School employees get single-shot COVID-19 vaccine March 13, 2021 at 11:25 PM EST - Updated March 13 at 11:25 PM More COVID-19 vaccines were made available to teachers Saturday as some Treasure Coast and Palm Beach County schools and gyms became vaccination clinics. "So to get the vaccine today, it's wonderful. We're so grateful," Martin County teacher Katherine Snore said. Snore was among those getting the single-shot Johnson & Johnson vaccine. School district officials said about 900 vaccines were to be administered at Martin County High School, where 30 people at a time were allowed into the gym. Snore said this is part of the process of getting back to some sort of normalcy.
