A brother, sister and niece of Robert F. Kennedy Jr. Wednesday chastised him for campaigning against vaccines, saying he has been disseminating “dangerous misinformation” that discourages immunization even as measles spreads throughout the United States.
They declared that they love him and praised his work to protect the environment. “However, on vaccines he is wrong,” they wrote in a column published in Politico under the headline: “RFK Jr Is Our Brother and Uncle. He’s Tragically Wrong About Vaccines.”
Mr. Kennedy’s sister, Kathleen Kennedy Townsend, a former lieutenant governor of Maryland; his brother, Joseph P. Kennedy II, a former Massachusetts congressman; and his niece, Maeve Kennedy McKean, executive director of Georgetown University’s Global Health Initiatives, criticized him for participating in social media campaigns that have stoked fear and mistrust of vaccines and for attacking public health institutions seeking to stem the spread of infectious diseases.
Mr. Kennedy, an attorney, author and environmental activist, could not immediately be reached for comment. Lara Bono, a spokeswoman for a group he leads, Children’s Health Defense, said Mr. Kennedy was occupied with a court case today but plans to make a statement and respond to questions.
Mr. Kennedy is chairman of the board of Children’s Health Defense. Its website ties the increase in chronic childhood conditions such as asthma, autism and diabetes to a range of factors, including environmental toxins, pesticides and vaccines.
The group links to information and videos that blame vaccines for food allergies, claim that vaccines against diphtheria, pertussis and tetanus are killing people, and charge that media coverage of the current measles outbreak has been “orchestrated” by the World Health Organization.
In their column, Mr. Kennedy’s relatives took a tempered tone for the most part, but noted that researchers have concluded there is no link between vaccines and autism, and that their family has had a longstanding commitment to vaccination as a critical tool for improving public health.
They pointed out that President John F. Kennedy in 1961 urged Americans to take advantage of a new “miraculous” polio vaccine; in 1962, he signed the Vaccination Assistance Act to help ensure all American children were immunized.
“On this issue, Bobby is an outlier in the Kennedy family,” they wrote.
The United States is now experiencing the worst measles outbreak since the disease was declared eliminated in the United States in 2000. As of Monday, 764 cases had been identified in 23 states, most of them in people who were never vaccinated.
Government health officials have made an urgent plea to parents to vaccinate their children if they have not already done so, and they are urging Americans to be immunized before traveling overseas.
Mr. Kennedy’s relatives wrote that his anti-vaccine messages are having “heartbreaking,” and even deadly, consequences.
