Introduction The influenza virus is an RNA virus has an envelope that included members of the family Orthomyxoviridae. Its genome is a single negative strand segmented RNA. This virus consists of three types: A, B, and C. Influenza types A and B has eight segments of RNA, but the influenza virus type C only has 7 segments (Cheung and Poon, 2007). Influenza A virus is a virus that spread and infect many species of animals such as pigs, horses, cats, tigers, leopards, marine mammals and fowl and including
Influenza viruses are constantly evolving due to the mechanism of antigenic drift. This results in seasonal vaccination to target only specific strains, which puts us in a race against the clock in the prevention of the next pandemic. One key to solving this is the development of a universal influenza vaccine, which would elicit a broad antibody response. This would target either multiple strains or strains from the past, present, and future in a single vaccination. As vaccine may target sites such
conserved pocket in the stem region shared with the diverse influenza subtyupes and function critical for viral fusion. Therefore, characterizing permitted evolutionary routes of the virus over the course of F10-type immune selection may serve as templates for the design of universal influenza vaccine and treatment strategies against all types of influenza viruses including those emergent pandemic strains. Selection of VN/04 (H5N1) or A/PR/8 virus escape mutants with F10 antibody was performed in MDCK
Influenza is an acute respiratory illness caused by infection of influenza A and B viruses. The disease can affect both the upper and lower respiratory tract and is often followed by systemic signs and symptoms, such as: sudden onset of fever, chills, non-productive cough, myalgias (muscle pain), headache, nasal congestion, sore throat, and fatigue. (Cox et al.1998). Influenza viruses evolve continuously, challenging mammalian and avian hosts with new variants and causing complex epidemic patterns
discovered new virus with strand called Z1H1which is a combination of an H5N1 and zombie virus. Respiratory infection caused by virus is severe leading to a rapid and painful death. The NU zombie research facility initiated a project to design a preventative vaccine and defeat zombie virus in this battle. Latest technologies available in NU zombie research facility give an opportunity to design virus particle (VLP). Because preventative vaccine is desired, exposure to very similar virus or its part
The Influenza virus is a unique respiratory viral disease that can have serious economic and social disruption to society. The virus is airborne transmitted through droplets release by coughing or sneezing from an infected person or by touching infected surfaces. Symptoms range from mild to severe and may even result in death. People with the virus usually experience fever, headache, shivering, muscle pain and cough, which can lead to more severe respiratory illness such as pneumonia. People most
swine flu, scientifically known as H1N1. Swine flu is a respiratory infection derived from the influenza virus. The virus contains genetic materials from human, swine, and avian flu viruses. It was first identified in spring 2009, and since then has spread rapidly across the globe. The infection’s spread has been verified as a global pandemic by the World Health Organization. As soon as the swine flu virus was isolated, scientists quickly developed a swine flu vaccine. Four vaccines have been approved
