Mayor Eric Adams announced on Monday the end of the COVID-19 vaccine requirement for school proms.

The city is still encouraging students to get vaccinated and wear high-quality masks at proms and graduations. The city did not have a vaccine requirement for students for graduations, though guests will still be required to be vaccinated to attend graduations in school buildings, according to a statement from the city.

As of Monday, 90% of 13 to 17 year olds in the city were vaccinated with at least one dose, according to city Department of Health data. Only 24% of the same cohort received a booster.

"Vaccinations got us to where we are today, so I want to thank the millions of New Yorkers who went out and got vaccinated, doing their part to keep our city safe," Adams said in a statement announcing the move. "I encourage anyone who hasn't yet gotten vaccinated to do so, and to all of our students, congratulations!"

Students attending ceremonies at private venues will still be required to follow the vaccination requirements of the facility, the city said.

"Vaccinations remain a lifesaving tool. Masks worn indoors continue to reduce risk of transmission," city health department commissioner Dr. Ashwin Vasan said in the statement. "But another critical resource for health is togetherness and celebration - for which these events are so critical in the lives of young people."

"Graduation and prom are such momentous occasions in the lives of our young people, which is why I am so excited that thanks to the hard work of our school communities, we have come to a point where we can safely take this next step," Chancellor David Banks added.

The move comes as city, state and federal legislators called on the mayor to lift the vaccine mandate for proms in recent months. On April 4, Rep. Nicole Malliotakis penned a letter to Banks asking him to end the requirement. Councilmen Joe Borelli and David Carr, both Republicans, joined three Republican state legislators in co-signing the letter.

On Sunday, Borelli and Councilman Robert Holden, a Democrat, signed onto another letter imploring Vasan to reconsider, the two wrote on Twitter. Borelli thanked Adams Monday for the reversal.
