> 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.
