New Jersey’s Rising Vaccine Exemptions: A Growing Threat to Public Health?
Vaccination rates among New Jersey children are quietly slipping, while the number of religious exemptions is climbing at an alarming rate. This trend, mirroring a national pattern, is raising concerns among public health officials who fear a resurgence of preventable diseases like measles, mumps, and rubella.
The Numbers Tell a Story
Recent data from the New Jersey Department of Health reveals a significant increase in vaccine exemptions. During the 2024-25 school year, 24,962 children were exempt from vaccinations for religious reasons – a nearly 25% jump from the previous year. While this represents only 5% of the state’s pre-K, kindergarten, first grade, sixth grade, and transfer student population, it’s almost triple the number seen a decade ago. New Jersey’s 4.6% kindergarten religious exemption rate now exceeds the national median of 4%.
The state allows exemptions for medical reasons as well, but these account for a much smaller fraction – just 0.2% of unvaccinated school children in 2024-25. The ease of obtaining a religious exemption, requiring only a signed letter from a parent or guardian without further documentation, is a key factor driving the increase.
Why the Rise in Exemptions?
The reasons behind this shift are complex. Misinformation about vaccine safety continues to circulate online and within certain communities. A growing distrust in medical institutions and government recommendations also plays a role. Some parents may also be influenced by philosophical objections or a desire for greater control over their children’s healthcare decisions.
Did you know? New Jersey is one of 29 states that permit religious exemptions to school immunization requirements. California, Connecticut, Maine, and New York are among the states that have eliminated non-medical exemptions.
The Measles Resurgence: A Warning Sign
The consequences of declining vaccination rates are already becoming apparent. The United States experienced a significant measles outbreak in 2025, with 2,255 cases reported – the highest number since 1991. A staggering 93% of these cases occurred in individuals who were unvaccinated or had an unknown vaccination status.
New Jersey has already lost its “herd immunity” to measles, meaning a sufficient percentage of the population is not immune to prevent widespread outbreaks. The CDC recommends a 95% vaccination rate for most diseases to achieve herd immunity. Currently, only 92.8% of New Jersey kindergarteners have received the MMR vaccine, down from 93% the previous year. The state reported 11 measles cases in 2025, an increase from seven the year before.
County-Level Disparities
Vaccine exemption rates aren’t uniform across New Jersey. Certain counties are experiencing significantly higher rates than others, creating localized pockets of vulnerability. (See datawrapper chart below for a county-by-county breakdown.)
What’s Next? Potential Future Trends
Several factors suggest the trend of rising vaccine exemptions could continue. Increased online activity and the spread of misinformation are likely to fuel further hesitancy. Political polarization and growing skepticism towards scientific consensus could also exacerbate the problem.
However, there are also potential counter-trends. Increased public awareness campaigns, driven by the recent measles outbreaks, could encourage more parents to vaccinate their children. Legislative efforts to tighten exemption requirements, similar to those seen in other states, could also help to boost vaccination rates.
A recent study published in the JAMA Network highlights the growing concern, linking increased non-medical exemptions to a potential resurgence of vaccine-preventable diseases.

Talk to your pediatrician about any concerns you have regarding vaccines. They are the best source of accurate and reliable information.
Frequently Asked Questions (FAQ)
Q: What is herd immunity?
A: Herd immunity occurs when a large portion of a community is immune to a disease, making the spread unlikely and protecting those who are not immune, such as infants or individuals with compromised immune systems.
Q: Can I get a vaccine exemption for philosophical reasons in New Jersey?
A: No. New Jersey law specifically states that exemptions are only permitted for medical or religious reasons. Philosophical, moral, or secular objections are not accepted.
Q: What diseases are preventable through vaccination?
A: Many serious and potentially life-threatening diseases are preventable through vaccination, including measles, mumps, rubella, polio, tetanus, diphtheria, pertussis (whooping cough), and chickenpox.
Q: Where can I find more information about vaccine safety?
A: Reliable sources of information include the Centers for Disease Control and Prevention (https://www.cdc.gov/vaccines/index.html) and the World Health Organization (https://www.who.int/vaccines).
Reader Question: “I’m worried about side effects. Are vaccines safe?” Vaccines, like all medications, can have side effects, but serious side effects are extremely rare. The benefits of vaccination far outweigh the risks. Discuss your concerns with your healthcare provider.
