NASHVILLE — Public health departments have held vaccine clinics at churches. They have organized rides to clinics. Gone door to door. Even offered a spin around a NASCAR track for anyone willing to get a shot.
Still, the United States’ vaccination campaign is sputtering, especially in the South, where there are far more doses than people who will take them.
As reports of new Covid-19 cases and deaths nationwide plummet and many Americans venture out mask-free, experts fear the virus could eventually surge again in states like Alabama, Louisiana and Mississippi, where fewer than half of adults have had a first shot.
“I don’t think people appreciate that if we let up on the vaccine efforts, we could be right back where we started,” said Dr. Jeanne Marrazzo, the director of the Division of Infectious Diseases at the University of Alabama at Birmingham.
A range of theories exist about why the South, which as of Wednesday was home to eight of the 10 states with the lowest vaccination rates, lags behind: hesitancy from conservative white people, concerns among some Black residents, longstanding challenges when it comes to health care access and transportation.
The answer, interviews across the region revealed, was all of the above.
“There’s no magic bullet. There’s no perfect solution,” said Dr. W. Mark Horne, president of the Mississippi State Medical Association.
Time is of the essence, both to prevent new infections and to use the doses already distributed to states. Coronavirus variants are spreading, especially the highly transmissible and increasingly prevalent Delta variant, first detected in India. And millions of Johnson & Johnson vaccine doses will expire nationwide this month, prompting some governors to issue urgent pleas that health providers use them soon.
From rural Appalachia to cities like Birmingham and Memphis, the slowdown has forced officials to refine their pitches to residents. Among the latest offerings: mobile clinics, Facebook Live forums and free soccer tickets for those who get vaccinated.
RIO DE JANEIRO — Officials at the World Health Organization on Wednesday repeated their calls for the world’s governments to accelerate plans to distribute coronavirus vaccines to hard-hit nations, warning that many countries in Latin America continued to see rising caseloads.
“Across our region, this year has been worse than last year,” said Dr. Carissa F. Etienne, the director of the Pan American Health Organization, which is part of the W.H.O. “In many places, infections are higher now than at any point in this pandemic.”
The comments came as President Biden prepared to announce that his administration would buy 500 million doses of the Pfizer-BioNTech vaccine and donate them among about 100 countries over the next year, according to people familiar with the plan. Mr. Biden could announce the arrangement as early as Thursday, as he begins his first trip abroad as president.
It is not yet clear which countries the 500 million vaccine doses would be supplied to, but Latin America is among the regions where the need is urgent. Eight of the 10 countries with the highest rate of Covid deaths per capita are in Latin America and the Caribbean, according to the Center for Systems Science and Engineering at Johns Hopkins University.
And even as hospitals in Argentina, Chile, Uruguay and other nations where the virus continues to spread aggressively have created overflow facilities, health care systems in several nations in the region are struggling to cope, Dr. Etienne said during the W.H.O.’s virtual news conference on Wednesday morning.
“Despite the doubling or even the tripling of hospital beds throughout the region, I.C.U. beds are full, oxygen is running low and health workers are overwhelmed,” she said.
Most governments in Latin America are struggling to acquire enough doses to quickly inoculate their people, which will delay their ability to fully reopen economies, officials said.
Last week, Mr. Biden said that the United States would distribute 25 million doses this month to countries in the Caribbean and Latin America; South and Southeast Asia; Africa; and the Palestinian territories, Gaza and the West Bank. Those doses are the first of 80 million that Mr. Biden pledged to send abroad by the end of June.
Dr. Etienne said that only a more equitable distribution system would put an end to the pandemic in the foreseeable future.
“Today we’re seeing the emergence of two worlds, one quickly returning to normal and another where recovery remains a distant future,” Dr. Etienne said. “Unfortunately, vaccine supply is concentrated in a few nations while most of the world waits for doses to trickle down.”
She singled out the vaccine shortage in Central America, home to more than 44 million people, where just over two million have been inoculated. Fewer than three million people have been vaccinated in nations in the Caribbean, which has a population of just over 34 million.
A Nevada man accused of stealing more than 500 blank Covid-19 vaccine cards from the Los Angeles vaccination site where he worked was charged on Wednesday with one felony count of grand theft, according to the Los Angeles County District Attorney’s office.
The man, Muhammad Rauf Ahmed, 46 of Las Vegas, had been arrested in April, but the charge was delayed as the police and prosecutors sought to determine the value of the cards, which was eventually judged to be “at least $15 apiece if illegally sold.”
Around the country, many bars, restaurants and businesses that operate under limited capacity have loosened restrictions for people who can prove that they have gotten the vaccine, creating an underground market for doctored or fraudulent vaccine cards.
In January, fake vaccine cards were being sold on eBay, Etsy, Facebook and Twitter, ranging in price from $20 to $60. In May, a California bar owner was arrested on charges that he sold fake vaccine cards for $20 a piece.
Mr. Ahmed was a nonclinical contract employee hired to work at the vaccination site at the Los Angeles County Fairgrounds, where nearly 4,000 vaccines are administered daily, the La Verne Police Department, in eastern Los Angeles County, said in a statement on Tuesday.

On April 27, the department was contacted after a security guard at the site spotted Mr. Ahmed leaving with a batch of the distinctive cards in his hand, Detective Sgt. Cory Leeper said in an interview on Wednesday.
Eventually, two staff members from the vaccination site confronted Mr. Ahmed at his car, the detective sergeant said. Mr. Ahmed told them that he liked to go to his car on his break and on that day, sought to “pre-fill” the cards with information that went to every recipient in order to get ahead of his workload, the detective sergeant said.
Officials recovered 128 cards from Mr. Ahmed’s vehicle, according to the police, and when questioned further, Mr. Ahmed acknowledged that he may have taken additional cards. The police found 400 blank cards in the hotel room where he was staying. Mr. Ahmed was arrested. Efforts to reach him by telephone on Wednesday were not successful.
“Selling fraudulent and stolen vaccine cards is illegal, immoral and puts the public at risk of exposure to a deadly virus,” George Gascón, the district attorney in Los Angeles, said in a statement on Wednesday.
