How Do Scientists Address Genetic Variability in Vaccine Design?
Scientists employ several strategies to combat genetic variability in vaccine design. One approach is the development of multivalent vaccines, which target multiple strains of a pathogen. Another strategy involves using conserved antigens, which are less likely to change across different strains. Techniques like mRNA vaccine technology, as seen with Pfizer-BioNTech and Moderna COVID-19 vaccines, allow for rapid updates to address emerging variants.
