The Role of Vaccine Exemptions in the Outbreak of Diseases
It is evidenced that there exists a clear link between vaccine exemptions and outbreaks of diseases. Studies have shown that as nonmedical exemption rates are higher, so are the rates of outbreaks higher in terms of frequency and severity for such diseases as measles and pertussis. These outbreaks are not just about a failure of individual responsibility but a systemic issue exacerbated by permissive exemption policies.
For example, the Disneyland measles outbreak in 2015 reflected the risks of having numerous nonmedical exemptions. The outbreak flowed into many states, infecting hundreds of people from the unvaccinated individual. It took very little time for the diseases to spread in communities where exemption rates were very high because the herd immunity had been tampered with.
Another such case is pertussis, where the consequences of vaccine exemption are deadly. Even with overall high vaccination coverage in states with high exemption rates, pertussis outbreaks have occurred, particularly among school-aged children. The combination of waning immunity from the pertussis vaccine and the clustering of unvaccinated individuals has created pockets of vulnerability where the disease can take hold.
These outbreaks have important implications for public health in terms of morbidity and mortality rates but also in their economic costs of control. Substantial resources, therefore, go into quarantine measures, vaccination campaigns, and public health investigations during outbreaks. The indirect costs involve lost productivity and long-term health consequences that burden society as a whole.
The Legal and Ethical Case for Restricting Vaccine Exemptions
These risks justify a number of legal and ethical restrictions on vaccine exemptions, particularly the nonmedical exemptions, to public health. The state has a legally compelling interest in protecting public health, which may justify limitations on individual freedoms. This was upheld by several court cases where courts ruled that the interest of the state in preventing disease outweighed the individual claims of religious or philosophical exemptions.
This can also be viewed, from an ethical perspective, as an extension of the principle of justice that no person, or group of persons, bears a disproportionate share of the burden of vaccine-preventable diseases. It also falls squarely in line with the principle of nonmaleficence in that it prevents harm to others, especially those most vulnerable.
But it’s also painstakingly hard to restrict vaccine exemptions. One major worry is that such efforts may, in fact, fuel further resistance and more deeply entrenched vaccine hesitancy. Hence, public health officials must strike a balance between stringent vaccination requirements and measures meant to build trust with the public and educate them on the benefits of vaccines.
Conclusion
The debate about vaccine exemptions in the United States is quite literally at a crossroads. More and more vaccine-preventable diseases appear as a threat, largely in communities with higher exemption rates. At the same time, ethical and legal justifications for limiting these exemptions grow stronger. The challenge is to devise policies that meet all requirements in terms of protecting public health, respecting individual freedoms, and also addressing concerns underlying vaccine hesitancy.
This means that in the future, tightened exemption laws, public education, and addressing the root causes of vaccine hesitancy are further measures to be implemented by policymakers. The United States will ensure that the obtained milestones in controlling vaccine-preventable diseases are not reversed through a preventable resurgence.
