What Are The Market Size Estimates For The Oral Vaccine Market?

The oral vaccine market has experienced rapid expansion recently. This market is projected to expand from $3.59 billion in 2024 to $3.95 billion in 2025, demonstrating a compound annual growth rate (CAGR) of 10.1%. Historically, this growth was driven by greater investments in vaccine research and development, supportive regulatory environments for oral vaccine trials, an increase in global travel and tourism, the necessity for widespread immunization during outbreaks, and improved cold chain infrastructure.

The oral vaccine market is anticipated to experience robust expansion over the coming years. This market is projected to reach $5.74 billion by 2029, expanding at a compound annual growth rate (CAGR) of 9.8%. This projected growth during the forecast period can be attributed to factors such as the increasing worldwide prevalence of infectious diseases, a growing preference for needle-free vaccine methods, better acceptance among young patients, enhanced patient adherence, and the expansion of governmental immunization initiatives. Key trends expected during this period involve the introduction of novel oral vaccine technologies, continuous progress in oral drug delivery systems, increased partnerships between public and private entities, the creation of oral vaccines targeting non-conventional ailments, and advancements in encapsulation and formulation methods.

What Drivers Are Accelerating Expansion Of The Oral Vaccine Market?

The increasing occurrence of infectious diseases is anticipated to boost the expansion of the oral vaccine market going forward. These illnesses arise from detrimental microorganisms such as bacteria, viruses, fungi, or parasites, capable of transmission among individuals or via the environment. The surge in infectious diseases is linked to greater global mobility, which enables the swift transfer of people and disease-causing agents across national borders, thereby hastening the global dissemination of infections. Oral vaccines prove advantageous against infectious diseases as they activate mucosal immunity within the gut, a critical entry point for numerous pathogens, thus providing robust defense where infections originate. For instance, in May 2025, according to the Health Security Agency, a UK-based government department, in England, the count of reported tuberculosis (TB) cases in 2023 showed an 11.0% rise compared to 2022. Consequently, the growing incidence of infectious diseases is fueling the expansion of the oral vaccine market.

Which Disruptive Trends Are Driving Change Across The Oral Vaccine Market?

Key companies in the oral vaccine market are concentrating on creating advanced products, like second-generation oral pill vaccines, aimed at boosting immune responses and simplifying their delivery. Such a second-generation oral vaccine, administered in pill form, aims to enhance immunogenicity, expand protective coverage, and facilitate mass immunization, eliminating the need for injections or specific temperature control. For example, in March 2025, Vaxart Inc., a U.S.-based biotechnology company, disclosed the start of a Phase 1 clinical trial for its second-generation oral norovirus vaccine, presented in a pill formulation. This trial will assess the improved immune responses and safety profiles of the updated constructs, with the goal of meeting the continuous global demand for readily available and efficacious norovirus immunization. The pill format overcomes obstacles linked to injectable vaccines and enables swift, widespread distribution, especially critical during outbreaks.
