LOS ANGELES – When the first doses of COVID-19 vaccines were rolled out in the United States, the choice of who should receive them was fairly obvious – and widely accepted.

They would go to healthcare workers, who are highly exposed to the coronavirus and keep the medical system functioning, and people living in nursing homes, who have made up a third of all COVID-19 deaths nationwide.

Since then, the choices have gotten tougher: Teachers, farmworkers, senior citizens and dozens of other groups have made compelling arguments for why they should go next. For leaders making those decisions, it is effectively a zero-sum game: giving priority to some means fewer doses for others.

Though the nation’s vaccine availability will probably improve substantially in the coming months, officials at this moment are wading through what could be the most contentious phase of the rollout – a collision of relentless demand and constrained supply.

“We’ve got to take care of the most vulnerable,” California Gov. Gavin Newsom said at a recent news briefing when asked about priority for individuals with disabilities and underlying conditions. “I’m committed to do that, but I fear that whatever we do won’t be enough until supply is adequate.”

Desperate attempts to fairly distribute the scant supply have created 48 different vaccine eligibility lists across 50 states, with some giving early access to incarcerated people, hospitalized psychiatric patients or people living in multi-generational households, according to data collected by the Kaiser Family Foundation.

In California, there are as many as 61 more vaccine priority lists, as local health departments are allowed to deviate from Newsom’s rules as they deem appropriate.

“When you get your place in line really ends up depending on where you live,” said Jennifer Tolbert, an author of the Kaiser foundation report. “There honestly are no good decisions when you’re in a situation of so many people needing the vaccine, and just not enough doses.”

At the heart of the debate around how to allocate vaccines is a conundrum: Should scarce vaccine be given to one young person, say a supermarket cashier who interacts with hundreds of people a day, because that may protect five elderly people from being infected? Or should the vaccines go directly to five elderly people?

Leading public health experts disagree about how to answer that question. Yet state and local officials face the daunting task of providing a solution that balances science and politics in a way that is equitable and practical.

The nation’s vaccine supply may be abundant in a few months, but for now, when there are only so many lifeboats to go around, some people are bound to be harmed by being left onboard.

“I so regret having to think about it as an either-or,” said Dr. Eve Glazier, president of the Faculty Practice Group at UCLA Health.

In December, as the U.S. vaccination rollout began, the U.S. Centers for Disease Control and Prevention released recommendations for how states should allocate the doses.

They advised vaccinating healthcare workers and long-term care facility residents first. Thirty states followed the guidance exactly, while the others tweaked it by adding police, teachers and other groups.

Next the CDC recommended vaccinating people 75 and over and front-line essential workers, such as grocery store workers, postal workers and teachers. But as states prepared for those vaccinations, federal officials on Jan. 12 called on them to immediately offer shots to everyone 65 and above.

“That as much as anything explains why there is so much variation,” Tolbert said.

Many states, including California, soon expanded access to vaccines to all seniors, a move that came at the expense of essential workers who were supposed to be next in line. In L.A. County, vaccinations for teachers, grocery store workers and law enforcement will not begin until Monday, though people 65 and older have been able to make vaccination appointments for weeks.

Tolbert said that the push to expand vaccinations to people 65 and older was probably an attempt to speed up the slow rollout, since it is simpler  to verify age than job status.

And it may be a reflection of where the country was in January – in the midst of a devastating and deadly COVID-19 surge. Protecting people most likely to die from COVID-19 felt particularly urgent, she said.

But unpredictable vaccine allotments have prevented states from moving on to the next tiers as quickly as they may have hoped. California has received just three-quarters of the vaccine doses that officials initially expected by the end of February and has fully immunized less than 6% of its population.

The CDC had a strong argument for wanting to vaccinate essential workers quickly, some experts say. Though counterintuitive, vaccinating people who may be healthier but more likely to spread the disease can better curb transmission than vaccinating those most likely to die, experts say.

Though the vaccine trials found that the shots significantly reduce deaths and hospitalizations, scientists are studying whether the vaccines reduce transmission of the virus as well. Many experts believe they do.

In an analysis released this month, Rand Corp. researchers found that vaccinating the 15% of the population that has the fewest contacts, such as the elderly who mostly stay home, reduced new infections in a society by 1%, compared to a 96% reduction in infections following a vaccination plan that targeted the 15% of the population with the most contacts, such as essential workers.

“This strategy has the potential to reduce the spread of the virus so radically that everyone, including the vulnerable, will be safer,” the Rand researchers wrote. “People should be vaccinated not so much to protect them, but to protect others from them.”
