IMPORTANT INFORMATION: The Pfizer pediatric (5-11 years) vaccine is a 2-dose series, spaced 21 days apart. This timing is vital to the overall effectiveness of the vaccine. This means we will be scheduling (2) appointments for your child. Failure to arrive for your first or second appointment will disqualify you from our limited inventory. Due to storage requirements, Einstein will only be able to offer specific dates/time slots for COVID-19 vaccines.
