As Measles Continues to Rise, CDC Muffles Vaccine Messaging
By burying an assessment with updates and recommendations about the U.S.’s current measles outbreaks, the CDC has signaled an alarming shift in its public messaging

As measles outbreaks have continued to spread in 19 U.S. states, leaders at the Centers for Disease Control and Prevention have buried a new assessment by their own experts that found there is a high risk of catching measles in areas where vaccination rates are low, according to an article published by ProPublica on March 28. The assessment had also called for a messaging strategy to encourage vaccination against the potentially deadly disease. But that plan was aborted, signaling a shift in how the agency may be responding to pressure from vaccine critic Robert F. Kennedy, Jr., who is now secretary of health and human services.
Why It Matters
Measles, caused by a highly contagious and dangerous virus, is very effectively prevented by the measles-mumps-rubella (MMR) vaccine. But rates of vaccination in the U.S. have been declining in recent years. Historically, the CDC’s messaging strategy for encouraging vaccination emphasized the importance of protecting both oneself and the community at large, especially vulnerable people who cannot yet get vaccinated such as young babies. What’s alarming about the CDC’s recent inaction is not just its decision to bury the news, health experts say, but also the agency’s justification for doing so: in a statement to ProPublica, a CDC spokesperson wrote, “The decision to vaccinate is a personal one,” a message that does not reflect long-standing scientific consensus but rather echoes the sentiment of vaccine critics such as Kennedy.

Why Vaccine Skepticism Remains a Big Problem
Vaccines, especially the MMR vaccine, have been a target of rampant misinformation in recent years. A single fraudulent study had claimed a connection between the MMR vaccine and autism, but that link was debunked years ago. Many other studies have searched for a connection and failed to find one. But lack of trust in vaccine safety remains a big public health issue: A recent survey conducted by the University of Pennsylvania found that the percentage of people who believed that already-approved vaccines were unsafe jumped from 9 percent all the way up to 16 percent between 2021 and 2023. Measles was declared eliminated from the U.S. in 2000, which means it does not circulate on its own. But outbreaks are becoming more common. The total number of people who have tested positive for measles so far this year is already higher than any full year since 2019.
What This means for the CDC and Public Health Messaging
Public health officials learned a lot from the COVID pandemic. Chief among those lessons was that frequent and transparent communication is key to establishing and maintaining trust with the public, say public health educators. Withholding essential updates and best practices undermines those goals. It can also prevent data and guidance from reaching local public health services in a timely manner.
What You Can Do to Protect Yourself
If you’re an adult who was vaccinated against MMR as a child, you can check to see if you’re still protected with a simple blood test. If you were born between 1957 and 1975, you likely only got one dose of the vaccine instead of the standard two doses that are given today. The second dose boosts the efficacy of the vaccine’s protection against measles from 93 percent to 97 percent. If you had only received one dose and live in an area where an outbreak is occurring or work in certain environments such as health care facilities, you might want to talk to your health care provider about your risk and consider an additional dose.
