The rising prevalence of bacterial infections is expected to drive the growth of the diphtheria market in the coming years. Bacterial infections occur when bacteria invade the body, causing illness either through direct infection or by producing toxins. Diphtheria, a serious bacterial infection, is caused by strains of Corynebacterium diphtheriae, which weaken the immune system and promote bacterial growth. For example, in September 2024, according to GOV.UK, a UK government website, NHS acute trusts in England reported 38,757 cases of E. coli bacteremia during the fiscal year 2022-2023, with 7,881 (20.3%) of these cases being hospital-onset infections. As bacterial infections continue to rise, the diphtheria market is expected to grow accordingly.

The diphtheria market is experiencing growth, largely underpinned by the upward trajectory of immunization programs. Immunization programs encompass a suite of services aimed at safeguarding individuals against vaccine-preventable illnesses by delivering vaccinations. These programs are designed to curtail sickness, disability, and mortality stemming from vaccine-preventable maladies. Diphtheria and other vaccines are routinely administered to individuals through immunization initiatives spanning different countries and regions. For instance, in July 2023, the United Nations International Children's Emergency Fund (UNICEF) reported an uptick in global coverage for the third dose of the Diphtheria, Tetanus, Pertussis (DTP3) vaccination. This coverage increased from 81% in 2021 to 84% in 2022 through immunization efforts. Consequently, the escalating prominence of immunization programs is a propellant behind the growth of the diphtheria market.

Companies engaged in the diphtheria market are actively innovating and securing FDA approvals to maintain their market positions. A prime example of such innovation occurred in October 2022 when GlaxoSmithKline PLC, a U.K.-based pharmaceutical and biotechnology firm, announced that the U.S. Food and Drug Administration (FDA) granted approval for BOOSTRIX (Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, adsorbed; Tdap). This approval permits immunization during the third trimester of pregnancy to prevent pertussis (whooping cough) in infants under two months old. Administering the Tdap vaccine to pregnant women confers optimal protection against whooping cough for newborns during their initial months of life through the transference of protective antibodies from mother to child.
