US Health Secretary Robert F. Kennedy Jr. told American parents to get their children vaccinated against measles on August 2, 2026, during an interview with CNN's State of the Union. His remarks came as the US measles surge reached numbers not seen in 35 years, with 2,371 confirmed infections recorded so far in 2026, surpassing the 2025 total of 2,289 The Guardian. The last year with a higher recorded caseload was 1991. The past two years have seen more measles infections in the US than the rest of the 21st century combined.

Kennedy's vaccination call came after CNN host Dana Bash invited him to use his 'bully pulpit' — meaning his platform as a senior official — to speak directly to parents ahead of the new school year. 'Parents should get their children vaccinated for measles. A measles vaccine is effective, it stops measles in about 97% of the cases. People should get vaccinated,' Kennedy said The Guardian. He later added that people should also get the combined measles, mumps, and rubella (MMR) vaccine. Kennedy also told Bash that he has 'never questioned the efficacy of the MMR' vaccine CNN.

The 37 new measles outbreaks recorded in 2026 put the US in danger of losing the measles elimination status it has held since 2000 The Guardian. Elimination status means a disease is no longer continuously spreading within a country. The disease has claimed the life of a school-aged child, according to an earlier HHS press-room statement titled 'Measles Outbreak is Call to Action for All of Us,' in which Kennedy also said the MMR vaccine is crucial to avoiding potentially deadly measles disease HHS. At least 700 of the 2,289 confirmed cases in 2025 were associated with a large West Texas outbreak CIDRAP.

The exchange between Kennedy and Bash grew tense. Kennedy accused Bash of 'saying nonsense,' 'repeating like a parrot,' and 'making assertions you can't support,' and said she had become 'flustered' The Guardian. Bash responded, 'I am frustrated because you are the HHS secretary and you are talking about things that lead to vaccine hesitancy in this country.' Asked whether he took any responsibility for the measles surge, Kennedy said, 'Absolutely not.' He blamed the outbreaks on religious communities who eschew vaccines and on global health conditions The Guardian. Kennedy told Bash that 'The communities that are suffering from measles are almost all religious communities that just don't vaccinate' CNN.

The broader context here is one of conflicting institutional signals from HHS and a documented decline in childhood vaccination rates. Reuters reported that Kennedy has repeatedly promoted the claim that measles vaccines are linked to autism despite overwhelming scientific evidence to the contrary Reuters. Kennedy and his advisers debated eliminating the MMR shot in the fall, according to three people cited by Reuters Reuters. A Reuters data analysis showed child vaccination rates dropped sharply in Michigan under Kennedy's influence, with a swift fall in inoculations of toddlers Reuters. A September 2025 CNN analysis reported that Kennedy showed some support for measles vaccines but also called them a 'personal' choice CNN. Oklahoma Republican Sen. James Lankford, in a March 2025 State of the Union appearance, urged people to get vaccinated against measles while downplaying concerns over Kennedy's handling of the outbreak CNN.

HHS's immunization guidance states there are two vaccines that can prevent measles: the MMR vaccine and the MMRV vaccine, which also protects against chickenpox HHS. The CDC's Advisory Committee on Immunization Practices (ACIP) recommends all children receive immunizations for measles, mumps, rubella, and chickenpox from 12 months of age HHS. HHS's rubella guidance states the MMR vaccine protects children and adults from rubella, including birth defects that last a lifetime HHS. In a December 2025 press-room statement titled 'HHS Protects Parents' Rights in Children's Health Decisions,' Kennedy said providers should not ignore parental consent, violate exemptions to vaccine mandates, or keep parents in the dark about their children's health HHS.

Looking at what this means for US public health policy, the trajectory of the outbreak places the country's elimination status in direct jeopardy. The confluence of rising caseloads, declining toddler inoculation rates, and internal debates over the MMR shot's availability creates an environment where the August 2 vaccination call, while authoritative on its face, competes with prior rhetoric and policy postures that medical professionals and journalists like Bash identify as drivers of hesitancy. The friction between Kennedy's assertion that he has 'never questioned the efficacy of the MMR' vaccine and his documented promotion of debunked autism claims frames the core stakes for institutional credibility at HHS heading into the school year.
