That's easily disproven by a basic bloodwork panel.
I've had two doses of the Pfizer vaccine and subsequent bloodwork, and my white blood cell count is just fine and ducky.
Seriously..the stuff that floats around in the rumor mill on the vax is just outright comical at times. Unfortunately, it's also just plain dangerous as it can dissuade people from getting a vaccine that might just prevent them from dying from COVID if they're unfortunate enough to come down with it.

Consider yourself lucky to be in the placebo group.
