Resurgence of Measles, Pertussis Fueled by Vaccine Refusals

I was born in 1950 and was home-schooled until the 6th grade. Thus, I missed exposure to several childhood illnesses that affected most of my generation. I never gave it much thought until, as a medical resident in North Carolina in 1979, I came down with a potentially life-threatening febrile illness that required hospitalization. Only after four days of 105 degree fever did a rash appear, and the diagnosis was made: measles. That was the sickest I have ever been. It turned out that one of my daughter’s school friends had developed measles in a small outbreak of unvaccinated kids in Chapel Hill, and I had been exposed to her. I was born too early to have been vaccinated.

But for most people born in the United States after the 1960s, they have never had to experience the high fever and rash of the measles or the coughing fits of pertussis, commonly known as whooping cough. That’s because these extremely contagious and potentially life-threatening diseases have been controlled with the use of highly effective vaccines and strong vaccination programs. And yet, the number of Americans sickened with measles and pertussis each year has recently crept back up.

Now, an NIH-funded report confirms that many of the recent outbreaks of these vaccine-preventable diseases have been fueled by refusal by some parents to have their children vaccinated [1]. The findings, published recently in JAMA, come as an important reminder that successful eradication of infectious diseases depends not only on the availability of safe and effective vaccines, but also on effective communication about the vaccines and the diseases they prevent.

No Link Between MMR Vaccine and Autism, Even in High-Risk Kids

Study after study has found no link between autism spectrum disorders (ASD) and the measles-mumps-rubella (MMR) vaccine—or any vaccine for that matter. Yet many parents still refuse or delay vaccinations for their young children based on misplaced fear of ASD, which can be traced back to a small 1998 study that’s since been debunked and retracted [1]. Such decisions can have a major negative impact on public health. With vaccination rates in decline, we’ve recently seen the resurgence of measles and other potentially fatal childhood infectious diseases.

Among the parents most likely to avoid getting their kids vaccinated are those who already have a child with ASD. So, it’s especially important and timely news that researchers have once again found no link between MMR vaccines and ASD—even among children known to be at greater risk for autism because an older sibling has the developmental brain disorder.
