The Hidden World of Vaccine Exemption Services Explored
A new kind of marketplace has emerged around vaccine exemptions, and it’s raising some eyebrows. Frontline Health Advocates is offering medical exemption notes for a fee. But what exactly are they selling? And how legal or ethical is it?
Many parents find out about these services through social media, online forums, or targeted ads. Cassandra Clerkin, a mother from upstate New York, contacted Frontline early in the 2024–2025 school year. Her child had seizures after a vaccine, and she didn’t want her kids to get more shots. New York’s rules on school vaccines are strict, so she thought maybe a medical exemption could help.
How Frontline Claims to Help Parents
Frontline Health Advocates appears to be a company that sells medical exemption letters to parents who want to avoid vaccinating their children. They advertise on various platforms, including Facebook, Reddit, and Rumble. Their website, which was registered in March 2022, offers quick access to exemption documents. The process seems straightforward: parents pay around $495, speak with a representative, and then receive a medical exemption letter via email.
In Clerkin’s case, she spoke with someone from Frontline who made the process sound easy. After paying, her family got a letter signed by a doctor named Andrew Zywiec. The letter claimed her child’s vaccination restrictions were permanent, citing health concerns, and warned of penalties if ignored. Clerkin submitted this letter to the school district, which accepted it.
The Legal and Ethical Questions
While some parents report success with these exemption letters, questions swirl about legality. Many states have strict rules about who can write medical exemptions. In some places, only licensed physicians can attest to a child’s medical need for an exemption. Frontline’s doctors include chiropractors and other providers who may not be authorized to issue such certificates.
Experts warn that these exemption letters might not hold up in court. They’re often based on broad or vague health claims, and some legal professionals believe the strategy could be risky. There’s concern that parents are confused about what they’re actually receiving—are these legitimate medical documents or something less?
States like California and New York have cracked down on improper exemptions. California, after a measles outbreak in 2015, saw a spike in medical exemptions. Critics say some doctors were issuing exemptions without proper medical justification, creating a black market. New York eliminated religious exemptions in 2019 and has increased oversight, banning certain providers from accessing immunization records.
The People Behind the Service
William Lionberger, a chiropractor with a license dating back to 1981, is listed as the founder of Frontline. He has also worked as a police officer and has been associated with groups opposed to COVID-19 vaccines. The organization’s website was registered in 2022, and it markets itself as a way to obtain exemptions quickly and easily.
Critics see Frontline as part of a broader trend—an organized effort to provide shortcuts around vaccine laws. Its legal approach includes forming as a Private Ministerial Association, a tactic some groups use to claim exemption from certain regulations. However, legal experts question whether these strategies will stand up in court.
While Frontline advertises a team of “medical experts,” the legitimacy of their medical evaluations remains uncertain. They claim to work with various conditions and claim to evaluate each case individually. But without transparency about their medical staff or detailed credentials, many wonder how genuine these assessments are.
In the end, the rise of such services highlights ongoing tensions around vaccine laws, parental rights, and medical ethics. While some parents see them as a lifeline, others worry about the potential for abuse or legal trouble. As these services grow, so does the debate about what’s fair and legal in the complex world of vaccination requirements.
