Cross-Protective Immune Responses Elicited by Live Attenuated Influenza Vaccines
The desired effect of vaccination is to elicit protective immune responses against infection with pathogenic agents. An inactivated influenza vaccine is able to induce the neutralizing antibodies directed primarily against two surface antigens, hemagglutinin and neuraminidase. These two antigens undergo frequent antigenic drift and hence necessitate the annual update of a new vaccine strain. Be...
متن کاملProspects for Broadly Protective Influenza Vaccines.
The development of vaccines that could provide broad protection against antigenically variant influenza viruses has long been the ultimate prize in influenza research. Recent developments have pushed us closer to this goal, and such vaccines may now be within reach. This brief review outlines the current approaches to broadly protective vaccines, and the probable hurdles and roadblocks to achie...
متن کاملInfluenza Vaccination Strategies: Comparing Inactivated and Live Attenuated Influenza Vaccines
Influenza is a major respiratory pathogen causing annual outbreaks and occasional pandemics. Influenza vaccination is the major method of prophylaxis. Currently annual influenza vaccination is recommended for groups at high risk of complications from influenza infection such as pregnant women, young children, people with underlying disease and the elderly, along with occupational groups such a ...
متن کاملPrinciples underlying rational design of live attenuated influenza vaccines
Despite recent innovative advances in molecular virology and the developments of vaccines, influenza virus remains a serious burden for human health. Vaccination has been considered a primary countermeasure for prevention of influenza infection. Live attenuated influenza vaccines (LAIVs) are particularly attracting attention as an effective strategy due to several advantages over inactivated va...
متن کاملInfluenza viruses with rearranged genomes as live-attenuated vaccines.
H5N1 and H9N2 avian influenza virus subtypes top the World Health Organization's list for the greatest pandemic potential. Inactivated H5N1 vaccines induce limited immune responses and, in the case of live-attenuated influenza virus vaccines (LAIV), there are safety concerns regarding the possibility of reassortment between the H5 gene segment and circulating influenza viruses. In order to over...
