How Do Host-Virus Interactions Influence Vaccine Efficacy?
Host-virus interactions can affect vaccine efficacy in several ways:
1. Immune Response: A robust initial immune response to a viral infection can enhance vaccine efficacy by providing a strong memory response. 2. Genetic Variability: Genetic differences among individuals can influence how well they respond to a vaccine. 3. Pre-existing Immunity: Prior exposure to a virus or similar viruses can affect the immune response to a vaccine, either enhancing or diminishing its efficacy.
