Not Vaccinating Your Kids Endangers Public Health
A pediatrician gives a one-year-old child a vaccine.
[Editor's Note: This opinion essay is in response to our current Big Question, which we posed to experts with different viewpoints: "Where should society draw the line between requiring vaccinations for children and allowing parental freedom of choice?"]
Society has a right and at times an obligation to require children to be vaccinated. Vaccines are one of the most effective medical and public health interventions. They save lives and prevent suffering. The vast majority of parents in the United States fully vaccinate their children according to the recommended immunization schedule. These parents are making decisions so that the interests of their children and the interest of society are the same. There are no ethical tensions.
"Measles is only a plane ride away from American children."
A strong scientific basis supports the recommended immunization schedule. The benefits of recommended vaccines are much bigger than the risks. However, a very small proportion of parents are ideologically opposed to vaccines. A slightly larger minority of parents do not believe that all of the recommended vaccines are in their child's best interests.
Forgoing vaccinations creates risk to the child of contracting diseases. It also creates risk to communities and vulnerable groups of people who cannot be vaccinated because of their age or health status.
For example, many vaccines are not able to be given to newborns, such as the measles vaccine which is recommended at 12-15 months of age, leaving young children vulnerable. Many diseases are particularly dangerous for young children. There are also some children who can't be vaccinated, such as pediatric cancer patients who are undergoing chemotherapy or radiation treatment. These children are at increased risk of serous complication or death.
Then there are people who are vaccinated but remain susceptible to disease because no vaccine is 100% effective. In the case of measles, two doses of vaccines protect 97% of people, leaving 3% still susceptible even after being fully vaccinated. All of these groups of people – too young, not eligible, and vaccinated but still susceptible – are dependent on almost everyone else to get vaccinated in order for them to be protected.
Sadly, even though measles has been largely controlled because most people get the very safe and very effective vaccine, we are now seeing dangerous new outbreaks because some parents are refusing vaccines for their children, especially in Europe. Children have died. Measles is only a plane ride away from American children.
There have been repeated measles outbreaks in the United States – such as the Disneyland outbreak and six outbreaks already this year - because of communities where too many parents refuse the vaccine and measles is brought over, often from Europe.
The public health benefits cannot be emphasized enough: Vaccines are not just about protecting your child. Vaccines protect other children and the entire community. Vaccine-preventable diseases (with the exception of tetanus) are spread from person to person. The decision of a parent to not vaccinate their child can endanger other children and vulnerable people.
As a vaccine safety researcher for 20 years, I believe that the community benefit of vaccination can provide justification to limit parental autonomy.
Given these tensions between parental autonomy and the protective value of vaccines, the fundamental question remains: Should society require all children to submit to vaccinations? As a vaccine safety researcher for 20 years, I believe that the community benefit of vaccination can provide justification to limit parental autonomy.
In the United States, we see this balancing act though state requirements for vaccinations to enter school and the varying availability of non-medical exemptions to these laws. Mandatory vaccination in the United States are all state laws. All states require children entering school to receive vaccines and permit medical exemptions. There are a lot of differences between states regarding which vaccines are required, target populations (daycare, school entry, middle school, college), and existence and types of non-medical (religious or philosophical) exemptions that are permitted.
Amid recent measles outbreaks, for instance, California eliminated all non-medical exemptions, making it one of three states that only permit medical exemptions. The existence and enforcement of these school laws reflect broad public support for vaccines to protect the community from disease outbreaks.
I worry about how many kids must suffer, and even die, from diseases like measles until enough is enough. Such tragedies have no place in the modern era. All parents want to do right by their children. All parents deserve autonomy when it comes to decision-making. But when their choices confer serious risks to others, the buck should stop. Our nation would be better off—both medically and ethically—if we did not turn our backs on our most vulnerable individuals.

Here's how one doctor overcame extraordinary odds to help create the birth control pill
Dr. Percy Julian had so many personal and professional obstacles throughout his life, it’s amazing he was able to accomplish anything at all. But this hidden figure not only overcame these incredible obstacles, he also laid the foundation for the creation of the birth control pill.
Julian’s first obstacle was growing up in the Jim Crow-era south in the early part of the twentieth century, where racial segregation kept many African-Americans out of schools, libraries, parks, restaurants, and more. Despite limited opportunities and education, Julian was accepted to DePauw University in Indiana, where he majored in chemistry. But in college, Julian encountered another obstacle: he wasn’t allowed to stay in DePauw’s student housing because of segregation. Julian found lodging in an off-campus boarding house that refused to serve him meals. To pay for his room, board, and food, Julian waited tables and fired furnaces while he studied chemistry full-time. Incredibly, he graduated in 1920 as valedictorian of his class.
After graduation, Julian landed a fellowship at Harvard University to study chemistry—but here, Julian ran into yet another obstacle. Harvard thought that white students would resent being taught by Julian, an African-American man, so they withdrew his teaching assistantship. Julian instead decided to complete his PhD at the University of Vienna in Austria. When he did, he became one of the first African Americans to ever receive a PhD in chemistry.
Julian received offers for professorships, fellowships, and jobs throughout the 1930s, due to his impressive qualifications—but these offers were almost always revoked when schools or potential employers found out Julian was black. In one instance, Julian was offered a job at the Institute of Paper Chemistory in Appleton, Wisconsin—but Appleton, like many cities in the United States at the time, was known as a “sundown town,” which meant that black people weren’t allowed to be there after dark. As a result, Julian lost the job.
During this time, Julian became an expert at synthesis, which is the process of turning one substance into another through a series of planned chemical reactions. Julian synthesized a plant compound called physostigmine, which would later become a treatment for an eye disease called glaucoma.
In 1936, Julian was finally able to land—and keep—a job at Glidden, and there he found a way to extract soybean protein. This was used to produce a fire-retardant foam used in fire extinguishers to smother oil and gasoline fires aboard ships and aircraft carriers, and it ended up saving the lives of thousands of soldiers during World War II.
At Glidden, Julian found a way to synthesize human sex hormones such as progesterone, estrogen, and testosterone, from plants. This was a hugely profitable discovery for his company—but it also meant that clinicians now had huge quantities of these hormones, making hormone therapy cheaper and easier to come by. His work also laid the foundation for the creation of hormonal birth control: Without the ability to synthesize these hormones, hormonal birth control would not exist.
Julian left Glidden in the 1950s and formed his own company, called Julian Laboratories, outside of Chicago, where he manufactured steroids and conducted his own research. The company turned profitable within a year, but even so Julian’s obstacles weren’t over. In 1950 and 1951, Julian’s home was firebombed and attacked with dynamite, with his family inside. Julian often had to sit out on the front porch of his home with a shotgun to protect his family from violence.
But despite years of racism and violence, Julian’s story has a happy ending. Julian’s family was eventually welcomed into the neighborhood and protected from future attacks (Julian’s daughter lives there to this day). Julian then became one of the country’s first black millionaires when he sold his company in the 1960s.
When Julian passed away at the age of 76, he had more than 130 chemical patents to his name and left behind a body of work that benefits people to this day.
