Pending FDA Emergency Use Authorizations (EUAs) for the new Pediatric Bivalent COVID-19 Vaccine in the next few weeks, the Centers for Disease Control and Prevention (CDC) is planning for a pre-ordering period during which certain vaccine doses will be made available to each jurisdiction based on pro-rata allocation. During this pre-ordering phase, the PA Department of Health (PA DOH) and the Philadelphia Department of Public Health will submit vaccine preorder requests on behalf of providers. For Philadelphia County the deadline to order was Sept. 27. For all other counties in the Commonwealth, the deadline to submit preorder requests is Sept. 30 at 4:00 pm. Click here to submit a vaccine request form to preorder the vaccine through the PA DOH. Please do not order pediatric Pfizer Bivalent vaccines in PA SIIS until advised to do so, as any order put on PA SIIS for this product will be deleted. Vaccine preorder requests are not guaranteed to be fulfilled, as the supply may initially be limited. Doses that are pre-ordered will be processed for delivery following the issuance of the EUA. Additionally, the deadline for HRSA Health Center COVID-19 Vaccine Program participants to pre-order Pfizer bivalent boosters for pediatric patients ages 5-11 was Sept. 28 and was capped at 100 doses per site. The updated CDC Fall Vaccination Operational Planning Guide includes more detailed information about pediatric bivalent boosters.
