Subunit Vaccines Market Analysis, Size, Growth, Trends and Forecast to 2021

The global Subunit Vaccines market is classified on the basis of type, product type, indications, application and geography. A vaccine is a biological preparation that delivers active acquired immunity to a specific disease. A vaccine usually contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body’s immune system to identify the agent as a threat, destroy it, and keep a record of it so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

There are different types of vaccines such as inactivated, toxoid, attenuated, subunit, conjugate, and so on. Subunit vaccines are vaccines that use only part of the disease-causing virus.Subunit vaccines, like inactivated whole-cell vaccines, do not contain live components of the pathogen. They differ from inactivated whole-cell vaccines, by containing only the antigenic parts of the pathogen. These parts are necessary to elicit a protective immune response.

The factors that propel the global growth include long-lived immunity provided by this vaccine and risk of reactions are very low. In addition, subunit vaccines can be given to people with weakened immune systems. On the other hand, there are also factors that hamper the growth of the market such as numerous doses are required for proper life-long immunity.

On the basis of type, the market research report is classified as protein-based subunit vaccines, polysaccharide vaccine and conjugate subunit vaccine. Protein based subunit vaccines present an antigen to the immune system without viral particles, using a specific, isolated protein of the pathogen. Commonly used protein-based subunit vaccines are acellular pertussis (aP) vaccines and Hepatitis B.

Some bacteria when infecting humans are often protected by a polysaccharide (sugar) capsule that helps the organism evade the human defence systems especially in infants and young children. Polysaccharide vaccines create a response against the molecules in the pathogen’s capsule. These molecules are small, and often not very immunogenic.Examples of polysaccharide vaccines include Meningococcal disease caused by Neisseria meningitidis groups A, C, W135 and Y, as well as Pneumococcal disease.

Conjugate subunit vaccines also create a response against the molecules in the pathogen’s capsule. In comparison to plain polysaccharide vaccines, they benefit from a technology that binds the polysaccharide to a carrier protein Carrier protein A, a protein linked to a weak antigen to increase its immunogenicity when used as a vaccine that can induce a long-term protective response even in infants.

Various protein carriers are used for conjugation, including diphtheria and tetanus toxoid. Conjugate subunit vaccines, can therefore prevent common bacterial infections for which plain polysaccharide vaccines are either ineffective in those most at risk or provide only short-term protection.

On the basis of product type, the Subunit Vaccines market is classified as Pneumococcal, Influenza, HPV, Hepatitis, Rotavirus, DTP, Polio and MMR. On the basis of indications, the Subunit Vaccines market is classified as infectious disease, cancer and allergies. On the basis of application, the Subunit Vaccines market is classified as paediatric and adult.

On the basis of geography, the Subunit Vaccines market is classified as North America, Europe, Asia Pacific and Rest of World. The key players mentioned in the market research report includes Astellas Pharma Inc., CSL Limited, Emergent BioSolutions, Inc., GlaxoSmithKline, Johnson & Johnson, MedImmune, LLC, Merck & Co, Pfizer, Sanofi Pasteur and Serum Institute India Pvt. Ltd.
