Um, most people, vaccinated or otherwise, barely notice COVID-19. That’s why they made such a stink about “asymptomatic carriers” long before they had any “vaccines”.
Try to think, at least once in a while. You have been lied to, about everything to do with “COVID”, from the start. It’s the flu.
No flu was ever remotely this infectious, esp. not cranking out the shedding that Delta does.
