Broadway theaters announced an update to vaccine protocols for children Wednesday, in line with the new citywide mandate. 

Starting Dec. 14, children aged 5 to 11 must show proof of receiving at least one dose of the COVID-19 vaccine to attend a Broadway show, and must be accompanied by a vaccinated adult. If the child has been vaccinated less than 14 days before the performance, he or she must also provide proof of a negative COVID-19 test for entry. 

Broadway theaters had previously offered the option for children in that age range to just show proof of a negative COVID-19 test for admittance, without the need to be vaccinated. 

The policy update follows new rules announced Monday by Mayor Bill de Blasio, in which children in that age range must present proof of one dose of the vaccine for entry to theaters, indoor dining, gyms and other indoor entertainment venues. 

“With safety and security top of mind, we continue to stress the unrelenting desire that we have to keep our theatregoers, cast and crew safe,” said Broadway League President Charlotte St. Martin.
