The pneumococcal vaccine prevents serious blood, brain, and lung infections from the Streptococcus pneumoniae bacteria. Such infections are called pneumococcal disease -- they also include pneumonia, meningitis, and septicemia.
Pneumococcal disease is a serious health threat that can lead to death. Many strains of Streptococcus pneumonia are resistant to antibiotics. Infection with the bacteria is a leading cause of serious illness in adults and children worldwide. In the U.S. alone, more people...
Some people get much sicker. Influenza can lead to pneumonia and can be dangerous for people with heart or breathing conditions. It can cause high fever, diarrhea, and seizures in children. On average, 226,000 people are hospitalized every year because of influenza and 36,000 die - mostly elderly.
Live, attenuated influenza vaccine (LAIV) contains live but attenuated (weakened) influenza virus. It is sprayed into the nostrils.
Inactivated influenza vaccine, sometimes called the “flu shot,” is given by injection. Inactivated influenza vaccine is described in a separate Vaccine Information Statement.
Influenza viruses are always changing. Because of this, influenza vaccines are updated every year, and an annual vaccination is recommended.
Each year scientists try to match the viruses in the vaccine to those most likely to cause flu that year. When there is a close match the vaccine protects most people from serious influenza-related illness. But even when the there is not a close match, the vaccine provides some protection.
Influenza vaccine will not prevent “influenza-like” illnesses caused by other viruses. It takes up to 2 weeks for protection to develop after the vaccination. Protection lasts up to a year.
LAIV does not contain thimerosal or other preservatives.
