(CNN)A mistake on Walmart's website allowed adults under the age of 65 with comorbidities to register for vaccination appointments in Florida.
The error contravened Gov. Ron DeSantis' "Seniors First" vaccination plan, but Walmart says it will honor appointments made during the window when the expanded access was available.
Earlier this week, Florida said that vaccines would be available in 119 Walmart and Sam's Club locations throughout the state. And on Walmart's scheduling website, Florida residents deemed to be extremely vulnerable to Covid-19 by hospital providers were able to register.
Under CDC guidelines, comorbidities include cancer, chronic kidney disease, obesity, and heart conditions.
However, DeSantis last month said the state would be prioritizing those who are 65 and above along with long-term care facility residents and staff and health care personnel with direct patient contact for the vaccine.
He said that only hospital providers could vaccinate people they believe are extremely vulnerable to Covid-19.
A Walmart spokesperson told CNN its scheduling program defaulted to the criteria on the DOH website.
But despite the mix-up, Walmart says it will honor the appointments.
"Walmart is working to align our scheduling system with the specific populations the state has asked us to vaccinate under the federal retail pharmacy partnership. We are honoring all appointments that have been made to date in all categories listed in the Executive Order," the Walmart spokesman added.
The spokesperson said the retailer didn't know how many people registered for the vaccine but promised to honor all who did.
CNN has also reached out to DeSantis' office for comment.
The Biden administration announced last week that the federal government would begin direct shipments of coronavirus vaccines to retail pharmacies, with a total of one million doses going to about 6,500 stores as part of the program. These doses are separate from the allocations that the federal government sends to each state, though they are still subject to each state's eligibility guidelines.
The National Association of Drug Stores says the goal to administer 100 million doses of Covid-19 vaccine in 30 days is realistic, but pharmacies will need enough doses to do so.
"Ultimately NACDS member pharmacies can meet and exceed the 100 million vaccinations in a month threshold, yet it's important to understand that the supply of vaccines remains the rate-limiting factor in the vaccination effort," said Steven Anderson, NACDS president and CEO.
