Vaccines being administered at pop-up NY airport sites through Friday

Pop-up vaccinations take flight at some of New York's airports beginning Monday.
JFK International, LaGuardia and Westchester County Airport are among the places that will begin administering vaccines Monday through Friday.
The sites will be administering the single-dose Johnson & Johnson vaccine. But supply is limited on a walk-in, first-come, first-served basis.
The new program comes on the heels of pop-up sites at several train stations in the Hudson Valley, New York City and Long Island.
