If people can get Covid after being vaccinated, they can spread the virus as well.
You're being disingenuous. 5,000 out of how many millions? What tiny fraction of a percent?
Certainly some small minority of people who have received the vaccine can transmit the virus. Obviously, most of which will be during the short window between receiving the vaccine and it taking full effect. And obviously, almost all amongst people who have had only one dose of a two dose programme. Because this is not a secret, it's known and publicised by governments and the vaccine companies.
And even then, with a full two doses and a window for them to take effect, vaccines are not 100% effective for everybody... but they are a hell of a lot closer to 100% than doing nothing, which is 0% protective.
... The last year has shown us just how quickly the virus spreads amongst people who haven't been vaccinated.
What? You forgot about the 400,000 that the CDC and Harvard show were killed by the vaccine so far in the USA.
Do you really need me to show you the stats for the shedding? You believe me because you are too stupid to know how to do the research?
