Viral Antigens Market Size, Share, and Industry Analysis By Component (Influenza, HIV, Hepatitis, Ebola, and Others), By Product Type (Native Antigens and Recombinant Antigens), By Application (Vaccine Development, Therapeutics, Diagnostics, Research & Development, and Others), By End User (Diagnostic Laboratories, Hospitals and Clinics, Pharmaceutical & Biotechnology Companies, and Research and Academic Institutes), and Regional Forecast till 2032

The global viral antigens market is expanding with an escalation in the prevalence of various viral infections such as hepatitis, HIV, and influenza, among others. The growing endeavor of several public and private players to bolster the development of antiviral drugs and vaccines has led to an increase in collaborations between them and is anticipated to drive the antigen demand over the ensuing years.

Viral antigens are gaining traction in the healthcare industry as they create an immune response in the host and are given off by a virus. They can be used for a range of applications including the treatment of tumors, vaccine development, and the diagnosis of viral infections.

• According to the National Center for Biotechnology Information (NCBI), 64.44% virus-specific B cell epitopes are situated in viral antigens that remain enclosed within viral particles or host cells.

Viral Antigens Market Driver

Supportive Government Policies and Increase in R&D Initiatives

The governments of several countries are investing in various public health initiatives and programs focused on disease prevention. For instance, the COVID-19 pandemic period recorded a range of vaccine development and immunization initiatives for curbing the spread of the virus. Besides, governments were also keen to make arrangements for the treatment of the infection, which escalated the demand for antigens.

Furthermore, an increase in research and development initiatives is elevating the demand for viral antigens across various countries. Several studies are being conducted by regulatory bodies and research institutes for analyzing antigenic variants.

• According to NCBI (National Center for Biotechnology Information), a study focused on the analysis of antigenic similarity among influenza A (H3N2) viruses recorded the development of an interpretable machine learning model for analyzing antigenic variants.

Viral Antigens Market Restraint

Stringent Regulatory Framework May Slow Down the Process of Development and Distribution

The strict regulatory policies associated with the development, production, and distribution of viral antigens may lead to a delay in the launch of new products. Another potential hindrance for the market is the lack of standardization of viral antigens. This could result in inconsistencies in diagnostic results and research findings.

Viral Antigens Market Opportunity

Soaring Advancements in Recombinant DNA Technologies

The increasing advancements in recombinant DNA technologies and the benefits of scalable and cost-effective production is likely to create new growth opportunities over the coming years. Furthermore, the escalated significance of targeted therapeutics and personalized medicine is expected to boost the demand for highly-specific antigens.

Analysis by Component

Based on component, the viral antigens market is categorized into influenza, HIV, hepatitis, Ebola, and others.

The influenza segment is poised to record a dominant share in the global market. This is mainly due to the growing incidence of various types of influenza across several countries. Industry players are introducing a range of antigen products to curb the growing prevalence and help the prevention of viral outbreaks. To cite an instance, according to NCBI, SARS-CoV-2’s spike (S) protein is more likely to induce neutralizing antibody production, reflecting immune status.

The hepatitis segment is depicting considerable growth, driven by the rising emphasis on measurement of antigen levels for determining the presence of the virus. For instance, the HBsAg (Hepatitis B surface antigen) levels are assessed for diagnosing the presence of the hepatitis B virus. In addition, there is a rising demand for the development of vaccines for the prevention of the infection.

Analysis by Product Type

By product type, the viral antigens market is divided into native antigens and recombinant antigens.

The recombinant antigens segment dominates the global market. As these antigens are produced through genetic engineering, they are highly scalable, stable, and have a longer shelf life. These antigens also record a high demand as they are more uniform and their development involves less time and cost.

Comparatively, native antigens exhibit limited scalability and their consistency varies with source material. Furthermore, these antigens have a shorter shelf life on account of sensitivity to environmental conditions such as pH and temperature. Impelled by these factors, the native antigens segment is anticipated to grow at a significant rate over the coming years.

Analysis by Application

On the basis of application, the market is subdivided into vaccine development, therapeutics, diagnostics, research & development, and others.

The diagnostics segment is depicting significant growth owing to an increase in technological advancements. The demand for viral antigens is rising in this segment driven by progress in diagnostic technologies such as ELISA (enzyme-linked immunosorbent assay) and PCR (polymerase chain reaction). The antigens are useful in the quantification and detection of viral infections.

The vaccine development segment is anticipated to record substantial expansion over the forthcoming years. This is due to an increase in the launch of vaccine development programs and favorable policies by the governments of several countries. For instance, the COVID-19 pandemic period registered a heightened emphasis on bringing effective vaccines to the market.

Analysis by End User

Based on end user, the market is divided into diagnostic laboratories, hospitals and clinics, pharmaceutical & biotechnology companies, and research and academic institutes.

An increase in the demand for viral antigens for the diagnosis of viral infections drives the significant expansion of the diagnostic laboratories segment. For instance, according to NCBI (National Center for Biotechnology Information), in a study involving the comparison of recombinant versus natural antigens in SARS-CoV-2 serology, ELISA using rNP (recombinant nucleocapsid protein) depicted a sensitivity of 83.61% and specificity of 92.00%.

The research and academic institutes segment is poised to exhibit considerable growth owing to a surge in research and development activities across the globe. These initiatives are aimed at developing new vaccines for a range of viral infections. An increase in R&D investments by the governments of various countries is another factor influencing product demand in these settings.

Regional Analysis

By geography, the viral antigens market has been studied across North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa.

North America depicts the presence of a robust research and development infrastructure and is a leader in the development of new vaccines and diagnostic solutions. In addition, the region records substantial government investments for research in the field of infectious diseases by regulatory bodies such as the Centers for Disease Control and Prevention and the National Institutes of Health. These factors drive the dominance of the region in the global market.

Europe records considerable investments in virology research and the presence of well-established healthcare systems. The regional market is anticipated to hold the second largest share with an increase in coordinated efforts of the European Union in the surveillance and control of infectious diseases.

Asia Pacific depicts rising investments in pharmaceutical and biotechnology research and rapid expansion of the healthcare industry. The heightened emphasis on the improvement of public health system and healthcare infrastructure further drives industry expansion. The prominent players in the Asia Pacific vaccine research and production industry are India and China.
