 The U.S. Centers for Disease Control and Prevention (CDC) said on
Wednesday the vaccines have been shown to prevent symptomatic
COVID-19, thought to play a greater role in the transmission of the
virus than asymptomatic disease.
"Individual and societal benefits of avoiding unnecessary quarantine
may outweigh the potential but unknown risk of transmission (among
vaccinated individuals)," the CDC said.
The agency has laid down strict criteria for people who would no
longer have to quarantine after the vaccinations, including having
received both doses of a two-dose vaccine.
People who choose not to quarantine should do so only if they
received their last dose within three months, and should only avoid
14 days quarantine after their last shot, the time it takes to
develop immunity, CDC said.

Fully vaccinated persons who do not quarantine should still watch
for symptoms for 14 days following an exposure.
Two-dose vaccines from Pfizer Inc and Moderna Inc have been
authorized for emergency use in the United States. Johnson & Johnson
applied for a U.S. authorization of its single-dose shot last week.
