Measles is highly contagious, with one infected individual capable of transmitting the virus to up to 90% of unvaccinated people exposed to it, as noted by the George Washington University’s online MPH program. However, the measles vaccine, typically administered as part of the MMR (measles, mumps, and rubella) shot, boasts a 97% efficacy rate with two doses. While the vaccine was licensed in 1963, outbreaks were significantly curtailed by the 1980s, yet it wasn’t deemed eliminated until 2000.
How Did We Regress from Elimination to Outbreaks?
The answer lies primarily with the anti-vaccination movement.
It’s essential to differentiate between immunization and vaccination. Immunization occurs when we develop resistance to a disease, whether through infection or vaccination. A vaccine, on the other hand, consists of a weakened or inactive form of the virus or bacteria it aims to prevent. This process prompts our bodies to produce antibodies necessary to combat the disease. Therefore, when we encounter the actual virus, our immune systems are equipped to defend us.
Critics of vaccines often point fingers at pharmaceutical companies or government entities, labeling vaccines as unsafe. However, the vaccine development process is meticulous and comprehensive. Dr. Sarah Johnson of the FDA stated, “The overwhelming scientific evidence confirms that vaccines are among the safest and most effective measures to prevent illness and protect public health. Vaccinating against measles, mumps, and rubella safeguards not just ourselves and our children but also those who cannot be vaccinated, such as immunocompromised individuals.”
The Vaccine Development Process
The vaccine development process involves several rigorous steps. Initially, scientists isolate natural or synthetic proteins that may prevent or treat a disease. These antigens must then be tested for efficacy and safety. Many candidates do not progress beyond this stage due to ineffectiveness or harmful effects. If successful, the vaccine moves to clinical trials, which consist of three distinct phases of human testing. Should it pass all evaluations, the company seeks FDA approval before it can be manufactured and distributed.
Even following approval, manufacturers must adhere to strict quality control standards to ensure ongoing vaccine safety and effectiveness. The Vaccine Adverse Event Reporting System and the Vaccine Safety Datalink are vital resources for monitoring the performance of vaccines. It’s worth emphasizing that serious vaccine-related injuries are exceedingly rare.
Despite claims from the anti-vaccination movement, vaccines are largely safe and effective. The World Health Organization (WHO) indicates that most vaccine reactions are minor and temporary, such as a sore arm or mild fever. In fact, the risk of injury from a vaccine-preventable illness is significantly higher than from the vaccine itself.
The Role of Misinformation
The rise of the internet has facilitated the spread of misinformation regarding vaccines, exacerbating the anti-vaccination sentiment. Recent outbreaks of measles have occurred in states like Washington and Minnesota, where parents can cite personal or philosophical exemptions to opt out of vaccinations. Emma Turner, a health advocate, noted that recent outbreaks in South Carolina were concentrated in communities that resisted vaccinations on religious grounds.
As the anti-vaccination rhetoric gains traction, the incidence of diseases like measles—once thought to be eradicated—rises. Parents often express various concerns about vaccines, including fears of multiple shots too soon, the presence of “chemicals,” and misconceptions about how these substances work. These worries can lead to the rejection of vaccination, undermining the hard work that has gone into developing these life-saving interventions.
Measles is no longer a relic of the past in the United States; it has returned, and it is imperative to vaccinate our children to curb this trend.

Summary
Vaccination is a crucial public health measure that prevents diseases like measles. Despite fears and misinformation propagated by the anti-vaccination movement, extensive research and regulatory processes confirm the safety and efficacy of vaccines. Ensuring widespread vaccination is vital for individual and community health.
