Mississippi children aged 5-11 are now eligible for the COVID-19 vaccine, expanding full access to vaccination to the widest range of Mississippians in the pandemic. As of Monday, state health departments across the Magnolia State are delivering free shots of the Pfizer mRNA vaccine to school-aged children. Parents looking to vaccinate their children against COVID-19 should sign up at the Mississippi State Department of Health’s scheduling website or speak to their primary care providers to schedule a dose elsewhere.
