What Role Does Cross Reactivity Play in Vaccine Development?
Cross reactivity is a double-edged sword in vaccine development. On the positive side, it can provide broad protection against multiple related pathogens. For example, a vaccine developed for one strain of influenza might offer partial protection against other strains. However, it can also lead to unintended immune responses, potentially reducing the efficacy of the vaccine or causing adverse effects. Understanding the extent and nature of cross reactivity is essential for creating effective and safe vaccines.
