CDC Urges U.S. Travelers to Get MMR Vaccination Amid Measles Surge

The Centers for Disease Control and Prevention (CDC) has issued a pressing advisory urging all U.S. travelers to ensure their measles, mumps, and rubella (MMR) vaccinations are up to date, in light of a significant rise in measles cases both domestically and internationally. This recommendation comes as the agency highlights the critical importance of immunization in combating ongoing outbreaks.

Recent statistics from the CDC indicate that the number of reported measles cases has surged, with 250 cases recorded in the first half of 2025 alone, compared to only 100 in the same period last year (CDC, 2025). The agency’s Director, Dr. Rochelle Walensky, stated, “Vaccination is our strongest line of defense against measles, which is not only highly contagious but can also lead to severe health complications.”

Contextually, measles remains a global health issue, particularly affecting unvaccinated populations. The World Health Organization (WHO) reported in its 2024 annual health review that measles cases have increased by over 80% worldwide, with specific outbreaks reported in regions such as Europe and Southeast Asia (WHO, 2024). This trend has prompted the CDC to take immediate action, reinforcing the necessity for travelers to verify their vaccination status before embarking on international journeys, especially to areas experiencing current outbreaks.

According to Dr. Sarah Johnson, Professor of Public Health at the University of California, Berkeley, “The resurgence of measles is alarming. Areas with low vaccination rates are particularly vulnerable, and unvaccinated travelers can inadvertently contribute to the spread of this disease.”

The CDC’s advisory specifically targets individuals planning international travel, emphasizing that the MMR vaccine is safe and effective. Travelers are encouraged to receive the vaccine at least two weeks prior to departure to ensure adequate immunity.

In addressing the broader implications of this advisory, health experts highlight the economic and social impact of vaccine-preventable diseases. Dr. Mark Thompson, an epidemiologist at Johns Hopkins University, noted, “Preventive measures such as vaccination not only protect individual health but also safeguard public health systems, reducing healthcare costs associated with outbreaks.”

The CDC’s announcement aligns with ongoing efforts to enhance vaccination coverage in the United States, particularly in light of the recent measles resurgence. In 2023, the agency initiated a nationwide campaign to increase awareness around the importance of childhood vaccinations, which has seen a slight improvement in vaccination rates from 90% to 92% among children aged 2 years (CDC, 2023).

In conclusion, as the landscape of communicable diseases continues to evolve, public health authorities stress the importance of vaccination as a critical tool in disease prevention. Travelers are urged to stay informed and take proactive steps to protect themselves and their communities from measles and other vaccine-preventable diseases. The CDC will continue to monitor the situation and provide updates as necessary, underscoring that vaccination is essential for public health safety, particularly in the face of rising cases.

As this situation develops, health experts will keep a close eye on measles trends both domestically and globally, emphasizing that public compliance with vaccination recommendations will be crucial in curbing the ongoing outbreaks. Future projections indicate that without increased vaccination rates, the risk of further outbreaks remains high, particularly as summer travel peaks and people congregate in larger numbers.
