South Carolina School Immunization Requirements: A Current Guide for Families

If you are preparing a child for school in South Carolina, immunization paperwork is one of the most important items to check before the first day of class. As of today, South Carolina requires a valid South Carolina Certificate of Immunization or a valid exemption for children attending childcare and school. The state's rules apply to public, private, and parochial schools, and they are designed to help reduce the spread of vaccine-preventable diseases in classrooms and childcare settings. The South Carolina Department of Public Health (DPH) also notes that children without a valid certificate or exemption will not be allowed to attend childcare or school.

Because school health rules can change from year to year, it is wise to review the current requirements before enrollment or grade promotion. For the 2026-2027 school year, South Carolina DPH published updated school guidance that includes specific changes for 6th and 12th grades. For the 2025-2026 school year, the state's official letter also highlighted changes for 5th, 7th through 12th, and 11th grades. That means families should not rely on old forms or memory alone; they should confirm the current year's requirements with the school or DPH.

Which Vaccines Are Required for School in South Carolina?

For students in grades 5K through 12, South Carolina requires documentation for several routine childhood vaccines. The core school-entry requirements include diphtheria, tetanus, and pertussis-containing vaccine; polio; measles, mumps, and rubella; hepatitis B; and varicella. In addition, students in certain grades need extra doses or boosters. The state's current guidance says that a child entering 5K through 12th grade generally needs four doses of DTP, DT, DTaP, Td, or Tdap, with at least one pertussis-containing dose on or after the fourth birthday. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2026-03/Final-School-Law-Letter-2026-2027_20260313.pdf))

South Carolina also requires a Tdap booster for students in grades 7 through 12. The dose must be given on or after the child's 10th birthday, and it may count toward the diphtheria, tetanus, and pertussis requirement. For polio, the state requires three doses, with at least one dose on or after the fourth birthday. For MMR, students need two doses, both given on or after the first birthday and separated by at least four weeks. Hepatitis B requires three doses, with the third dose given after 24 weeks of age and at least 16 weeks after the first dose. Varicella requires two doses, or a positive history of the disease.

Grade-Specific Changes Parents Should Watch

South Carolina's school immunization rules include grade-based updates that matter during transitions. For the 2025-2026 school year, the state required two doses of hepatitis A for 5th grade, one Tdap dose for grades 7 through 12, and two doses of varicella for 11th grade. For the 2026-2027 school year, the state's published update shifted the hepatitis A requirement to 6th grade and the two-dose varicella requirement to 12th grade. These changes are important because a student may be fully compliant one year and need an additional dose or updated record the next year.

Families should also note that children enrolled in 4K programs and younger must meet childcare requirements, even if the program is located in a school setting. Children in 5K through grade 12 must meet school requirements. That distinction matters for parents with children in early learning programs, since childcare rules are not identical to school rules.

What Counts as Proof of Immunization?

South Carolina uses a state immunization certificate to document compliance. The current form referenced by DPH is the SC Certificate of Immunization, and the department says doses must be valid according to accepted practice standards, including minimum ages and intervals. In practical terms, that means a vaccine dose given too early may not count, even if it appears in a child's record. Schools and childcare facilities are expected to maintain these records for enrolled children. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2025-06/Final-School-Law-Letter-2025-2026_20250646.pdf))

DPH also notes that children with a valid older DPH-2740 certificate may not need an updated DPH-4024 certificate if the older certificate was issued on or before June 30, 2022, and no further immunizations are needed through 12th grade. Families who are unsure which form they have should ask their school nurse or local health department before the enrollment deadline. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2025-06/Final-School-Law-Letter-2025-2026_20250646.pdf))

Exemptions in South Carolina

South Carolina allows exemptions, but they are limited and should be handled carefully. The state recognizes medical exemptions, religious exemptions, and a short-term special exemption. A medical exemption must be completed by a licensed physician or authorized medical representative when a child has a permanent or temporary medical reason to avoid one or more vaccines. Temporary exemptions should include an expiration date when the next immunizations are due. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2025-06/Final-School-Law-Letter-2025-2026_20250646.pdf))

A religious exemption may be granted when a parent, guardian, or person in loco parentis signs the proper section of the South Carolina Certificate of Religious Exemption stating that immunization conflicts with religious beliefs. DPH says this form can only be obtained from a DPH health department, and the parent or guardian must sign it in the presence of a notary. The state also allows a special exemption that a school may issue when a student has not yet secured immunizations or documentation; however, that exemption is only valid for 30 calendar days for the current enrollment and may be issued only once. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2025-06/Final-School-Law-Letter-2025-2026_20250646.pdf))

Why These Requirements Matter for School Health

School immunization rules are not just paperwork. They are part of a broader public health strategy to keep outbreaks from spreading quickly in classrooms, buses, cafeterias, and extracurricular activities. South Carolina DPH specifically links school vaccination requirements to the prevention of vaccine-preventable diseases. The department's measles guidance also states that current measles vaccination is required to attend childcare or school in South Carolina unless there is a valid exemption. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2026-03/Final-School-Law-Letter-2026-2027_20260313.pdf))

That same guidance notes that two doses of MMR are required for school entry from kindergarten through 12th grade, and it reports that kindergarten MMR coverage has been below the ideal level in recent years. Even when most students are vaccinated, a small number of unvaccinated children can increase the risk of outbreaks. For that reason, schools often encourage families to submit records early rather than waiting until the first week of class.

Practical Tips for Parents and Guardians

If you live in South Carolina and have a child entering school, the safest approach is to review the vaccine record several weeks before enrollment. Compare the record against the current grade-level requirements, check whether any doses were given too early to count, and confirm whether a booster is due before the new school year begins. If your child is behind on shots, the state directs families to the current ACIP catch-up schedule to determine how many doses are needed to complete the series. ([dph.sc.gov](https://dph.sc.gov/sites/scdph/files/2026-03/Final-School-Law-Letter-2026-2027_20260313.pdf))

• Check the current school year's requirements, not last year's form.
• Make sure the immunization certificate is complete and signed.
• Ask whether a dose was given at the correct age and interval.
• Confirm whether your child needs a grade-specific vaccine such as Tdap or hepatitis A.
• If you need an exemption, contact the school or a DPH health department early.

Bottom Line

South Carolina's school immunization requirements are clear, but they do change by grade and school year. For 2026, families should pay close attention to the current DPH guidance, especially for hepatitis A, Tdap, and varicella updates. The best way to avoid enrollment delays is to review records early, use the correct state form, and contact the school or DPH if anything is missing. In a state where school attendance depends on valid immunization documentation or a valid exemption, preparation is the key to a smooth start.
