Vaccination Guidelines for Special Populations

Contraindications and Precautions

Patients with a history of Guillain-Barré syndrome occurring within 6 weeks after a previous tetanus toxoid-containing vaccine should avoid further tetanus toxoid if they have already received 3 or more doses, as recommended by the Centers for Disease Control and Prevention (CDC) 1
Patients with a history of Arthus-type hypersensitivity reactions should not receive tetanus toxoid more frequently than every 10 years, even for wound management, according to the CDC 1
A severe allergic reaction to a previous dose or vaccine component is a contraindication for vaccination, as stated by the CDC 2, 3
A history of encephalopathy within 7 days of previous pertussis vaccination is a contraindication for the pertussis component, and Td should be used instead of Tdap, according to the CDC 2, 3
Guillain-Barré syndrome occurring less than 6 weeks after a previous tetanus toxoid-containing vaccine is a contraindication for vaccination, as recommended by the CDC 2, 3

A progressive or unstable neurologic disorder is a precaution for pertussis components, as recommended by the CDC 2
A history of Arthus-type hypersensitivity reactions after a previous tetanus toxoid-containing vaccine is a precaution, and vaccination should be deferred for at least 10 years, according to the CDC 2, 3
Moderate or severe acute illness with or without fever is a precaution, and vaccination should be deferred until the illness is resolved, as stated by the CDC 2, 3

The CDC recommends administering Tetanus Immunoglobulin (TIG) if the tetanus vaccination is not up to date and there is a wound that is contaminated, deep, or at high risk for tetanus infection 2
For individuals with unknown or fewer than 3 doses of tetanus vaccine, TIG and tetanus toxoid-containing vaccine should be administered for all other wounds, including those contaminated with dirt, feces, soil, or saliva, puncture wounds, avulsions, and wounds resulting from missiles, crushing, burns, or frostbite, as recommended by the CDC 2
When both TIG and tetanus toxoid-containing vaccine are needed, they should be administered using separate syringes at different anatomical sites, according to the CDC 2
The recommended prophylactic dose for wounds of average severity is 250 units of TIG administered intramuscularly as a single dose, based on guidelines from the CDC 4
For individuals with 3 or more doses of tetanus vaccine, no TIG is needed for clean, minor wounds, but tetanus toxoid may be needed if it has been more than 10 years since the last dose, and for all other wounds, no TIG is needed, but tetanus toxoid may be needed if it has been more than 5 years since the last dose, as recommended by the CDC 2

The type of tetanus toxoid-containing vaccine depends on the patient's age:
Age Group Recommended Vaccine
Children <7 years DTaP
Children 7-10 years Td
Persons ≥11 years Tdap (preferred if not previously received) [2, 5]

Age Group	Recommended Vaccine
Children <7 years	DTaP
Children 7-10 years	Td
Persons ≥11 years	Tdap (preferred if not previously received) [2, 5]

Immunocompromised patients, including those with HIV, should receive TIG for contaminated wounds, regardless of their tetanus immunization history, as recommended by the CDC 2
Pregnant women should receive Tdap if tetanus prophylaxis is indicated, with one dose of Tdap during each pregnancy, preferably between 27-36 weeks, according to the CDC 2, 6

Wounds requiring consideration for TIG include contaminated wounds, puncture wounds, avulsions, and wounds from missiles, crushing, burns, and frostbite, as indicated by guidelines from the CDC 2
Cat bites are considered "dirty wounds" due to contamination with saliva and potentially soil or dirt, according to the CDC 2 and the Infectious Diseases Society of America (IDSA) 7
Immediate and thorough wound cleaning is critical for tetanus prevention, with recommended gentle irrigation with water or diluted iodopovidone solution, according to the CDC and other authorities 8, 9, 10, 5

For wounds with potential polymicrobial infection, the IDSA recommends broader coverage with antibiotics such as Piperacillin-tazobactam plus vancomycin, Imipenem-cilastatin, Meropenem, or Ertapenem, with Metronidazole as the preferred antibiotic for tetanus treatment 11
Alternative options include Penicillin G, Doxycycline, with a treatment duration of 7-10 days, as suggested by the IDSA, and the American Academy of Pediatrics and the IDSA recommending 7.5 mg/kg/dose of antibiotic every 6 hours for children with wound infections 11, 7

The case-fatality rate for tetanus remains high at approximately 25%, with higher rates in older adults, highlighting the importance of appropriate tetanus prophylaxis, according to the CDC 12
