People who receive two COVID-19 jabs and later contract the Delta variant are less likely to infect their close contacts than are unvaccinated people with Delta. Relevant Nature article (October 5, 2021).
However, good job on the masks part, please keep wearing them! :-)
"The study shows that people who become infected with the Delta variant are less likely to pass the virus to their close contacts if they have already had a COVID-19 vaccine than if they haven’t1. But that protective effect is relatively small, and dwindles alarmingly at three months after the receipt of the second shot. "
> less likely to infect their close contacts than are unvaccinated people with Delta
I don't see these as contradictory. Vaccines are more effective against transmissions, yet vaccines don't slow down transmissions in a significative way. As per the article:
> Unfortunately, the vaccine’s beneficial effect on Delta transmission waned to almost negligible levels over time. In people infected 2 weeks after receiving the vaccine developed by the University of Oxford and AstraZeneca, both in the UK, the chance that an unvaccinated close contact would test positive was 57%, but 3 months later, that chance rose to 67%. The latter figure is on par with the likelihood that an unvaccinated person will spread the virus.
> A reduction was also observed in people vaccinated with the jab made by US company Pfizer and German firm BioNTech. The risk of spreading the Delta infection soon after vaccination with that jab was 42%, but increased to 58% with time.
Fully agree on the mask though. Plus social distancing, if possible.
