SCHERERVILLE â Donna Spivak has been a teacher for 37 years, and in a school year guided by the coronavirus pandemic, the longtime educator said she feels invisible. Spivak, who is 58, told The Times she recently secured an appointment to receive a COVID-19 vaccine, which she received after speaking to someone at the health department after explaining she is a teacher, and her husband is an elderly cancer survivor. "I waited, I think it was almost a month, and then when I finally got there, they just said, 'No, we're not doing teachers.' So they just turned me away," said Spivak, a fifth grade teacher at Grimmer Middle School in Schererville.
