Lf (flocculation units)
diphtheria/tetanus toxoid
injection, suspension (Td)
- (2Lf/2Lf)/0.5mL (TDVAX)
- (2Lf/5Lf)/0.5mL (Tenivac)
Primary Immunization
Adults who did not receive primary vaccination series
- Give first dose as Tdap, THEN
- Give second dose as Td 0.5 mL IM at least 4 weeks after the first dose, THEN
- Give third dose as Td 0.5 mL IM 6-12 months later
Routine Booster Immunization
0.5 mL (Td or Tdap) every 10 years (patients that have completed primary immunization)
Diphtheria Prophylaxis for Case Contacts
Indicated for postexposure prophylaxis in persons who have not completed primary vaccination, whose vaccination status is unknown, or who have not been vaccinated with diphtheria toxoid within the previous 5 yr
Administer primary series using Td to catch up with vaccinations
Tetanus Prophylaxis in Wound Management
For active tetanus immunization in wound management, a preparation containing tetanus and diphtheria toxoids (Td) is preferred instead of single-antigen tetanus toxoid to enhance diphtheria protection
The need for active immunization with a tetanus toxoid-containing preparation, with or without passive immunization with tetanus immune globulin (TIG) depends on both the condition of the wound and the patient’s vaccination history
Clean minor wounds
- Unknown or <3 tetanus doses: Administer Td
- 3 or more tetanus doses (if <10 years since last dose): No dose needed
- 3 or more tetanus doses (>10 years since last dose): Administer Td
All other wounds
- Unknown or <3 tetanus doses: Administer Td and TIG
- 3 or more tetanus doses (if <5 yr since last dose): No dose needed
- 3 or more tetanus doses (>5 yr since last dose): Administer Td; if patient has history of Arhus-type reaction, administer only if at least 10 yr since last tetanus-containing immunization

Warnings
Contraindications
Hypersensitivity to toxoids or any component of the formulation
Cautions
Prior to the administration of the vaccine recipient’s current health status and health history should be reviewed; this includes a review of the immunization history of the patient, the presence of any contraindications to immunization, and any adverse events after previous immunizations to allow an assessment of the benefits and risks of vaccination
Treatment (including epinephrine 1:1000) for anaphylactoid/hypersensitivity reactions should be immediately available when administering vaccine
Check vaccine for latex content
Do not exceed dosing frequency; more frequent doses may be associated with increased incidence and severity of adverse reactions
Persons who experienced an Arthus-type hypersensitivity reaction following a prior dose of a tetanus toxoid-containing vaccine usually have high serum tetanus antitoxin levels and should not receive tetanus-containing vaccines more frequently than every 10 years, even for tetanus prophylaxis as part of wound management
Evidence supports a causal relation between tetanus toxoid and both brachial neuritis and Guillain-Barré syndrome; if Guillain-Barré syndrome occurred within 6 weeks of receipt of prior vaccine containing tetanus toxoid, the decision to give any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks
Vaccination may not protect all individuals
Administration to immunocompromised individuals may not obtain expected immune response
Prior to administration of the vaccine, patients, parents, or guardians should be informed by the health care provider of the benefits and risks of immunization and of the importance of completing the primary immunization series or receiving recommended booster doses
Drug interaction overview
- Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids (used in greater than physiologic doses), may reduce the immune response
Pregnancy & Lactation
Pregnancy
There are insufficient human data from Td administered during pregnancy to establish the presence or absence of a vaccine-associated risk
ACIP guidelines include immunizing pregnant women during every pregnancy with 1 dose of Tdap to convey immunity for pertussis to fetus during gestational weeks 27-36
Animal studies
- Female rabbits received a single human dose (0.5 mL) of Td IM 17 and 10 days before mating, and on gestation days 6 and 29; no adverse effects on preweaning development up to postnatal day 35 were observed
- There were no vaccine-related fetal malformations or variations observed
Lactation
Unknown if excreted in human milk
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Tetanus: Tetanus is an acute disease caused by an extremely potent neurotoxin produced by C tetani; protection against disease is imparted by the development of neutralizing antibodies to tetanus toxin; serum tetanus antitoxin level of at least 0.01 IU/mL, measured by neutralization assay is considered the minimum protective level
Diphtheria: Diphtheria is an acute toxin-mediated disease caused by toxigenic strains of C diphtheriae; protection against disease is imparted by the development of neutralizing antibodies to diphtheria toxin; serum diphtheria antitoxin level of 0.01 IU/mL is the lowest level giving some degree of protection; antitoxin levels of at least 0.1 IU/mL are generally regarded as protective
Administration
IM Preparation
Just before use, shake the single-dose vial or syringe well until a uniform, white, cloudy suspension results
Inspected visually for particulate matter and discoloration; if these conditions exist, do not administer.
Do not combine through reconstitution or mix with any other vaccine
IM Administration
For IM administration only; do not administer IV, SC, or intradermally
Adults and children aged 7 years or older
- Administer IM in the deltoid muscle (preferred site)
- Do not inject into the gluteal area or areas where there may be a major nerve trunk
Children aged younger than 7 years
- Infants aged <1 year: Inject IM in anterolateral aspect of the thigh provides the largest muscle and is the preferred site of injection
- Older children: Administer IM in the deltoid muscle is usually large enough for injection; do not inject into the gluteal area or areas where there may be a major nerve trunk
Storage
Refrigerate at 2-8ºC (36-46ºF)
Do not freeze; discard if exposed to freezing
