The city health department says it has closed a child care program in Brooklyn after it failed to provide access to student vaccination records amid the ongoing measles emergency.

It's the first closure since health officials ordered residents of one Brooklyn neighborhood to be vaccinated for measles.

The health department on Monday said the Williamsburg preschool, United Talmudical Academy, repeatedly failed to provide access to medical and attendance records. It says the school will not be allowed to reopen until it submits a "corrective action plan" approved by the department.

Health officials said inspectors visited the school five separate times, but were unable to obtain vaccination or attendance records.

NY1 was told two measles cases were connected to United Talmudical Academy, although it's unclear if the virus was contracted at the school or on the premises.

Health officials say 329 cases of measles have been confirmed since the beginning of the outbreak last October. Most of the cases are children under 18 and have been reported from Williamsburg and Borough Park, Brooklyn.

There have been no deaths associated with the outbreak.

In an effort to contain its spread as the Passover holiday approaches, the mayor's office has required every person older than six months in the zip codes 11205, 11206, 11211, and 11249 — all in Williamsburg — to receive the measles vaccine. The order applies to anyone living, working, or going to school in the area.

The city's Department of Health and Mental Hygiene has been reviewing vaccination records of every person who may have been in contact with measles patients, and de Blasio says anyone who is not vaccinated could be fined $1,000. The city said Tuesday that it would help everyone covered by the order get the vaccine if they can't get it quickly through their regular medical provider.

The city has already ordered religious schools and day care programs serving Williamsburg to exclude unvaccinated students or risk being closed down. 23 yeshivas and day care programs have received notices for failing to follow the order, the health department said Monday.

The outbreak started in Williamsburg after a child who traveled to Israel contracted the virus in October last year. Nearly 300 people — mostly under the age of 18 — have become infected with measles, which, if left untreated, can have serious consequences — even death.

Officials acknowledged they have been battling an epidemic of public misinformation and a growing anti-vaxing movement, which falsely claims vaccines can harm children.

Medical experts almost unilaterally concur that the vaccines are safe and do not cause autism. The city notes that nine CDC-funded or conducted studies since 2003 have found no link between the vaccines and autism spectrum disorder.

New Yorkers who want to know where to get the vaccines should call 311 or access the Department of Health website.
