I didn't watch it until afterwards, but that video is designed to influence rather than be neutral (just look at the selected edits and attempts to drive fear). Like I posted, the general consensus in the scientific community is that vaccines and antibodies are varyingly effective, just like the study I posted.
Did you look for any evidence to refute or clarify the statements in that video? A quick search found this:
"
Project Veritas’ Nick Karl and Pfizer “exposed” video was one in a long series of deceptively edited, bad-faith efforts from the organization and its social media cheerleaders. Any efforts from Project Veritas were highly likely to be misleading. Moreover, global scientific consensus had already recognized that COVID-19 infections confer some degree of immunity — and they still overwhelmingly favored vaccination."

I'm not saying the rebuttal is correct and the video you posted is totally wrong, Not at all. Just that it is always a good idea to try to refute your own argument first to ensure you aren't being manipulated.
