Last year, the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) reported a concerning 20% rise in global measles cases, totaling an estimated 10.3 million. This alarming figure resulted in approximately 107,500 fatalities, predominantly among young children, from a disease that is entirely preventable through vaccination. The organizations labeled this death toll as "unacceptable," emphasizing the critical role of vaccination in preventing measles, a disease that can be both deadly and debilitating. The highly effective measles vaccine offers 93% protection with a single dose and 97% protection with two doses.

The resurgence in measles cases is attributed to a decline in vaccination rates. Despite being eradicated in 82 countries over the past five decades, the world has seen a reversal due to limited access to vaccines and the spread of misinformation regarding their safety. The Covid-19 pandemic has further exacerbated this issue, leading to a decrease in the number of individuals receiving standard vaccinations. Measles is so contagious that herd immunity requires a 95% vaccination rate to protect those who cannot be vaccinated, including infants too young for the vaccine.

Globally, in 2023, only 83% of children received their first dose of the measles vaccine, and a mere 74% received the recommended second dose, according to health organizations. Over 22 million children missed out on vaccination entirely. In the United States, a drop in measles vaccination rates among kindergartners has kept coverage below the federal target for four consecutive years. The CDC data from October showed that the vaccination rate for kindergartners in the 2023-24 school year was 92.7%. As of November 7, 2024, the CDC reported 266 measles cases in the US, with 16 outbreaks.

The gaps in global vaccine coverage have led to a 60% increase in significant measles outbreaks in 2023, with 57 countries experiencing large or disruptive outbreaks, up from 36 in 2022. Measles outbreaks have impacted nearly every region, with nearly half occurring in Africa. In 2023, there was an 8% decrease in measles-related deaths compared to the previous year. This reduction is not due to the virus being less lethal but rather because outbreaks were in areas where children had better access to healthcare and proper nutrition. Children with weakened immune systems due to malnutrition or other underlying diseases are more susceptible to death from measles.

Up to three out of every 1,000 children infected with measles may die from respiratory and neurologic complications, according to the CDC. While general symptoms include fever, cough, runny nose, watery eyes, and a rash of red spots, measles can also result in lifelong health issues, particularly for infants and children. It can cause blindness, brain damage, and pneumonia, with about 1 in 20 children with measles developing pneumonia.

"The measles vaccine has saved more lives than any other vaccine over the past 50 years," stated WHO Director-General Dr. Tedros Adhanom Ghebreyesus. "To save even more lives and prevent this deadly virus from harming the most vulnerable, we must invest in immunization for every individual, regardless of their location." CDC Director Dr. Mandy Cohen emphasized the importance of not regressing in vaccination efforts, reminding us of the devastating effects of diseases like polio and measles. "We have a short memory of what it's like to hold a child paralyzed by polio or to comfort a mother who has lost her child to measles," Cohen said at the Milken Institute’s Future of Health Summit. "We need to remember that the reason we have these childhood vaccines is to ensure that we are the strongest, healthiest community possible."

The decline in measles vaccination rates is a global concern that requires immediate attention. It is not only a matter of individual health but also a collective responsibility to maintain the progress made in disease eradication. The consequences of not vaccinating are far-reaching, affecting not just the health of individuals but also the stability of healthcare systems and the overall well-being of communities.

Vaccination is a proven and effective tool in preventing the spread of measles and other vaccine-preventable diseases. It is a matter of public health and safety, and it is crucial that we continue to prioritize vaccination programs worldwide. The decline in vaccination rates must be addressed through education, increased access to vaccines, and by combating misinformation that undermines the importance of vaccination.

Global health organizations, governments, and communities must work together to ensure that every child has access to life-saving vaccines. This includes addressing the barriers to vaccination, such as cost, accessibility, and logistical challenges, as well as fostering trust in the safety and efficacy of vaccines.

The measles vaccine is a testament to the power of medical science in saving lives and preventing suffering. It is our collective duty to ensure that this life-saving tool reaches every individual who needs it, regardless of where they live. By doing so, we can protect future generations from the devastating effects of measles and other vaccine-preventable diseases.

The current situation serves as a stark reminder of the importance of maintaining high vaccination rates and the consequences of allowing these rates to fall. It is a call to action for all stakeholders to redouble their efforts in promoting and ensuring vaccination, not just for measles but for all vaccine-preventable diseases. The health and well-being of our global community depend on it.
