A leaked slideshow from the CDC that suggested the Delta Variant was just as transmissible among vaccinated individuals as unvaccinated individuals caused a lot of skepticism.
Many people were already skeptical of the vaccine to begin with, but this gave them something to back up their claims.
The study has come up in discussion with the Minnesota Senate when discussing vaccine mandates as well.
The study about COVID transmission and the Delta Variant
The truth about the study is that it did find levels similar between the vaccinated and unvaccinated people with the Delta Variant.
Limits in the study may have missed differences between the two groups, and the study did not look at the rest of the vaccinated population that was less likely to become infected to begin with.
Another limitation is that the amount taken could have an impact on the viral load: someone with a runny nose might give more material in the sample than someone with a plugged nose; the person with the plugged nose may be sicker though.
Another study found the same level of virus among vaccinated people who had Pfizer or AstraZeneva and unvaccinated people, but the vaccinated were less likely to transmit it.
There will always be transmission, but it appears that the more vaccinated an area is, the less of a transmission rate there will be.
