The Pfizer phase 3 study’s last endpoint is 7 days after the second shot. Does anyone know why the CDC recommends waiting 2 weeks for full protection? Are they just being the CDC again?
People don’t really distinguish between “I am protected” and “I am safe for others to be around”. If someone got infected prior to their vaccination and had a relatively-long incubation period, they could infect others; I don’t think it’s a coincidence that two weeks is also the recommended self-isolation period for people who may have been exposed.
