[WATCH] CDC Updates Mask Mandates, Releases New COVID Info
A new study shows the Delta Covid-19 variant produced similar amounts of virus in vaccinated and unvaccinated people if they get infected — illustrating a key motivation behind the federal guidance that now recommends most fully vaccinated Americans wear masks indoors.
Experts say that vaccination makes it less likely that you’ll catch Covid-19 in the first place — but for those who do, this data suggests they could have a similar tendency to spread it as unvaccinated folks. “High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus,” Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention, said in a statement Friday.

I'm sick and tired of Republicans making shit up about the CDC and their motives. You don't want to wear a mask? Fine. But don't claim that the CDC has some secret political agenda.
I'm heading to the Senate floor right now to call them out for their scare tactics and lies.

On Thursday, a CDC internal document said the Delta variant was roughly as transmissible as as chickenpox, whereas an early strain was closer to the common cold. This means that, under certain conditions, an infected person may have transmitted to two or three people, on average, early in the outbreak. But now, with Delta, that number could be five to nine.
⚠️’CANARY IN COALMINE’ mega outbreak. Many large public events in Massachusetts town in early July led to 469 #COVID19 cases➡️ 74% in **fully vaccinated**; 90% sampled #DeltaVariant. *Viral loads similar* in fully vaccinated vs unvaccinated. CDC worried.🧵https://t.co/lmZHaBU8SB pic.twitter.com/aokTxowopW
