Hi Mina, the answer is straightforward.
Your statement that "the vaccinated are still just as likely to infect others" is scientifically wrong. Vaccinated persons infect others less (<) than unvaccinated persons. 1/5

CDC: ⬆️evidence that fully vaccinated are < likely than unvaccinated to acquire or transmit to others. However, the risk for breakthrough infection in fully vaccinated cannot be completely eliminated when there is continued community transmission. cdc.gov/coronavirus/20… 2/5

In short, vaccination reduces transmission although it doesn't bring it down to zero. The Delta variant has reduced the benefit of vaccine (lowering transmission), but has not eliminated it. The cited NYT and CDC sources confirm this, even with the Delta variant. 3/5

COVID vaccines remain effective in⬇️ transmission, symptomatic & severe illness & death. However, the Delta variant has⬇️this effectiveness. We MUST TAKE ACTION to stop the GLOBAL spread of the virus to avoid facing new and more > dangerous variants with even⬇️effectiveness 4/5

Mass vaccination globally is urgently needed to END the pandemic. Canada MUST ACT NOW to achieve this. @JustinTrudeau @erinotoole @theJagmeetSingh @AnnamiePaul where do you stand?
