Federally-supported COVID-19 vaccination sites in Florida have resumed administering the single-dose Johnson & Johnson vaccine on Sunday.

The sites opened to the public at 7 a.m. However, due to inclement weather, it closed at 9:45 a.m. temporarily. It was cleared and reopened by 11 a.m.

They once again offer the Johnson & Johnson vaccine after a ruling from the Centers for Disease Control and Prevention (CDC) to resume use on Friday. The public health agency said that the benefits outweigh the risks, despite more than a dozen women developing rare blood clots after receiving the vaccine.

Officials said that each Florida site -- Orlando, Tampa, Jacksonville and Miami -- will have the capacity to administer up to 3,000 doses per day. That includes the site at Valencia College's West Campus. No appointments are needed for the Orlando location.

People were lined up at the vaccination site on Sunday to receive the vaccine.

Organizers at each site said that staff has received additional training based on guidance from the CDC and the FDA. In addition, the COVID-19 consent and screening form every person must sign has been updated.

In Section 3 of the form, titled "Immunization Screening Guidance for COVID-19 Vaccine," it asks:

"Do you have a bleeding disorder or are you on a blood thinner/blood-thinning medication?" It also asks, "Are you a female age 18 to 49 years old receiving the Janssen (Johnson and Johnson) COVID-19 vaccine?"

Out of the nearly eight million people vaccinated before the U.S. suspended Johnson & Johnson's shot, health officials uncovered 15 cases of a highly unusual kind of blood clot. Three of them fatal. All were women and most were younger than 50.
