Influenza A (H5N1) viruses are strong candidates for causing the next influenza pandemic if they acquire the ability for efficient human-to-human transmission. A major public health goal is to make efficacious vaccines against these viruses by using novel approaches, including cell-culture system, reverse genetics, and adjuvant development. Important consideration for the strategy includes prep...
• For almost 60 years, the WHO Global Influenza Surveillance and Response System (GISRS) has been the key player in monitoring the evolution and spread of influenza viruses and recommending the strains to be used in human influenza vaccines. The GISRS has also worked to continually monitor and assess the risk posed by potential pandemic viruses and to guide appropriate public health responses. ...
Seasonal influenza vaccines are unique because they are regularly reformulated and prepared in anticipation of the upcoming influenza season. Selection of vaccine strains occurs in advance of the influenza season, allowing time for vaccine production. Influenza viruses constantly evolve, and mismatches between vaccine strains and circulating strains have occurred in the past, impacting on vacci...
In the fall of 2004, the United States faced a national shortage of influenza vaccine after a major vaccine manufacturer was unable to produce millions of doses of the vaccine due to potential contamination. Many public and private sector entities had far fewer doses of influenza vaccine to allocate than they had anticipated. In response, federal, state, and local public health officials, priva...
Respiratory viruses infections caused by influenza viruses, human parainfluenza virus (hPIV), respiratory syncytial virus (RSV) and coronaviruses are an eminent threat for public health. Currently, there are no licensed vaccines available for hPIV, RSV and coronaviruses, and the available seasonal influenza vaccines have considerable limitations. With regard to pandemic preparedness, it is impo...
T he United States has recently experienced influenza vaccine shortages because of manufacturing problems and distribution delays. During the 2004-2005 season, only 61 of the expected 100 million influenza vaccine doses were available to the US market after 1 of the 2 licensed companies withdrew their product. The Centers for Disease Control and Prevention (CDC) recommended that available vacci...
The influenza virus is a serious threat to public health worldwide. A novel avian influenza A (H7N9) virus with a mortality rate of approximately 30% has been identified as an unusually dangerous virus for humans by the World Health Organization. Pathogenic H7N9 continue to represent a public health concern, and several candidate vaccines are currently in development. We generated candidate H7N...
A twenty-first century novel influenza A (H1N1) pandemic is currently unfolding, and the eventual scope of this public health crisis is not clear. In addition, ongoing surveillance of the avian influenza A (H5N1) virus reveals outbreaks of human-to-human transmission of the virus, with significant mortality. Effective pandemic management depends on pharmaceutical intervention with two different...
The seasonal influenza vaccine is currently the most effective preventive modality against influenza infection. Nasopharyngeal samples of vaccinated and non-vaccinated patients presenting with Influenza-like-illness (ILI) were collected from over 20 outpatient clinics located in different geographic parts of Israel and were tested for the presence of influenza viruses (influenza A and influenza...
Background and Purpose: Pregnant women are at a higher risk of influenza infection, and influenza vaccination is recommended for these women to reduce the associated complications. This study aimed to determine the knowledge and practice about influenza vaccination and identify the factors influencing compliance with influenza immunization among pregnant women. Methods: This cross-sectional ...
