Going to see a teacher tonight. she had her first vaccine for covid about 6 days ago, and she is taking a rapid test right now before. i see her, if she is negative is it safe?

Maybe: Vaccines for anything take weeks to generate the antibodies needed to avoid any germ. Rapid tests have some false positives and some false negatives, which depend on the type of test & how well it followed protocol. Such rapid tests are the common screening tool used when you visit secure areas & when necessary & they do provide a level of comfort. That said, she may be safe/or not.

Distance, Mask: Probably safe. 6 days after 1st dose of vaccine antibodies are “getting up there” but not yet at peak (14-21 days). Negative “rapid test” doesn’t prove teacher is negative but at least is at low risk of spreading virus. All things considered, you are at risk but at low risk. Wear a mask. Stay (at least) 6’ apart
