*Pfizer Availability:  Due to storage and handling constraints, we are only able to offer limited quantities of Pfizer each day on each mobile unit. If you have a preference to receive the Pfizer vaccine instead of the Johnson and Johnson vaccine, or are between the ages of 12-17, we highly recommend reserving an appointment slot in advance of your visit. Walk up Pfizer doses will be available on a case by case basis. Please keep in mind all approved COVID-19 vaccines are equally effective at preventing serious illness.
