US President Joe Biden’s announcement last week that Anheuser-Busch InBev would be donating beer was the latest attempt to bribe Americans hesitant to get vaccinated. Other officials wielded empanadas, guns, and even stumbling cash.

While the administration aims to get at least one shot at 70% of Americans by July 4, the gimmicks seem to be working.

Vaccinations increased last month among young people typically targeted by the campaigns. About 44% of 18 to 24 year olds have now received at least one injection, up from 34% a month earlier.

The incentives aren’t getting all the credit – in some states this age cohort only recently became eligible – but experts say they’re helping, especially among those on the fence. In some ways, the demographics are already exceeding expectations: As recently as February, a KFF COVID-19 Vaccine Monitor poll indicated that short-term vaccine penetration among young people would not increase much above 40 %.

COVID-19 cases and deaths are plunging across the country, and many state economies have started to temporarily return to normal. But epidemiologists say the improvement partly reflects the seasonal patterns of the virus, and the vaccination campaign must move forward to mitigate the rapidly spreading variants and the threat of a winter resurgence.

One of the keys to how effective the incentives are is that they have been personalized, said Austin Hall, a University of North Carolina psychiatrist who has worked to ease the hesitations of patients with severe mental illness.

“The more diverse the incentives offered, I think we can attract that many people,” Hall said.

At least half a dozen states have introduced some form of lottery with cash prizes for newly vaccinated people. In Washington State, you can win game consoles and smart speakers. West Virginia can get custom pickup trucks and shotguns. Several states offer scholarships. Gift venues include trendy Miami bars, hair salons, and street parties.

California authorities last week announced prices of $ 116.5 million to encourage residents to get vaccinated before the state’s official reopening date of June 15. On Friday, the state selected the top 15 winners of $ 50,000 in cash prizes as part of the new “Vax for the Win” campaign.

In Chelsea, a predominantly young and Latino town near Boston that has been one of Massachusetts virus hotspots, health officials held a vaccination party in late May attended by 120 people, filled with music. and Latin American dishes like empanadas and pupusas. They plan to follow up so that participants can get a second photo.

The parties reflect widespread efforts, from door-to-door visits to mobile vans, which have pushed Chelsea’s partial vaccination rate to about the state average. The city is working with local nonprofits to encourage vaccination, catching young people where possible, said city manager Tom Ambrosino.

“We show up with mobile vaccination vans to some of our crowded parks where children play football on weekends,” he said. “You could catch 20 or 30 people – every little bit counts. “

Hall, the psychiatrist, said it will take a lot more than crispy empanadas to persuade even the most hesitant Americans. Its Center of Excellence for Community Mental Health helps patients with conditions such as schizophrenia, many of whom are predisposed to paranoia and already have unusually low levels of immunization.

“Exploring their reasons for hesitation is healthier and more productive than simply dismissing their concerns as being under-informed or under-educated,” he said. “Conversations rather than conferences, especially with a health care provider, work much better. “
