Flu Vaccine Flu Vaccines Influenza, or flu for short, is a respiratory infection caused by a variety of viruses. Its symptoms include nasal and lung congestion, sore throat, fever, chills, cough, sneezes, fatigue, headache, and sore muscles and joints. The viruses can pass through the air and enter the body through the nose or mouth. The viruses can spread easily and it is very contagious. Anyone can get the flu but you can avoid getting it by taking the flu vaccine. After years of trying to discover a vaccine for the flu, there is still no fully effective general flu vaccine. A vaccine that could prevent influenza from occurring and/or lessen the severity of symptoms would be invaluable. However, influenza has been thought to be almost impossible to vaccinate against because the virus itself mutates rapidly. Scientists make a different vaccine every year because the strains of flu viruses change from year to year. This causes the flu vaccine shot to be a dangerous vaccine that can cause more harm than good.
