When we think of measles, most of us immediately consider its well-known complications: high fever, pneumonia, encephalitis, and even death. This understanding drives many parents to vaccinate their children, not just to protect them, but also to shield their communities from the virus. However, some still underestimate the serious nature of measles and opt out of vaccinations due to unfounded fears surrounding the shots. This lack of vaccination has led to alarming outbreaks across the nation, with experts attributing the rise in cases to unvaccinated individuals.
It’s crucial to recognize that measles is not merely an inconvenience like a common cold or a rash. The Centers for Disease Control and Prevention (CDC) reports that prior to the widespread introduction of the measles vaccine in the U.S., around 48,000 people were hospitalized annually due to measles complications, with approximately 500 deaths occurring each year due to the virus.
Recent research has uncovered an alarming aspect of measles: it can lead to what doctors are terming “immune system amnesia.” According to two significant studies—one featured in the journal Science and another in Science Immunology—measles doesn’t just make you sick; it can also drastically weaken your immune system’s ability to fend off other viruses in the future.
This phenomenon occurs as the virus can erase the immunity built up against other diseases, such as the flu or pneumonia. Researchers warn that these immune-damaging effects can persist for years, which is particularly concerning for parents of young children. Kids are more susceptible to illnesses like measles due to their developing immune systems, and they often catch various bugs during their early years.
My own experience with young kids taught me that they frequently fall ill, but I found some comfort in knowing that these exposures were helping to strengthen their immune systems. However, contracting measles could drastically change that narrative. Thankfully, my children received their measles vaccinations on time, and according to the CDC, two doses of the vaccine are 97% effective in preventing the disease.
It’s hard to fathom why some parents would choose to forgo this critical protection for their children. The consequences of measles are severe and can lead to long-lasting immune system damage, which could put children at risk for various other serious illnesses. Dr. Samuel Hartman, a lead researcher in one of the studies, emphasized in an interview with the New York Times that by refusing the measles vaccine, parents are not only risking their child’s health but also compromising their previously acquired defenses.
The study involved 77 unvaccinated children during a measles outbreak in the Netherlands in 2013. Researchers collected blood samples from these kids before and after they contracted measles, using a specialized tool called VirScan to measure antibody levels. They found that those who contracted measles experienced a staggering 11-73% reduction in antibodies, with an average loss of around 40%.
In another study, the team discovered that measles eradicated immune memory B cells in these children, effectively reverting their immune systems to a less mature state. This indicates that measles is far more dangerous than previously understood and can have long-lasting effects on our immune capabilities, even after the virus has cleared. As Velislava Petrova, a lead author of the Science Immunology study, succinctly put it, getting vaccinated is essential not just to prevent measles but also to avoid other secondary infections that can arise due to compromised immunity.
As a parent, the risk of my child contracting a virus that could lead to severe illness, potentially death, and long-term immune damage is simply not worth it. Measles poses a threat that is even more significant than we realized. The good news is that vaccination remains one of the most effective ways to protect your children, yourself, and everyone around you from its devastating consequences. So please, prioritize vaccination for your family. There’s no valid reason to take that risk.

In summary, measles is a serious illness that poses significant risks not only for immediate health but also for long-term immune function. Vaccination is crucial to protect children and the wider community from the dangers associated with this virus.
