Legal framework, state-by-state status, and recent developments
State vaccine exemption laws vary across the United States. While all states require certain vaccinations for school entry, most also provide exemptions for individuals with sincerely held religious beliefs. As of April 2026, 44 states and the District of Columbia permit religious exemptions from school vaccination requirements, according to the National Conference of State Legislatures (NCSL). Six states do not: California, Connecticut, Maine, Mississippi, New York, and West Virginia.
The legal framework governing religious exemptions comes from both constitutional law and state legislation. Courts have generally upheld school vaccination laws, including laws that do not provide a religious exemption. At the same time, debates continue over religious liberty, parental autonomy, public health policy, and how much documentation states may require.
West Virginia's status is currently the subject of active litigation before the state's Supreme Court. In January 2025, Governor Patrick Morrisey issued Executive Order 7-25, directing state officials to create a religious exemption process based on the state's Equal Protection for Religion Act (EPRA). The West Virginia Board of Education has contested this interpretation, and the case (Guzman v. West Virginia Board of Education, WV Supreme Court Case No. 25-740) is pending a ruling. This page reflects the legal landscape as of April 2026; readers should verify current status for any state before making decisions.
The legal balance between religious liberty and public health mandates is shaped primarily by the First Amendment's Free Exercise Clause and by how federal courts have interpreted it.
Two early Supreme Court decisions established the legal foundation for state vaccination authority:
Jacobson v. Massachusetts, 197 U.S. 11 (1905): The Supreme Court held that a state may enforce compulsory vaccination laws under its police power (its authority to protect health and safety). The Court ruled that individual liberty is not absolute and may be restricted when the common welfare requires it.
Zucht v. King, 260 U.S. 174 (1922): The Supreme Court upheld a city ordinance requiring vaccination as a condition of school attendance, confirming that such requirements do not violate the Fourteenth Amendment's Equal Protection or Due Process Clauses.
Employment Division v. Smith, 494 U.S. 872 (1990): The Supreme Court held that a neutral, generally applicable law (one that applies across the board rather than targeting religion) does not violate the Free Exercise Clause, even if it has an incidental effect on religious practice. Under this standard, a vaccination law that applies equally to everyone regardless of religious belief is generally upheld without requiring the government to demonstrate a compelling interest.
Fulton v. City of Philadelphia, 593 U.S. 522 (2021): The Supreme Court held that when a government system allows individualized exceptions (such as discretionary secular exemptions), heightened judicial scrutiny may apply (meaning the government may face a more demanding legal test) to the denial of religious exemptions. This ruling involved foster care agency contracting, not vaccine mandates. Courts have not yet applied Fulton directly to vaccine exemption cases, but legal scholars have noted its potential relevance to states that grant secular but not religious exemptions.
Workman v. Mingo County Board of Education, 419 F. App'x 348 (4th Cir. 2011): The Fourth Circuit unanimously upheld West Virginia's school vaccination requirement, which provided no religious exemption, concluding that it did not violate the Free Exercise Clause. The court stated that even under strict scrutiny (the most demanding form of constitutional review), the state's interest in preventing communicable disease justified the requirement. The Supreme Court declined to hear the appeal (Case No. 11-380, cert. denied November 2011).
Phillips v. City of New York (2nd Cir. 2015): The Second Circuit cited Workman in holding that mandatory vaccination as a condition of school attendance does not violate the Free Exercise Clause. The court relied on the reasoning of Jacobson, Prince v. Massachusetts, and Workman in rejecting the plaintiffs' constitutional challenge.
Six states do not permit religious exemptions from childhood vaccination requirements. These states reached that result through three different legal paths: legislative repeal, judicial invalidation, and non-enactment. The following table summarizes each state's history, with primary statutory and case law citations.
| State | Elimination Mechanism | Citation |
|---|---|---|
| California | Legislative repeal (2015). Eliminated personal belief exemption, including religious beliefs. | SB 277; Cal. Health & Safety Code Section 120335 |
| Connecticut | Legislative repeal (2021). Eliminated religious exemption effective April 28, 2021. | PA 21-6 (sHB 6423) |
| Maine | Legislative repeal (2019; effective September 1, 2021). Eliminated both religious and personal belief exemptions. | HP 586; Me. Rev. Stat. tit. 20-A, Section 6355 |
| Mississippi | Judicial invalidation (1979); court-ordered reinstatement (2023). The state Supreme Court struck down the religious exemption on equal protection grounds in Brown v. Stone (1979). In April 2023, a federal court ordered the Mississippi State Department of Health to create a religious exemption process in Bosarge v. Edney (S.D. Miss.). The exemption is now operational through MSDH procedures but has not been codified in statute. | Brown v. Stone, 378 So.2d 218 (Miss. 1979); Bosarge v. Edney, 669 F.Supp.3d 598 (S.D. Miss. 2023) |
| New York | Legislative repeal (2019). | A02371 |
| West Virginia | Never enacted by legislature. Status in active litigation: Governor's Executive Order 7-25 (Jan 2025) claims EPRA creates religious exemption; circuit court injunction issued Nov 2025; stayed by WV Supreme Court Dec 2025. Appeal pending (briefing through June 2026). | W. Va. Code Section 16-3-4; W. Va. Code Section 35-1A-1 (EPRA); Guzman v. WVBE, WV Sup. Ct. Case No. 25-740 |
Brown v. Stone, 378 So.2d 218 (Miss. 1979), is the only instance in which a state's religious exemption was eliminated through judicial action rather than legislation.
Facts: A Mississippi father challenged the state's vaccination exemption statute, which granted exemptions only to members of religious groups whose tenets conflicted with vaccination. The father's denomination was not among the groups recognized by the state.
Holding: The Mississippi Supreme Court struck down the religious exemption entirely, ruling that granting exemptions only to certain religious sects violated the Equal Protection Clause of the Fourteenth Amendment (the constitutional guarantee that similarly situated people must be treated equally under the law).
Reasoning: The court held that the religious exemption discriminated against children whose parents did not belong to qualifying religious groups. The court stated that the protection of school children from communicable diseases constituted a "compelling public purpose" that prevailed over the religious exemption. (Brown v. Stone, 378 So.2d 218, at 223.)
Significance: Mississippi remains one of only two states (along with West Virginia, pending resolution of its current litigation) that have never had a legislatively enacted religious exemption available. Mississippi's exemption was judicially invalidated rather than legislatively repealed, making it a distinct case in the national landscape.
West Virginia's exemption status is the subject of the most significant active litigation in vaccine exemption law as of April 2026. In practical terms, the dispute is whether West Virginia's existing law still allows only medical exemptions or whether newer state religious-liberty law requires officials to recognize a religious exemption process. The following timeline is based on court filings, executive orders, and official agency statements:
| Date | Development |
|---|---|
| May 2023 | WV Legislature enacts the Equal Protection for Religion Act (EPRA), W. Va. Code Section 35-1A-1, prohibiting state actions that substantially burden religious exercise unless essential to a compelling governmental interest. |
| Jan 14, 2025 | Governor Patrick Morrisey issues Executive Order 7-25, directing state officials to create a religious exemption process for school vaccination requirements, citing EPRA. |
| May 2025 | Governor issues additional guidance to parents on how to obtain religious exemptions. |
| June 2025 | WV Board of Education votes unanimously to instruct county school boards to reject religious exemptions, maintaining that W. Va. Code Section 16-3-4 provides only for medical exemptions. |
| Aug 12, 2025 | Raleigh County Circuit Judge Michael Froble grants preliminary injunction in Guzman v. WVBE (No. CC-41-2025-C-240), requiring schools to accept religious exemptions. |
| Aug 21, 2025 | HHS OCR sends letter to WV health departments asserting that EPRA requires recognition of religious exemptions as a condition of Vaccines for Children Program (VCP) participation. |
| Nov 26, 2025 | Judge Froble issues permanent injunction and declaratory relief, certifying a statewide class action. 659 religious exemptions processed for 2025-2026 school year. |
| Dec 2, 2025 | WV Supreme Court stays Froble's ruling (Case No. 25-740). Board of Education reinstates guidance rejecting religious exemptions. |
| Mar 2026 | Board of Education files appeal brief with WV Supreme Court. Plaintiffs' response due May 11, 2026; reply brief due June 1, 2026. |
The 2025 and 2026 WV legislative sessions both considered bills to codify religious and philosophical vaccination exemptions in state law. Neither session enacted such legislation.
Note: This section will be updated as the WV Supreme Court proceedings develop.
On September 4, 2025, the U.S. Department of Health and Human Services' Office for Civil Rights (OCR) issued a nationwide letter to all state Vaccines for Children Program (VCP) awardees. The letter stated that VCP-participating immunization programs and program-registered providers must respect state religious and conscience exemptions from vaccine mandates, according to the HHS press release.
HHS Secretary Robert F. Kennedy, Jr. stated that the letter was intended to make clear that "providers must respect state laws protecting religious and conscience-based exemptions to vaccine mandates," and described the letter as part of a broader effort to strengthen enforcement of laws protecting conscience and religious exercise, according to the same press release.
The letter followed an earlier letter specific to West Virginia (August 21, 2025) and applies to all states participating in the VCP. The nationwide letter is available at hhs.gov/sites/default/files/ocr-nationwide-vaccine-letter.pdf.
Note: This reflects a federal policy position. Its legal authority and enforceability remain subjects of active debate among legal scholars, state officials, and federal agencies.
Four of the six states that eliminated religious exemptions included specific transitional provisions for students who had previously claimed exemptions. These provisions, sometimes called grandfathering rules (transitional rules allowing some previously approved exemptions to continue), are documented in OLR Report 2021-R-0196 (Connecticut General Assembly, Office of Legislative Research, October 28, 2021).
Children who filed personal belief exemptions before January 1, 2016, could continue to claim the exemption until they reached their next "grade span." California defines three grade spans: birth to preschool, kindergarten through 6th grade, and 7th through 12th grade (Cal. Health & Safety Code Section 120335(g)). Additionally, if the state adds new vaccinations to the required list, students must be allowed to claim a personal belief exemption from those specific new vaccines (Section 120338). The law specifies that it does not prohibit students with Individualized Education Programs (IEPs) from accessing special education services (Section 120335(h)).
Students enrolled in grades kindergarten through 12th grade who submitted a religious exemption prior to April 28, 2021, were grandfathered and may retain their exemption, including if they transfer to another public or private school in the state. Students enrolled in pre-kindergarten or other preschool programs were required to comply with immunization requirements by September 1, 2022, or within 14 days after transferring to a different program, whichever was later. The law allows these children to extend the compliance timeframe if a physician, physician assistant, or advanced practice registered nurse recommends an alternative immunization schedule.
Maine's law grandfathered students with Individualized Education Programs (IEPs) who claimed an exemption by September 1, 2021. For these students, a parent, guardian, or the student (if age 18 or older) must provide a statement from a physician, nurse practitioner, or physician assistant confirming that the provider has consulted with the family about the risks and benefits of immunization (Me. Rev. Stat. tit. 20-A, Section 6355). Maine's IEP-specific carve-out is a distinctive feature not shared by the other states that eliminated religious exemptions.
New York's law did not include a broad grandfathering clause. For the 2019-2020 school year only, the law allowed school entry for students who had not completed all required immunizations if, within specified time frames, they demonstrated that they had received their first dose of each required vaccine and had age-appropriate appointments scheduled to receive the remainder.
Mississippi and West Virginia did not include transition provisions. Mississippi's exemption was judicially invalidated in 1979, and West Virginia has never legislatively enacted a religious exemption (its current status is the subject of pending litigation as described above).
States that permit religious exemptions may assess whether a claimed religious belief is sincerely held, while generally avoiding judgments about whether the belief is theologically correct. Courts and state agencies use sincerity testing to distinguish genuinely religious objections from philosophical, medical, or political objections framed in religious terms.
The Supreme Court has established several principles relevant to sincerity assessments:
United States v. Seeger, 380 U.S. 163 (1965): The Court defined religious belief broadly, encompassing any sincere and meaningful belief that occupies a place in the life of its possessor parallel to that filled by an orthodox belief in God. The belief need not be part of an organized religion.
Welsh v. United States, 398 U.S. 333 (1970): The Court extended protections to deeply held moral and ethical beliefs that function as religion in the individual's life, even if the individual does not characterize them as religious.
Thomas v. Review Board, 450 U.S. 707 (1981): The Court held that courts may assess the sincerity of a religious belief but may not evaluate its theological correctness or reasonableness. A claimant's belief need not be shared by all members of their religious sect to qualify for protection.
Requirements for demonstrating sincerity vary by state. Some states accept a signed parental statement without further inquiry. Others require notarized affidavits, educational consultations, or review by state health officials. A small number of states have implemented more rigorous review processes in response to concerns about exemption misuse, though the specific procedures and standards differ by jurisdiction.
