Pfizer Confirms Covid-Vaccinated People Can “Shed” Spike Protein and Can Harm the Unvaccinated. https://www.algora.com/Algora_blog/2021/10/04/pfizer-confirms-covid-vaccinated-people-can-shed-spike-protein-and-can-harm-the-unvaccinated

I don't know how long they shed. Some think it's worst in the first 30 days after the Covid shot. One doctor had a receptionist that was pregnant. No patients were allowed in his office if they had a Covid shot within the last 30 days, to protect the receptionist's pregnancy.
