Biovaccines

Biovaccines, also known as biological vaccines, are a category of vaccines derived from living organisms or their components. This broad definition encompasses a range of vaccine types, including live-attenuated vaccines, inactivated vaccines, subunit vaccines, and toxoid vaccines. Live-attenuated vaccines utilize weakened forms of a pathogen that can still replicate but are unable to cause significant disease. Inactivated vaccines use a killed version of the pathogen. Subunit vaccines employ only specific pieces of a pathogen, such as proteins or polysaccharides, to stimulate an immune response. Toxoid vaccines are made from inactivated toxins produced by certain bacteria.

The development of biovaccines relies on understanding the immunological targets of pathogens and how to safely elicit a protective immune response. They play a crucial role in preventing infectious diseases across human and animal populations. Examples include vaccines for measles, mumps, rubella, polio, and influenza. The production process for biovaccines often involves cultivating the biological material, followed by purification and formulation. Research continues to explore novel biovaccine platforms, including those utilizing viral vectors and mRNA technology, to address emerging infectious threats and improve vaccine efficacy and accessibility. Regulatory approval for biovaccines involves rigorous testing for safety and effectiveness through clinical trials.
