Lehigh Valley Health Network will hold its largest COVID-19 mass vaccination session to date at Dorney Park & Wildwater Kingdom in Allentown on Thursday.

The clinic can handle 3,600 people in the state of Pennsylvania’s Phase 1A by appointment only.

Those without an appointment will not be eligible for vaccination.

The drive-through clinic will be held from 8 a.m. to 4 p.m. First doses of the Pfizer vaccine will be administered for free.

To schedule an appointment for the Dorney Park drive-through clinic or any other LVHN COVID-19 vaccination event, people in Phase 1A can sign in to MyLVHN. You also can schedule an appointment by calling our COVID-19 Hotline at 833-584-6283 (833-LVHN-CVD). Appointments will be filled on a first-come, first-served basis.

LVHN is committed to keep our community informed about vaccine availability in real time.

When LVHN receives a vaccine shipment, people with a MyLVHN account will see an announcement in the portal that appointments are available. We also will post a green alert at the top of our website, LVHN.org, telling you that appointments are available. LVHN typically receives vaccine shipments on Tuesdays when supply is available. People seeking a vaccination should check MyLVHN regularly for the latest announcement. To confirm your eligibility for a vaccination for any LVHN COVID vaccination event, the public can sign up with MyLVHN, the health network’s free, secure and easy-to-use patient portal.

More than 300,000 people in Phase 1A are waiting to get vaccinated by LVHN. Appointments are filled on a first-come, first-served basis and are taken very fast.

LVHN administers the vaccine fast, using all the doses we receive within one week.

When all available appointments are filled, people with a MyLVHN account will see an announcement in the portal that appointments are no longer available.

LVHN has extensive mass immunization experience, hosting drive-through flu shot clinics for nearly two decades, where we have vaccinated as many as 8,000 people in one day. We will apply that experience to large-scale drive-through COVID-19 vaccine events throughout the region to supplement our existing vaccination locations as supply is made available from the state.

LVHN will continue to expand its mass immunization program. Sites in other locations are being established in coordination with local health bureaus and authorities. An appointment is needed to receive the vaccine at all LVHN locations, including the mass-immunization sites.

Even after receiving the COVID-19 vaccine, people must continue to wear a mask in public, wash hands frequently and stay socially distant until the majority of our community is vaccinated. For more details about vaccines, visit LVHN.org/vaccines.
