At a pivotal moment in the pandemic, Nature explores key questions about the vaccines that countries are racing to deliver while viral variants spread around the globe.

"And a study
17 by Public Health England has found that even a single dose of either the Pfizer–BioNTech or Oxford–AstraZeneca vaccine reduced the spread of disease from infected individuals to household members by up to 50%. “It’s likely that all the vaccines have some similar effect,” says Michael Weekes, a viral immunologist at the University of Cambridge, UK. “Overall, it’s quite an optimistic picture.”"
Studies show that vaccines reduce the spread of SARS-CoV-2 by more than 80%, but the Delta variant is creating fresh uncertainty.

"Both studies found that two doses of the Pfizer–BioNTech vaccine were 81% effective at preventing infections. Those who did get infected were also less likely to pass the infection to household members than were unvaccinated individuals.
The first study saw a drop of 78%, and the second 41%, in infectiousness — with the large difference in numbers perhaps explained by the fact that the estimates are based on a very small number of vaccinated people who were infected and then infected others."
Background Pre-Delta, vaccination reduced transmission of SARS-CoV-2 from individuals infected despite vaccination, potentially via reducing viral loads. While vaccination still lowers the risk of infection, similar viral loads in vaccinated and unvaccinated individuals infected with Delta...

"Conclusions Vaccination reduces transmission of Delta, but by less than the Alpha variant."
A man getting vaccinated in LA People who are fully vaccinated against covid-19 are far less likely to infect others, despite the arrival of the delta variant, several studies show. The findings refute the idea, which has become common in some circles, that vaccines no longer do much to prevent...

“They absolutely do reduce transmission,” says
Christopher Byron Brooke at the University of Illinois at Urbana-Champaign. “Vaccinated people do transmit the virus in some cases, but the data are super crystal-clear that the risk of transmission for a vaccinated individual is much, much lower than for an unvaccinated individual.”
"The vaccines are incredibly effective at preventing the most serious complications of COVID-19, which is hospitalizations and deaths."

"Dr. Alsip told KENS 5, "There's also data to suggest that those who are vaccinated carry fewer viral particles in the respiratory tract, which makes them less likely to actually spread the disease to somebody else, even if they don't have symptoms.""

"As expected, because no vaccines is 100% effective, infections in fully vaccinated persons (e.g. breakthrough
infections) have been observed,
albeit at much lower rates than infections among unvaccinated persons; vaccine effectiveness against severe disease remains high."

Repeating the same ignorant claim over and over again does not make it true. VACCINATION. DOES. SLOW. THE. SPREAD. The experts and current data is very clear on this. It's also blindingly obvious to anyone with even a basic understanding of biology. You people are spreading misinformation that is getting people killed. Stop it.
