I’m not aware of any support for the proposition that vaccinated people are infecting others with COVID. The evidence appears to be to the contrary. I do acknowledge that physicians and the CDC are being cautious until more studies are done. Also, a direct recent exposure to the virus could trigger stricter protocols.
It’s true that just about anything is within the realm of possibility. I’m talking about facts and evidence sufficient to shape public health policies.
Edit:
@Djsfantasi: The CDC guidelines expressly state that: "If you've been fully vaccinated [and] you've been around someone who has COVID-19, you do not need to stay away from others or get tested unless you have symptoms." There's an exception for those who live in a group setting like a "correctional or detention facility or group home." Then you should stay away from others for 14 days and get additional testing even if you don't have symptoms. Maybe your doctor's advice was given before the CDC guidelines were changed? I hope you’re not quarantining and canceling plans due to misinformation.
