Oh so you don't know the unvaccinated are spreading the virus at a higher rate than the vaccinated. Thanks for admitting that.
Since I have a brain that can do very simple math, I know it for a fact. Every scientist and dr agrees. I’ll try and show you some things :
1) lower viral Loads:
One massive analysis of Delta transmission comes from the UK REACT-1 programme, led by a team at Imperial College London, which tests more than 100,000 UK volunteers every few weeks. The team ran Ct analyses for samples received in May, June and July, when Delta was rapidly replacing other variants to become the dominant driver of COVID-19 in the country. The results suggested that among people testing positive, those who had been vaccinated had a lower viral load on average than did unvaccinated people. Paul Elliott, an epidemiologist at Imperial, says that these results differ from other Ct studies because this study sampled the population at random and included people who tested positive without showing symptoms.
2) 8 times less likely to get symptomatic Covid
3) At least 90% of the cases are among the unvaccinated.
4) Vaccinated contagious for less days:
“A vaccinated person may have the same viral loads as an unvaccinated person, but that high level of virus lasts only three to four days compared with an unvaccinated person who could be contagious for up to 10 days, said Suresh Mittal, professor of virology at Purdue University’s College of Veterinary Medicine.“
5) The surge by delta so far is much worse in the very low vaccinated areas compared to the very highly vaccinated areas.
I hope this helps.
