When pollsters said there was no more Americans who would be willing to be vaccined against the coronaviruses, Coral Garner continued to find them.

She arranged to provide vaccines and booster shots to people who had resisted them, setting up in a retrofitted city bus outside a Nigerian church and dozens of other places.

Even as the United States prepares for a critical campaign to deliver Omicron-specific booster shots, Ms. The state said that funding had dried up.

Local programs to bring shots to the places where Americans gather and the institutions they trust have folded as a result of congressional resistance to more pandemic response spending.

The same local health department workers responsible for Covid and flu shots this fall have also been juggling a monkeypox outbreak and childhood immunizations that have left some places vulnerable to the disease.

State health officials said in interviews that they had stopped pushing coronaviruses shots because of weak demand and increased survival rates.

The country's no-expenses-spared attitude to saving lives has evolved into a response that requires individuals to protect themselves. Many health officials believe the vaccine machinery is in place to meet what they expect to be modest demand this fall.

The country is surrendering a decisive opportunity to stoke that demand and restore the more robust vaccinations that lifted last year's initial roll out.

Stephen Thomas is the director of the Center for Health Equity at the University of Maryland. It's embarrassing that vaccine take-up in the US is so low.

The Biden administration said that many sites would be ready to give the vaccine this fall. Doctor's offices, community health centers, and rural health clinics are included.

Setting up sites, buying equipment, and offering translation or transportation are some of the things states can ask for money for from the Federal Emergency Management Agency.

States have been promised FEMA reimbursements on a relatively modest $550 million in vaccine spending so far this year. It was $8.5 billion last year.

The federal government ran out of money this spring to offer reimbursements for shots for uninsured people, making it more difficult for them to get booster shots.

Sonya Bernstein is a senior policy adviser for the White House Covid response team. Some state health officials say that the Republicans' claim that additional coronaviruses could be covered with funding already approved by Congress is false.

Ms. Bernstein said that Congress hasn't provided them with the funding they need. That has not interfered with our preparation. We are working around the clock to make sure states and our partners have the resources and support they need.

At a time when health officials are pulling back on other preventive measures, the U.S. is leaning more heavily on vaccines to defend against the virus.

The vaccine campaign is expected to start after Labor Day. Up to 165,000 Covid deaths are expected by the spring as more indoor gatherings are on the horizon.

For the first time, the government has bought vaccines that were reformulated to fight the virus. The Omicron subvariant that the updated shots were designed to protect against remains dominant in the US.

The vaccine campaign is lagging. Only a small percentage of Americans have received boosters for the primary vaccine series. According to Our World in Data, the country's per capita booster coverage lags behind many other nations.

According to scientists, Americans have died from Covid at a higher rate than Canadians and Europeans.

According to Elizabeth Wrigley-Field, a University of Minnesota sociologist, there was a lot of effort to get everyone to get the vaccine. There isn't that with boosters.

With Covid deaths having stopped, policymakers are wondering if renewed investments are needed. Some states don't think they're not.

In Alabama, where one-fifth of the population is boosted, the medical officer for disease control and prevention said that officials had scaled back health department clinics. She said that the decision to get more shots was up to the individual.

We aren't doing a hard push at this point. There is a personal decision.

The wall of complacence has run into some more proactive efforts. In Camden County, N.J., health workers have visited community events and knocked on doors, but they haven't seen as many people as they would have liked.

Other health workers said that they were still winning converts even if it was less than last year.

A former police officer who runs a health clinic in Madison, Wis., said that the $100 stipends given by the state helped him attract a dozen or so booster recipients to his clinic every Friday.

As many as 30 first dose recipients can still be found in San Bernardino, Calif., according to a pharmacy professor.

In North Dakota, the public health director said that homeless shelters and food pantry still wanted to host regular clinics. She said she could only hold monthly pop-up clinics at a limited number of sites because she couldn't find enough workers.

According to Dr. Thomas, of the University of Maryland, nine out of 10 barbershops that used to host vaccination events are now struggling to keep their doors open. Hospitals that used to send doses have reported not having the money to partner with barbershops again or being worried that small turnouts will not make it worth their time.

Mike Brown said that the health care providers lost interest in him. The time is not right to give up the fight. The people are dying.

The decrease in public vaccine sites could affect the number of people who receive shots.

In New York, Emily Gerteis, who arranges shots for people living on the street or in shelters at the Center for Urban Community Services, recalled persuading a patient to be vaccine free. The patient refused to go to a pharmacy when Ms. Gerteis suggested it.

The problem was that those offerings were no longer around. The patient didn't have a vaccine.

A doctor in Minneapolis who helped organize vaccinations at his local barbershop until funding dried up said that a year ago there was all this money for advertising and they were throwing money at vaccines. It is like no one cares.

The White House wants Congress to give it more money so it can produce tests and develop next- generation Covid vaccines.

Some health officials said they were prepared to reopen shuttered sites in the event of a surge in demand. The health commissioner in Columbus, Ohio said she needed to divert two-thirds of her vaccine specialists to monkeypox clinics.

She said that it was a bit overwhelming for some of them.

The boom-and-bust cycle in public health spending can be broken by restoring health workforces and maintaining vaccine outreach. Race gaps in primary series vaccine rates were narrowed by early investments. There have been racial differences re-emerging.

Some health officials said that the relaxation of federal Covid guidance did not make it any easier to convince people of the benefits of booster shots.

West Virginia's Covid czar said that there is a lot of messaging from federal sources that things are good. It is mixed message.

Making Covid shots a regular part of people's medical care was encouraged by health experts. A professor at a university said that more creative marketing can help generate demand.

He said there would be a campaign to protect older relatives at holiday gatherings. Despite the scientific uncertainties, he also said the time had to come to promise Americans that they would not be asked back for further Covid vaccines for at least a year, and that, when they were, it would be for an "annual Covid vaccine" instead of a "booster

Dr. Schulman said that marketers spent a lot of time trying to figure it out. Efforts haven't been devoted in that direction.

Ms. Bernstein said that the administration used the results of the surveys to suggest messages to on-the-ground partners.

Ben Weston, Milwaukee County's chief health policy adviser, said the nation's underfunded booster campaign had hurt vulnerable and often nonwhite residents who have long struggled to get access to good medical care.

He said that it was putting up barriers for populations that were more vulnerable.
