Vaccination Guidelines for Patients with Seizure History

Introduction to Vaccination Precautions

Patients with a history of seizures should receive separate MMR and varicella vaccines instead of the combination MMRV vaccine, as recommended by the Centers for Disease Control and Prevention (CDC) 1
A personal history of seizures is considered a precaution for MMRV vaccine use, not a contraindication, according to the CDC 1

The Advisory Committee on Immunization Practices (ACIP) supports simultaneous administration of all indicated vaccines, including the acellular pertussis vaccine (in Tdap), which has a lower risk of inducing fever compared to whole-cell pertussis vaccines 2
For patients with a history of seizures, acellular pertussis vaccine (Tdap) is the vaccine of choice, and patients with stable neurologic conditions, including well-controlled seizures, may be safely vaccinated with Tdap, as recommended by the ACIP 2
The American Academy of Pediatrics (AAP) and the ACIP support the simultaneous administration of COVID-19 vaccines with other vaccines, including MMR, based on extensive experience with non-COVID-19 vaccines showing similar immunogenicity and adverse event profiles when administered simultaneously compared to alone 3
Multiple vaccines (e.g., MMR, Shingrix, influenza, and typhoid) can be safely administered during the same visit at different anatomical sites, with no need to delay any of these vaccinations, increasing the probability of full immunization, as recommended by the CDC 4

Consider prophylactic antipyretics, such as acetaminophen or ibuprofen, to reduce the possibility of post-vaccination fever in patients with a history of seizures, as recommended by the ACIP 2
Ensure the patient's seizure condition is stable and well-controlled before vaccination, and consider delaying vaccination until the condition stabilizes if necessary, according to the ACIP 2
A personal or family history (sibling or parent) of seizures is a precaution for MMRV vaccine use, and children with seizure history should generally receive separate MMR and varicella vaccines instead of MMRV, as recommended by the CDC 1

If the patient's neurologic condition is not stable or seizures are not well-controlled, consider delaying vaccination until the condition stabilizes, as recommended by the ACIP 2
Patients with stable neurologic conditions, including well-controlled seizures, may be safely vaccinated with Tdap, according to the ACIP 2
The AAP and ACIP recommend that COVID-19 vaccines can be administered concomitantly with other vaccines, including MMR, with the benefits of timely vaccination outweighing the risk of potential reactogenicity 3

Live vaccines, such as MMR, should be separated from other live vaccines by at least 4 weeks to prevent potential interference with immune response, but inactivated vaccines, including most COVID-19 vaccines, can be administered at any time before or after live vaccines like MMR, as recommended by the ACIP 5
Inactivated vaccines can be administered simultaneously with any other inactivated or live vaccines, according to the CDC 4, 6
Each vaccine must be administered at a different injection site, using separate syringes, and not mixing vaccines in the same syringe unless FDA-approved, as stated by the CDC 4
Combination vaccines (e.g., MMR, DTaP) are preferred over separate injections of equivalent component vaccines, according to the CDC 4

The American Academy of Pediatrics recommends a vaccination schedule for children, consisting of two doses of MMR vaccine: the first dose at 12-15 months of age and the second dose at 4-6 years of age, with a minimum age for the first dose of 12 months, as recommended by the American Academy of Pediatrics and the CDC 7, 1
If not previously vaccinated, 2 doses of MMR can be administered during any visit with at least 4 weeks between doses, as recommended by the American Academy of Pediatrics 7
Children who have not received the second dose by age 11-12 years should complete the schedule at that time, as recommended by the American Academy of Family Physicians 8

Antibody-containing products should be administered at least 2 weeks before or several months after receiving live vaccines to avoid interference with immune response, as recommended by the CDC 9
The CDC recommends clearly documenting each vaccine administered, including manufacturer, lot number, site, and date of administration, and providing vaccine information statements for each vaccine, as recommended by the CDC 4, 1

When administering multiple vaccines simultaneously, there may be increased reactogenicity (local and systemic reactions), including injection site reactions, systemic symptoms, and rare febrile seizures, with the American Academy of Pediatrics (AAP) noting that common side effects include pain, redness, swelling, fever, and fatigue 3
Common side effects include injection site reactions (pain, redness, swelling) and mild systemic symptoms (fever, fatigue), which may be accentuated when vaccines with local or systemic reactions are administered simultaneously, and monitoring for fever, local reactions, and allergic reactions is recommended 10
Parents should be counseled about the possibility of fever, mild rash, rare possibility of febrile seizures, and local injection site reactions after MMR vaccination, as recommended by the Centers for Disease Control and Prevention (CDC) 11, 1
