Yeah I am not so sure about this particular video. It talks about "The vaccines" and goes into great details of how much percentage of immune system is reduced in the first, second and booster shots without even mentioning which particular vaccine.

Also, it claims that each dose of the vaccine has different ingredients and 18 different strains of bacteria in first booster, and 8 strains in second ... all this sounds fake precise. There are plenty of doctors who talk about what the vaccine does without this kind of fakery.
