealthy, it won't be a good luck even promoting it

Getting a chance to live is not unhealthy, and it's not about having luck.

Though the vaccines may not be 100% effective, and certain people may end up with complications, it's still a lot better solution than doing nothing at all.

I mistyped. I meant to say if the vaccine turns out to be unhealthy, it would not be a good look. You do know the conditional in English, right?
