WILMINGTON — Those who received their first dose of the COVID-19 vaccine at several Delaware Division of Motor Vehicles drive-thru sites or Salesianum School in Wilmington in mid-January, will now have a couple of options for their second dose.

State officials announced plans Tuesday to focus on administering these second doses over the next few weeks. Registration and scheduling information will be listed on de.gov/getmyvaccine and will be emailed to all eligible individuals the state has email addresses for.

Gov. John Carney’s office said registration for 3,800 second-dose appointments will open later this week for those who received their first dose at the Dover DMV on Jan. 16, 17 or 18 or at Salesianum School on Jan. 18. These events from Feb. 15 to Feb. 19 will be operated by Curative Inc. at Delaware Technical Community College campuses in Georgetown, Dover and Wilmington. Registration will be done directly with Curative and individuals will be required to show proof of their first-dose vaccination date when they arrive on site.

Only the Moderna COVID-19 vaccine will be administered at the Curative second-dose sites.

The state has also requested the Federal Emergency Management Agency set up a vaccination site at Dover International Speedway for multiple days beginning as early as Feb. 20. This site would be dedicated to those who received a first dose at either the Dover DMV event or the Salesianum School clinic as well as drive-thru clinics held at the Delaware City DMV on Jan. 22, 23 and 24 or at the Georgetown DMV Jan. 23 and 24.

Dover International Speedway’s site will distribute both the Pfizer and Moderna vaccines. Scheduling has not been confirmed for these events, and is contingent on FEMA approval of the state’s request. Additional information is forthcoming, state officials said.

The site at Dover International Speedway is modeled after what other states are doing with vaccination sites at stadiums used by the National Football League, said Delaware Emergency Management Agency Director A.J. Schall.

“We don’t have an NFL stadium but we have the next best thing with the Monster Mile,” Mr. Schall said. “It’s in the center of the state, accessible off Route 1, Route 13 and is about an hour from anywhere at the most.”

Like the Curative second-dose sites, individuals will be required to show proof of their first-dose vaccination date at Dover International Speedway.

Delawareans who have lost their vaccination card should email their full name and date of birth to vaccine@delaware.gov. For those without email access, call DPH at 1-833-643-1715.

As of Monday at 11:59 p.m., the state had administered 126,615 doses of the COVID-19 vaccine. Dr. Karyl Rattay, the director of the Division of Public Health, said about 102,000 of those doses already administered have been first doses and about 25,000 are second doses.

The Centers for Disease Control and Prevention issued a report Monday night which listed Delaware as one of nine states, including the District of Columbia, who has vaccinated 10% or more of its population with at least one dose.

“We remain in the top tier of states as far as getting our population protected with this vaccine,” Dr. Rattay said.

Delaware has prioritized first doses over the last month, Gov. Carney said, but that is changing this week as large amounts of individuals are becoming due for their second doses. With the priority on second doses now, first doses will be slower to move out, Gov. Carney said.

The emphasis on first doses came when the federal government told states they could receive an increase in vaccine allotment if they could demonstrate an ability to push out doses quickly. It also was due to the fact the state wanted to move in Phase 1B of its distribution plan, which includes those 65 years old and older.

“There was a real sense of urgency in the public, number one to move out of 1A into 1B, the most vulnerable population age-wise,” Gov. Carney said. “Knowing that and doing all those first doses intensely, we knew we would be back around where we are today trying to deliver second doses with a supply that hasn’t kept up with the need for first and second doses. The need to do second doses will reduce the number of first doses that we can deliver to folks.”

State officials no longer expect to begin vaccinations of Phase 1C individuals on March 1 as originally scheduled, due to the limited supply of the vaccine and the large amount of Delawareans yet to be vaccinated in Phase 1B. Phase 1C includes those 16 to 64 years old with high-risk medical conditions and persons living in high-risk congregate settings.

The DPH’s vaccine tracker lists only 11,985 doses available in inventory, as of Monday at 11:59 p.m., but there is another shipment expected to come in from the federal government this week.

Dr. Rattay said about 107,000 individuals have signed up for the state’s waiting list for those aged 65 and older since it went live on Jan. 20. Of that total, about 32,000 have received one dose. Dr. Rattay reiterated that the number of those who have received first doses will slow this week and next with the state’s focus on second doses.

Those seniors who are not on the waiting list can register at vaccinerequest.delaware.gov.

There were numerous cases of duplicates who signed up for the waiting list, said Dr. Rattay, including one case where a single individual signed up more than 20 times.

“It doesn’t matter how many times you put your name in,” Dr. Rattay said. “It’s not like a raffle where you’ll make it more likely that you’ll get picked. So you don’t need to submit multiple times. We got you if you’re in there once. We’re going to continue to communicate to all people on that waiting list about what options are available and how things are evolving. Please stay tuned to the emails that we send out and we’re going to try, as fast as we can, to make vaccine available to everyone on that waiting list.”
