Pharmacokinetics
How It Works
This vaccine contains inactivated Japanese Encephalitis virus protein, which stimulates the immune system to produce specific antibodies against the virus. Upon administration, the inactivated viral proteins are recognized as foreign by the immune system, leading to the activation of B-cells and T-cells. This results in the production of neutralizing antibodies that provide protection against future infection with the Japanese Encephalitis virus.
