Influenza

Flu is a respiratory infection caused by a number of viruses. The viruses pass through the air and enter your body through your nose or mouth. Between 5% and 20% of people in the U.S. get the flu each year. The flu can be serious or even deadly for elderly people, newborn babies and people with certain chronic illnesses. Symptoms of the flu come on suddenly and are worse than those of the common cold. They may include

Influenza

The flu is an infection caused by a virus in the upper breathing passages that may also spread to the lungs. Symptoms include fever, headache, general aches and pains, and extreme exhaustion. The flu is a contagious disease in which the influenza virus is spread through the air by the coughing and sneezing of people who are already infected. The virus is inhaled into the lungs where it attacks tissues involved in breathing. People with the flu usually feel sick rather suddenly, with symptoms that may include fever, headache, and feeling very tired. These symptoms are sometimes followed by coughing and a stuffy or runny nose.

Influenza

The flu is a highly contagious respiratory viral infection. Spread easily by coughing, sneezing, and poor hygiene. Vaccines have been only partially effective because of new and different viral strains that are constantly changing.

Flu, Swine

Influenza viruses are small RNA viruses that infect many mammals, including humans, birds, and swine. Before 2009, swine influenza predominately affected swine and was not transmitted often or easily to people. Even in the isolated instances in which swine influenza infected people, it had very limited ability to spread from person to person. Most cases were directly linked to contact with swine through farming or at fairs.

Influenza A

Influenza A (H1N1) 2009 Monovalent Vaccine is a sub-unit (purified surface antigen) influenza virus vaccine prepared from virus propagated in the allantoic cavity of embryonated hens eggs inoculated with a specific type of influenza virus suspension containing neomycin and polymyxin. The influenza virus strain is harvested and clarified by centrifugation and filtration prior to inactivation with betapropiolactone. The inactivated virus is concentrated and purified by zonal centrifugation. The surface antigens, hemagglutinin and neuraminidase, are obtained from the influenza virus particle by further centrifugation in the presence of nonylphenol ethoxylate, a process which removes most of the internal proteins. The nonylphenol ethoxylate is removed from the surface antigen preparation. Influenza A (H1N1) 2009 Monovalent Vaccine is an inactivated influenza virus vaccine indicated for active immunization of persons 4 years of age and older against influenza disease caused by pandemic (H1N1) 2009 virus (1). DOSAGE AND ADMINISTRATION Based on currently available information the vaccination regimen is as follows:...
