Mechanism of action

Ervebo is a live attenuated VSV vector vaccine expressing the Ebola virus glycoprotein, which primes the immune system. The booster dose is administered to enhance and prolong protective immunity after an initial Ervebo vaccination series. This heterologous prime-boost strategy leverages the VSV platform to generate robust cellular and humoral immune responses against Ebola.
