Molecular Basis of Live-Attenuated Influenza Virus

Molecular Basis of Live-Attenuated Influenza Virus

Human influenza is a seasonal disease associated with significant morbidity and mortality. The most effective means for controlling infection and thereby reducing morbidity and mortality is vaccination with a three inactivated influenza virus strains mixture, or by intranasal administration of a group of three different live attenuated influenza vaccine strains. Comparing to the inactivated vac...

Development of an Attenuated Live Virus Vaccine against Sheep Pox

Small-particle aerosolization of live attenuated influenza vaccine virus.

To the Editor—In their recent study, Bischoff et al [1] exposed subjects to a small-particle aerosol of commercially available live attenuated influenza vaccine (LAIV; MedImmune LLC, Gai-thersburg, MD). LAIV was used as a proxy for wild-type influenza to evaluate the protection provided by N95 respirators, surgical masks, and eye protection. Although the study addresses the important question o...

Live Attenuated Vaccines: Influenza, Rotavirus and Varicella Zoster Virus

Since vaccinia virus was first used to protect against smallpox in the eighteenth century, live attenuated vaccines have proved to be highly effective in reducing the morbidity and mortality caused by many human viral pathogens. Contemporary live viral vaccines are designed using several different strategies to achieve attenuation. These basic principles and approaches are illustrated by vaccin...

Elastase-Dependant Live Attenuated Swine Influenza Virus Vaccine in Pigs

Swine influenza (SI) is an acute, highly contagious, respiratory disease of swine caused by influenza A viruses. In addition, SI infections possess significant human public health concerns as they may serve as intermediate host for the generation of new pandemic viruses. Vaccination is still the primary method for the prevention and control of SI. Currently, commercially available vaccines agai...
