Dr. Oz says MMR is "not a lethal vaccine" despite Trump's comments

Oz Addresses Trump's Remarks on National Television

Dr. Mehmet Oz, administrator of the Centers for Medicare and Medicaid Services, stated on Sunday that the measles, mumps and rubella vaccine is not a lethal vaccine. Speaking on CBS's Face the Nation, Oz made the comment after host Margaret Brennan pressed him repeatedly to address remarks by President Donald Trump.

As reported across CBS News, HuffPost, Newsweek, the New York Post and The Daily Beast, Brennan played a clip of Trump and asked Oz to clarify the president's use of the word "lethal." Oz initially emphasized parental autonomy and the desire for Americans to follow doctors' recommendations when they have a choice. After further questioning, he said: "The MMR vaccine is not a lethal vaccine."

Oz added that the vaccine is offered separately in other countries, citing Japan as an example, and framed the discussion around parents' rights to ask questions. He said Trump wants people "to get vaccinated as their doctors recommend, as long as they have a choice in the matter," according to accounts from CBS News and the New York Post.

Context of the Executive Order

Trump signed an executive order on August 10 directing the Department of Health and Human Services to split the MMR vaccine into three separate shots and to space out childhood vaccines. During the signing, Trump said that together the components "could be quite lethal" while separately they appear "not at all lethal, but just very effective." Multiple outlets, including Newsweek and CBS News, reported that Trump offered no evidence for the claim.

The order encourages spacing vaccines into separate appointments to the maximum extent feasible and moves several other vaccines into a high-risk category, Newsweek reported. Oz defended the order on the New York Post's account of the interview, arguing it gives parents more control over their children's immunization schedules. He said CMS would pay for the vaccines regardless and that the core issue is whether parents have the right to ask questions. Oz also noted that many states have not clarified parental choice options, which he said makes it harder for parents to raise concerns.

Availability and Practical Challenges

The MMR vaccine is not currently available as three separate shots in the United States. Merck, the manufacturer of the long-used combination vaccine, has said it could not offer separate shots for at least another 10 years, according to Newsweek, HuffPost and The Daily Beast. Brennan raised this point during the interview, along with noting that Japan experienced problems after separating the shots.

Newsweek reported that Japan banned the combination MMR vaccine in 1993 because a mumps strain was linked to aseptic meningitis in some children; the country later used separate vaccines. Critics have argued that FDA approval of separate measles, mumps and rubella vaccines would take considerable time. The two-shot MMR schedule has been the U.S. recommendation since 1989, the New York Post noted, and the CDC schedule has not changed since the executive order.

Measles Landscape and Public Health Response

The exchange occurs against a backdrop of elevated measles activity. As of August 20, the CDC reported 2,777 confirmed measles cases in the United States, with KFF Health News and Newsweek citing the figure. KFF Health News said the agency added 211 new cases in its weekly update, more than double the prior week's increase, with most of those cases in Pennsylvania and Ohio. Approximately 92 percent of U.S. kindergarteners received the MMR vaccine in the prior school year, below the 95 percent threshold associated with herd immunity, according to Newsweek and The Daily Beast.

Public health groups, including the Partnership to Fight Infectious Disease, warned that the executive order would leave children vulnerable to preventable illness, Newsweek reported. Senator Bill Cassidy, a Republican from Louisiana who chairs the Senate health committee, criticized the order, saying Trump "does not have the expertise to make these changes." Doctors have also raised concerns that the policy could endanger children at a time of prevalent measles, declining immunization rates and the return to school, as noted by HuffPost. Fact-checkers have rejected the claim that the MMR vaccine is lethal, and the CDC has described the vaccine as safe, according to HuffPost.

A Denver-area outbreak of just 10 measles cases cost roughly $500,000 to contain and required more than 6,700 hours of labor, KFF Health News reported, illustrating the resource demands of even limited clusters. The United States is experiencing its highest measles caseload in more than three decades.

Differing Emphases in the Exchange

Oz repeatedly returned to the theme of parental choice and state-level flexibility during the Face the Nation appearance. He said the president's request is to ensure states offer eligibility for exemptions based on religious beliefs or other reasons. At the same time, he rejected the description of the combination vaccine as lethal. Coverage differed in tone and emphasis: some accounts portrayed Oz as correcting or pushing back on the president's language, while others presented him as clarifying the point while defending the broader goals of the executive order.

The combined MMR vaccine has been in routine use for more than 40 years. Major developed countries including the United Kingdom, Canada and Australia maintain similar combination recommendations. Separate antigen vaccines remain unavailable in the U.S. market, and manufacturers have not announced plans to produce them.

Perspectives

Trump administration and Oz: The executive order aims to expand parental control and choice over vaccine timing and components. Oz affirmed that the MMR vaccine itself is not lethal while insisting parents should be able to follow medical advice with meaningful options and that states should clarify exemption pathways.

President Trump: During the August 10 signing, Trump asserted that the combination MMR shot carries a possibility of being "quite lethal" and that separating the components would make them effective without that risk.

Public health groups, physicians and Senator Cassidy: Critics contend the order lacks scientific grounding, could complicate immunization logistics for families, and risks leaving more children unprotected amid rising measles cases and vaccination rates already below herd-immunity levels.
