Boostrix® Vaccine Description 2023
Boostrix® is a U.S. Food and Drug Administration (FDA)-approved vaccine for preventing tetanus, diphtheria, and pertussis (Tdap) in people at least ten years old. Approved in 2005, Boostrix is also available for adults who need a booster. Boostrix contains inactive substances produced by the bacteria that cause tetanus and diphtheria. Boostrix also includes fragments of the bacteria that cause pertussis (whooping cough).
Since 2012, the U.S. Centers for Disease Control and Prevention (CDC) has recommended using Tdap vaccines during the third trimester of each pregnancy. And on October 7, 2022, the U.S. Food and Drug Administration (FDA) announced the approval to use Boostrix (STN: BL 125106) during the third trimester of pregnancy specifically to prevent pertussis in infants younger than two months. When the Boostrix vaccine is given during pregnancy, it boosts antibodies in the mother, which are transferred to the developing baby.
The FDA granted these approvals to GlaxoSmithKline Biologicals.
The U.S. FDA approved Boostrix in 2005 as a single dose for booster immunization against tetanus, diphtheria, and pertussis in individuals. The FDA gas licensed 12 combination vaccines to help protect against diphtheria and tetanus. Nine of these vaccines also help protect against whooping cough.
Boostrix Vaccine Dosage
Boostrix is administered as a single 0.5-mL intramuscular injection into the upper arm muscle and is approved for use as a single dose in individuals ten and older. Boostrix is generally given whenever a booster dose of diphtheria and tetanus vaccine is required and where a booster for pertussis is desired. It may also be given in the case of a tetanus-prone injury where a booster for diphtheria and pertussis is also required, provided no previous dose of tetanus vaccine was given within five years previously.

Boostrix Vaccine Clinical Trials
A clinical trial, Immunogenicity & Reactogenicity of Boostrix 10 Years After Previous Booster Vaccination in Study NCT01267058, assessed the efficacy and safety of repeating Tdap booster in adults ten years after previous booster vaccination with Tdap in an earlier clinical study. Before the decennial booster, 89.4% and 94.8% of subjects were seroprotected (antibodies ≥0.1 IU/mL) for diphtheria and tetanus, respectively. One-month post-booster, all subjects were seroprotected/seropositive against all vaccine antigens.
GSK's Boostrix vaccine has been involved in over 140 clinical trials.
