Robert F. Kennedy Jr., the brand new head of the U.S. Division of Well being and Human Providers (HHS), has lengthy forged doubt on the protection of vaccines—notably the one for measles, mumps, and rubella (MMR). However in his new opinion piece concerning the ongoing measles outbreak, revealed March 2 in Fox Information, Kennedy wrote that vaccines “not solely shield particular person kids from measles, but additionally contribute to neighborhood immunity, defending those that are unable to be vaccinated on account of medical causes.”
Kennedy’s acknowledgement of the worth of the measles vaccine comes because the outbreak that started in Texas continues to develop. Up to now, practically 150 circumstances and one demise—the primary U.S. fatality from the illness in additional than 10 years—have been confirmed. It is the biggest measles outbreak within the U.S. in a long time.
When Kennedy beforehand mentioned the outbreak at a cupboard assembly final week, he didn’t point out vaccination.
Nonetheless, within the Fox piece, Kennedy additionally wrote concerning the significance of food plan in defending individuals from measles—an element that consultants say will not be very related for Individuals. “Good vitamin stays a finest protection in opposition to most power and infectious illnesses,” he wrote. He additionally touted vitamin A for individuals with measles. On Feb. 27, the U.S. Facilities for Illness Management and Prevention, which HHS oversees, up to date their steering to say that whereas there isn’t a antiviral remedy for measles, “supportive care, together with vitamin A administration underneath the course of a doctor, could also be acceptable.”
This is what consultants take into consideration Kennedy’s first main public communication in his new function on the helm of the highest U.S. well being company.
A (certified) endorsement of vaccination
Kennedy acknowledges what public-health consultants have lengthy maintained: that the easiest way to manage measles is to vaccinate the general public and provides them immunity to the virus. Of the 146 circumstances reported thus far, state well being officers say 79 individuals weren’t vaccinated in opposition to MMR.
However whereas he concedes the significance of population-level vaccination to be able to obtain community-wide safety, he additionally maintains that “all mother and father ought to seek the advice of with their healthcare suppliers to grasp their choices to get the MMR vaccine. The choice to vaccinate is a private one.”

Sadly, herd immunity does not work that approach, public-health consultants say. Neighborhood-level safety—in any other case often known as herd immunity—isn’t doable except upwards of 90% of persons are immunized. Specialists agree that balancing private selection and the scientific actuality of herd immunity is important for holding outbreaks underneath management.
“The issue with making well being choices like vaccination on a person degree is that viruses do not see us as people,” says Ben Neuman, professor of biology at Texas A&M College. “[They] see humanity as a bunch. And as soon as the virus will get into considered one of us, the possibilities are higher that it will get into one other particular person.” Neuman describes vaccination in opposition to illnesses like measles as “mainly an ethical duty of dwelling in a contemporary democracy. Treating [the decision to get vaccinated] as a person liberty is basically irresponsible, in a public-health sense.”
“It’s necessary as public-health consultants that we do our greatest to convey to the inhabitants at giant why it’s so necessary that we proceed to have this shared obligation for one another’s well being,” says Dr. Daniel Kurtizkes, chief of the division of infectious illnesses at Brigham and Ladies’s Hospital. “Sure, definitely, particular person liberty is a vital American worth, nevertheless it must be put in context: we don’t have the suitable to do all the things we’d need to do. We’ve some obligation to do sure issues we’d not in any other case need to do as a result of it protects different individuals.”
A troubling emphasis on vitamin A and food plan
Whereas infectious-disease consultants are gratified that Kennedy is acknowledging the efficacy of vaccines and the significance of herd immunity, they’re involved about his emphasis on vitamin A. “Vitamin A just isn’t a particular remedy for measles,” says Kuritzkes.
In elements of the world the place kids will not be getting sufficient vitamin A of their food plan, the deficiency can enhance their danger of extra extreme illness and problems from measles. However, says Dr. Tina Tan, professor of pediatrics on the Feinberg College of Medication at Northwestern College and president of the Infectious Illness Society of America, that doesn’t imply that vitamin A is a backup for vaccination. “I don’t need individuals studying about this to assume, ‘I don’t must get vaccinated, I’ll simply get vitamin A.’ It doesn’t work like that.”

The research supporting the advantages of vitamin A for individuals with measles come largely from the growing world, the place individuals sometimes don’t get sufficient of the vitamin of their food plan. The deficiency can result in weaker immune responses, in addition to different well being points comparable to blindness and delayed development. These research present that supplementing with vitamin A in people who find themselves poor can result in milder infections with illnesses like measles.
However there may be little proof that it could make a big distinction in individuals who have already got wholesome ranges of the vitamin, as is the case within the U.S. “In a rustic just like the U.S. the place vitamin A deficiency is awfully uncommon, it could be stunning if supplementation produces any measurable scientific profit,” says Kuritzkes. “It’s definitely not a substitute for measles vaccination.”
Supplementing with the vitamin may cause critical well being issues if it’s not carried out correctly, Kuritzkes says. An excessive amount of vitamin A can result in the poisonous results of hypervitaminosis A, which causes nausea, joint ache, bone fractures, and liver injury, amongst different signs. The situation has been described in Indigenous individuals who consumed polar bear livers, which have excessive concentrations of vitamin A.
Tan says that some docs within the U.S. do give measles sufferers the vitamin, however provided that they imagine the affected person could also be poor. “We noticed quite a lot of youngsters in the course of the measles outbreak within the immigrant facilities right here in Chicago, and there was no approach of realizing upfront what the vitamin A ranges had been in these youngsters, so we simply gave them dietary supplements,” she says. However she and Kuritzkes say it’s a mistake to self-treat with off-the-shelf nutritional vitamins. Doing so is probably going a waste of time and money, they are saying; it most likely gained’t do a lot to mitigate the an infection and might be poisonous if utilized in extreme quantities.
Kennedy’s message doesn’t make clear during which teams vitamin A supplementation could be most helpful or acceptable: simply that “research have discovered that vitamin A can dramatically cut back measles mortality.” He goes on to debate the significance of excellent vitamin as a “finest protection in opposition to most power and infectious diseases.”
Whereas correct vitamin is important for establishing a robust basis to struggle any illness, it will not make you invincible to viruses and pathogens. “The one strategy to shield your self in opposition to measles is to get vaccinated,” says Tan. “The most effective preventive technique is to stop someone from getting the illness within the first place by vaccinating them.”
