Vaccination Recommendations for Post-Myelitis Travel

Critical Safety Principle

• The Centers for Disease Control and Prevention recommends that patients with a history of myelitis and positive oligoclonal bands should avoid live vaccines due to the risk of triggering relapse or worsening neurological symptoms 1
• Live vaccines are absolutely contraindicated in patients with immune-mediated neurological conditions like myelitis, as stated by the Clinical Infectious Diseases journal 1

Timing Considerations

• The American College of Physicians recommends waiting at least 4-6 weeks before travel to allow adequate time for vaccination and immune response development, as suggested by Praxis Medical Insights 2
• The Centers for Disease Control and Prevention advises starting the vaccination process immediately, as insufficient lead time is the most common vaccination error, according to Praxis Medical Insights 2

Safe Inactivated Vaccines by Destination

• The Centers for Disease Control and Prevention recommends ensuring routine inactivated vaccines are current, including Tetanus-Diphtheria-Pertussis (Tdap), which should be updated if more than 10 years have passed since the last dose, as stated in MMWR Recommendations and Reports 3, 4
• The World Health Organization suggests using only inactivated form of Inactivated Poliovirus Vaccine (IPV), never oral live vaccine, as recommended by MMWR Recommendations and Reports 5, 6
• The Centers for Disease Control and Prevention recommends annual inactivated influenza vaccine, especially important given a neurological history, as stated in MMWR Recommendations and Reports 3, 4
• The American Academy of Neurology advises against receiving the Measles-Mumps-Rubella (MMR) vaccine, as it is a live vaccine and contraindicated in patients with a history of myelitis, according to Clinical Infectious Diseases 1

Destination-Specific Inactivated Vaccines

• The Centers for Disease Control and Prevention recommends Meningococcal ACWY conjugate vaccine for travel to Sub-Saharan Africa, with boosters every 5 years if continued risk, as stated in MMWR Recommendations and Reports 7, 2
• The World Health Organization suggests Meningococcal ACWY vaccine is mandatory for entry into Saudi Arabia, as recommended by MMWR Recommendations and Reports 7, 2
• The Centers for Disease Control and Prevention advises considering Hepatitis A, Typhoid, and Hepatitis B vaccines for travel to developing countries or endemic areas, as suggested by Praxis Medical Insights 2, 8
• The American Society of Tropical Medicine and Hygiene recommends Japanese Encephalitis vaccine if spending more than 1 month in endemic areas during transmission season, according to Praxis Medical Insights 2

Vaccines to Absolutely Avoid

• The Clinical Infectious Diseases journal recommends never receiving live vaccines, including Yellow Fever, Oral Polio Vaccine (OPV), Oral Typhoid vaccine (Ty21a), MMR, Varicella, and any other live-attenuated vaccine, due to the risk of triggering relapse or worsening neurological symptoms 1, 5, 6, 8

Implementation Strategy

• The American Academy of Neurology advises consulting a neurologist immediately to document contraindication to live vaccines and obtain medical waiver letters, as suggested by Praxis Medical Insights 8
• The Centers for Disease Control and Prevention recommends scheduling vaccination appointments 4-6 weeks before departure, as stated by Praxis Medical Insights 2
• The World Health Organization suggests bringing documentation, including vaccination records and medical waiver letters, for border crossings, as recommended by Praxis Medical Insights 8
