In Germany, Lutheran pastors are offering covid-19 shots inside churches. In Israel's science-skeptical ultra-Orthodox community, trusted rabbis are trying to change minds. And in South Africa, undertakers are taking to the streets to spread the word.
The funeral directors' message: "We're burying too many people.''
A year after the covid-19 vaccine became available, traditional public health campaigns promoting vaccination are often going unheeded. So an unconventional cadre of people has joined the effort.
They are opening sanctuaries and going door to door and village to village, touting the benefits of the vaccines and sometimes offering shots on the spot.
As the outbreak drags on into a third year, with the global death toll at 5.4 million, vaccine promoters are up against fear, mistrust, complacency, inconvenience and people who simply have bigger worries than covid-19.
On a December day, a convoy of hearses with sirens wailing drove up to a shopping mall in Johannesburg's sprawling Soweto township.
"Vaccinate, vaccinate!'' Vuyo Mabindisi of Vuyo's Funeral Services said as he handed out pamphlets on how to avoid covid-19. "We don't want to see you coming to our offices."
Several people responded with curiosity and questions, while others carried on with their shopping.
With a population of 60 million, South Africa has reported 3 million-plus covid-19 cases, including over 90,000 deaths. Those are the highest figures in Africa. Only about 40% of South Africa's adult population is fully vaccinated, and that is one of the best levels on the continent. After a fitful start, there is ample vaccine.
Thabo Teffo, a 32-year-old bank employee, was among those seeking shots recently at a Soweto church.
Teffo said he had been skeptical but came under pressure from his parents and two vaccinated sisters, and also had a recent health scare that turned out not to be covid-19.
"That encouraged me to go ahead and get vaccinated for my peace of mind and to protect my family," he said.
Rupali Limaye, a behavioral scientist who studies global vaccine hesitancy at Johns Hopkins Bloomberg School of Public Health, said community-level efforts may resonate more than impersonal mass media campaigns.
German pastor Christoph Herbst believes giving covid-19 shots in surroundings that feel more familiar than medical settings may help. That's why he and several other Lutheran pastors in the Saxony region contacted an aid group to offer shots inside their churches, despite sometimes violent anti-vaccination protests in recent weeks. Some pastors have been criticized and even threatened.
"We believe that we have a responsibility that goes beyond ourselves," said Herbst, of St. Petri church in the eastern city of Chemnitz. "We're not doctors and we're not professionals. But we have the space and we have volunteers who can organise something like this."
Herbst opened St. Petri's wrought-iron doors on a recent vaccination day and sighed with relief when he saw the long line of people waiting in the cold.
Retirees Hannelore Hilbert and her husband came to get booster shots in time for the holidays.
"Last year's Christmas was really sad. We were all alone," said the 70-year-old Hilbert, who looked forward to celebrating with at least some of her five grandchildren in person — not on Skype, like last year.
The Western-made vaccines have proved extraordinarily safe and remarkably effective overall at preventing covid-19 deaths and hospitalisation's, and experts say that seems to be holding true even amid the spread of the highly contagious omicron variant. Health authorities warn that low vaccination rates are giving the virus more opportunities to mutate into new variants.
Saxony has Germany's lowest vaccination rate and high covid-19 numbers.
Herbst said many naysayers are concerned about possible side effects, feel they are overly pressured by authorities, or resent any measures supported by the government. Some feel discriminated against as East Germans, because not all their hopes have been fulfilled 30 years after communism's collapse.
"It's important that there's a space where we listen to each other without immediately lapsing into condemnation," Herbst said.
Chicago community activist Caesar Thompson uses that same approach as he knocks on doors in struggling Black neighbourhoods hit hard by the virus.
Thompson, 44, is a "vaccine ambassador'' enlisted by city health authorities. He said the idea is not to strong-arm or cajole. Instead, he said, he offers information, answers questions and lets people know he can sign them up to receive shots in their homes or nearby.
Thompson has a salesman's gift of gab, and he has used it at churches, train stations, parks, flea markets — almost anywhere people gather.
Thompson said it helps that he's "just a guy on the street." "You might even know me if you live in my neighbourhood," he said.
In communities he targets, the coronavirus is often not the most pressing concern, Thompson said. For people in crime-ridden neighbourhoods who lack jobs or health insurance and are struggling to feed their families, "covid is down the list for them," he said.
In conservative Wyoming, the vaccine can be a hard sell. Commissioners in Campbell County voted against using federal dollars for an education campaign about the vaccines, worrying that it would smack of a mandate. The county's vaccination rate is about 27%.
Gabby Watson, 23, of Gillette, said she has no intention of getting vaccinated "because I'm really healthy and take care of myself. I'm just not a high risk for covid. I just don't see the reasoning for me to get the vaccine."
She said the U.S. government is pushing covid-19 vaccines too hard.
"They're pushing more people away and creating more of this thought bubble of, 'What the hell are you trying to do with my body? What are you trying to do with my freedom?'" Watson said. "And that's not a good direction to go into either."
Suspicion of secular authorities is rampant in Israel's community of ultra-Orthodox Jews, They shun many trappings of modern life, follow a strict interpretation of Judaism and rely on rabbis to guide many life decisions. While some rabbis have encouraged vaccination, others have taken a less aggressive approach.
The ultra-Orthodox have some of Israel's lowest vaccination rates and have been hit hard by the pandemic.
Now, facing omicron, Israeli officials "are going on the offensive,″ said Avraham Rubinstein, the mayor of Bnei Brak, the country's largest ultra-Orthodox city. They are deploying mobile vaccination clinics and enlisting prominent rabbis in the community.
Yossi Levy, a 45-year-old ultra-Orthodox Jew, recovered from the virus earlier this year, as have his eight children and wife. He has repeatedly booked and canceled covid-19 vaccine appointments.
"It isn't something pressing. I'm not opposed to it. It's just laziness," Levy said.
While Israel's vaccination rates for the second dose among the general population hover around 63% and the booster at 45%, in the ultra-Orthodox community the numbers are around half of that.
The ultra-Orthodox — 13% of Israel's population — tend to live in crowded neighbourhoods, with large families in small apartments, where sickness can spread quickly. Synagogues, the centerpiece of social life, bring men together in small spaces. Also, half of that population is under 16 and only recently became eligible for vaccination.
Gilad Malach, who heads the ultra-Orthodox program at a Jerusalem think tank, said there is a "double fear: fear of the state and fear of science. There is no basic trust in these entities.''
In India, complacency is contributing to a low rate of second shots among the population of 1.4 billion: 40% are fully vaccinated and around 19% have received just one shot.
The country has recorded nearly 35 million cases and over 450,000 deaths.
In Uttar Pradesh, India's most populated state, Rohit Kanojia received his first shot in August but didn't get the second one.
"I forgot," the 23-year-old said, adding that people are no longer afraid of covid-19. People roam around without masks and no one maintains social distance, he said. "Life is almost normal."
Jeet Bahadur, a 45-year-old cook, got his second shot months late at a Sikh temple in New Delhi. For him, like many others in India who are trying to eke out a living in a crippled economy, the virus just wasn't very high on his list of priorities.
At least 53 were killed and about 200 wounded, Gaza’s Civil Defence agency said.
