The CDC now says that people who’ve received either authorized COVID-19 vaccine do not need to quarantine after exposure to a person with COVID-19, provided they meet all of the following criteria:
- They’ve received both vaccine doses, and at least 2 weeks have passed since the second dose
- They are within 3 months of their last dose
- They’ve not developed COVID-19 symptoms since their exposure
Anyone not meeting all of the above should abide by current CDC guidance on quarantining (see link below).

In other vaccine updates, the CDC has added information about delayed injection-site reactions to its website. In particular, the agency notes that some people, including some Moderna trial participants, have experienced injection-site reactions starting a few days through the first week after the first dose. These reactions are “sometimes quite large,” the CDC says. However, they are not a precaution or contraindication to receiving the second dose. People with such reactions should receive their second dose of the same vaccine on schedule — in the opposite arm, if possible. It’s unknown whether the reaction will recur with the second dose.
