I think some effectiveness has been demonstrated. Hospitalizations and deaths are lower amongst the vaccinated.
But, I also think the vaccine hasn’t done what they’d hoped it would, and like they’re acting like it does, that is prevent transmission and infection.
There’s no data, that I know of, that says if one is vaccinated their ability to transmit is lower. I think its all hope and conjecture, and hope is not a strategy.
The reason you haven’t seen any data is because Big Pharma lobbied and won. Congress passed a bill stating that Big Pharma doesn’t have to disclose any data on their vaccines until the year 2079.
Says who? Oh...yeah...the people who make money pushing the vax.
