COVID vaccinations open up to all, people rush to book shots LEAH WILLINGHAM, Associated Press/Report for America March 16, 2021 FacebookTwitterEmail JACKSON, Miss. (AP) — Appointments to get the coronavirus vaccine in Mississippi opened up for everyone over the age of 16 on Tuesday, and thousands of residents rushed to book their shots. Robin McCall made appointments for her 17-year-old twin daughters. She has a 15-year-old son who has been treated for leukemia. “He has a compromised immune system so these vaccines for our family are very important for him,” said McCall, who got vaccinated weeks ago because she has a heart condition that made her eligible.
