The Big Question: Can a Covid Vaccine Reach Enough People?

(Bloomberg Opinion) -- This is one of a series of interviews by Bloomberg Opinion columnists on how to solve today’s most pressing policy challenges.

Max Nisen: The U.S. is going to have to vaccinate hundreds of millions of people in a short amount of time to bring Covid-19 under control. Various logistical and political challenges complicate that goal. The virus response hasn’t been the best advertisement for America’s public-health infrastructure. Does the country have to start from scratch, or are there existing systems the U.S. can rely on?

Dr. L.J. Tan, Chief Strategy Officer of the Immunization Action Coalition: When H1N1 hit in 2009, we already had a very strong pediatric infrastructure because of Vaccines for Children, the public-private sector partnership to administer vaccines. Our coverage rate in peds is over 95%. The problem is that the adult infrastructure was not in place.

We hadn’t really done as well at vaccinating adults, and that’s not to say we’re doing well now. But the private sector, which is where adult immunizations reside, is actually much more cognizant of the importance of adult vaccines as a result of the last 10 years of effort.

Many health systems have implemented infrastructure to give access to adult vaccines. Some of those are things we’ve talked about for Covid-19, like facilitating vaccinations at alternative locations, using pharmacists, drive-through clinics, no appointment necessary walk-in clinics, occupational health. These are things that were really not looked at 15 years ago but are now becoming commonplace because of the innovations of these systems.

Sometimes when we’re reacting to a crisis we can become a little short-sighted. There is an existing infrastructure that can get vaccines all across the lifespan to the U.S. population. It’s stronger in pediatrics, weaker for adults, but it is an infrastructure that we should not have to reinvent.

MN: How do you prioritize what’s likely to be a limited early supply of vaccine? And after that, how do you avoid the racial and economic disparities that have plagued the Covid response?

LT: We asked almost exactly the same question for H1N1 and during our flu pandemic planning in the mid-2000s. Flu has similar vulnerable populations as Covid-19. In our entire seasonal flu efforts, we have had racial disparities in getting people vaccinated.

With Covid-19, we’ve seen that we have problems with access to health care. But it’s not as if we weren’t previously aware of those kinds of problems.

For pandemic planning [during the H1N1 outbreak], we had a large working group of experts from both the National Vaccine Advisory Committee and the Advisory Committee on Immunization Practices meet very regularly to come up with a priority list for vaccination. It had five tiers. The first tier was health-care workers. We then had the elderly as the next camp, over children. When we went to do a couple of quick focus groups, it became very clear that the elderly, the grandparents, were not going to take the vaccine ahead of their grandchildren. And so, as a result of that feedback, the priority populations were flipped. Children went up because we have to recognize that there’s an ethical and social component to consider.
