Influenza. Also called as flu.
Seasonal flu vaccines carry an H1N1 component, an H3N2 strain and an influenza B strain. The H1N1 component is not the Novel H1N1 strain that is in the swine flu vaccine
Adults should get seasonal influenza vaccine annually.
A flu shot will prevent the type of influenza virus or viruses that have been used to make the vaccine. A,nd it may sometimes protect against a different, but very similar, strain.
Typically the flu vaccine is trivalent, with three strains.
Two type A viruses and one Type B virus.
The influenza virus contains Both DNA and RNA.Its an exception.
There are four types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. Influenza type C infections generally cause a mild respiratory illness and are not thought to cause epidemics. Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people.A, B and C cause a severe upper respiratory infections. These are more than 'just a cold.'
In the US, approximately 36,000 die of seasonal flu each year. Mostly the aged and infirm or the very young infants.
They are caused by two different kinds of viruses. There are three types of influenza viruses that have been classified according to the types of proteins they have. There are Type A, Type B, and Type C influenza viruses. Type A and B each have many different strains. Type C does not.Type A influenza is one of the more common types we see in the seasonal flu among humans and it is also a very common type that many other animals get. It has subtypes and strains that differ, which is why having one subtype will not give you immunity from all the other subtypes and strains.Type B influenza is also a common type among humans and is found only in humans. It is not divided into subtypes but there are multiple strains.Type C has been found in humans, pigs, and dogs. The symptoms are usually very mild, milder than those of Type A and B influenza viruses, and it typically doesn't cause epidemics. It is not divided into different subtypes or strains.
The CDC-approved trivalent vaccines for the 2011-2012 flu season contain and will protect against the following three flu virus strains: 1. Type A Influenza/California/7/09 (H1N1)-like virus (Pandemic (H1N1) 2009 influenza virus) 2. Type A Influenza/Perth/16/2009/ (H3N2)-like virus 3. Type B Influenza/Brisbane/60/2008-like virus
Yes it can. According to the Centers for Disease Control and Prevention:The live attenuated influenza vaccine viruses in LAIV (seasonal vaccine and 2009 H1N1 monovalent vaccine) can cause a positive result on a rapid influenza diagnostic test. The tests are designed to detect influenza viruses and cannot differentiate between live attenuated and wild-type influenza viruses. A positive test in a person who recently (in the previous 7 days) received LAIV and who also has an influenza-like illness could be caused by either LAIV or wild-type influenza virus.
