The same way that my friend who is vaccinated was infected by his unvaccinated wife. Close quarters with an infected person is going to increase risk for some one who is vaccinated. The Pfizer vaccine is 38% effective [1] at preventing infection on average. It’s obvious that spending 8 hours next to someone who is actively infectious will reduce that efficacy rate.

[1] for the Delta variant, which at this point is what matters

38% is for the delta variant and a single shot. For the recommended 2 shots, protection from the delta is 88% compared to 93% for the alpha.

What about the vaccinated spreading the disease?
