Prophylactic approach to delay viral infections Several host pathogen interactions have been mapped with respect to white spot syndrome virus (WSSV) infection. The interaction of any virus with its host's cellular receptors initiates a chain of dynamic events that enable entry of the virus into the host cell. The capability of viral attachment proteins (VAP) to bind to these specific cellular receptors is the basis of cell and tissue tropism and eventual infection. Researchers have reported that intramuscular injection of antiserum against WSSV major envelope protein VP28 was able to neutralize WSSV infection of L. vannamei in a concentration-dependent manner.

VP37, VP39 and a couple of over 97 KDa proteins have been identified as VAPs which would interact with a range of host proteins. Karyovir™ is capable of disrupting some of these critical host protein interactions and thereby preventing a possible entry of viral particles into the host.
