New guidance from the Centers for Disease Control and Prevention this week loosens quarantine requirements for fully vaccinated people who have been exposed to COVID-19 and are asymptomatic. 

The new guidance ends the requirement for fully vaccinated people to no longer be quarantined within 90 days of receiving the second shot. 

But New York officials, including Gov. Andrew Cuomo and Health Commissioner Howard Zucker urged the New Yorkers who have had both COVID vaccine doses to not let their guard down. 

At issue is the possibility of vaccinated people still being able to contract and spread the virus to unvaccinated people. 

"From the outset of the pandemic, New York State has followed the science and listened to the experts, and quarantine requirements only for New Yorkers who have received both shots will be similarly updated to reflect the CDC's new guidance," Cuomo and Zucker said in a joint statement. "However, the science regarding COVID transmissibility post-vaccination remains unsettled, and this updated guidance is not an all-clear for New Yorkers to let their guard down."

About 10% of New York residents have received at least one of two doses of the COVID-19 vaccinated. Eligibility is greatly expanding next Monday, when people with a range of comorbidities are scheduled to qualify.

People who have received the vaccine are still expected to wear masks and socially distance.

"All New Yorkers, including those who have been fully vaccinated, should continue to wear masks, social distance, and be smart until herd immunity is reached and this pandemic is fully relegated to the history books," Cuomo and Zucker said.
