Humanized vaccines are a vital part of modern medicine as they create a more natural immune response in individuals than regular vaccines. Humanized vaccines are innovative and technologically advanced creations that use molecular biology techniques to produce virus-like particle (VLP) vaccines, subunit vaccines, and nucleic acid-based vaccines that imitate the pathogen's structure. The term "humanized vaccine" is often used interchangeably with the words "recombinant vaccine," "biotech vaccine," "targeted vaccine," and "precision vaccine." These terms are used to describe vaccines that are designed to be more specific to the individual's antigenic makeup and to produce a more potent immune response. Humanized vaccines are providing better protection against emerging diseases like COVID-19, influenza, and other pathogens.
