Vaccines are biologically derived medical preparations that provide the body with acquired immunity to specific antigens. They contain antigens (weakened or killed pathogens, their fragments, or genetic material; protein segments that trigger immunological memory). Vaccination enables a rapid and effective response to infections, eliminating cells carrying the targeted antigens.
Vaccines can induce both humoral (antibody-mediated) and cellular immune responses. Specialists design vaccine formulations based on the pathogen and its nature, selecting the appropriate vaccine type and platform. We use recombinant and vector technologies (plasmid DNA) as the most effective and safe approaches for vaccine development.
