Florida health officials say two women dressed up as elderly people in an effort to get a coronavirus jab.
The women, who appeared to be in their 20's, faked their identity to get a second vaccine, Orange County health administrator Dr Raul Pino said.
"Yesterday, we realised a couple of young ladies dressed up as grannies to get vaccinated for the second time," Dr Pino said in a news conference on Wednesday (US time).
"So I don't know how they escaped the first time but they came back to get vaccinated.
"[They were wearing] bonnets, gloves, glasses - the whole thing."
The women were issued trespass warnings after their birth dates did not match the dates registered for the vaccine, a spokesperson for the sheriff's office told the New York Times.
They were not charged with any wrongdoing, but they did not receive the vaccine.
Florida has vaccinated about 42 percent of its population over the age of 65, health care workers, nursing staff and people deemed extremely vulnerable to the virus.
The state has not yet said which group it will prioritise for the next rollout of vaccines.
"Our job as a health department is to vaccinate as many people as possible, as fast as possible," Dr Pino said.
