Combination Attenuation Offers Strategy for Live Attenuated Coronavirus Vaccines

Evaluation of Live Attenuated Measles Vaccines Prepared in Human Diploid Cells for Reimmunization

Rapid Strategy for Screening by Pyrosequencing of Influenza Virus Reassortants - Candidates for Live Attenuated Vaccines

BACKGROUND Live attenuated influenza vaccine viruses (LAIVs) can be generated by classical reassortment of gene segments between a cold adapted, temperature sensitive and attenuated Master Donor Virus (MDV) and a seasonal wild-type (wt) virus. The vaccine candidates contain hemagglutinin (HA) and neuraminidase (NA) genes derived from the circulating wt viruses and the remaining six genes derive...

Envelope Exchange for the Generation of Live-Attenuated Arenavirus Vaccines

Arenaviruses such as Lassa fever virus cause significant mortality in endemic areas and represent potential bioterrorist weapons. The occurrence of arenaviral hemorrhagic fevers is largely confined to Third World countries with a limited medical infrastructure, and therefore live-attenuated vaccines have long been sought as a method of choice for prevention. Yet their rational design and engine...

Genetically modified live attenuated parasites as vaccines for leishmaniasis.

Leishmaniasis causes significant morbidity and mortality worldwide and is an important public health problem. Even though it is endemic in developing countries in tropical regions of the world,in recent years economic globalization and increased travel has extended its reach to people in developed countries. Leishmania is usually spread by the bite of the female sandfly. In addition, naïve popu...
