Getting appointments for 16- and 17- year-olds When 16- and 17-year-olds are registered for a vaccine, a provider will let them schedule if the Pfizer vaccine is available there. Providers will see the age on the registration and know if they can be scheduled. Health departments are working with providers to store and distribute the Pfizer vaccine to locations that might not have that brand. The Barry-Eaton District Health Department is holding a Pfizer clinic on Monday, April 19 at the Lansing Mall. People can schedule an appointment online or call 517-541-2605 if they need special assistance or do not have internet access.
