Flu vaccines are important to get each year to prevent getting sick and dealing with the problems associated with the influenza virus. No matter how healthy or strong your immune system is you should get a flu vaccination. There are two types of flu vaccines. One type contains killed particles of the virus given in an intravenous shot form and the other contains weak flu particles that are found in a nasal spray. In general vaccination is particularly recommended for people who are at a higher risk to get the flu, or even are in contact with people who may be at a higher risk.
