Pneumococcal disease is a serious infection caused by a bacteria. Pneumococcal bacteria can infect the sinuses and inner ear. It can also infect the lungs, blood, and brain and these conditions can be fatal.

Pneumococcal polysaccharides vaccine (PPSV) is used to prevent infection caused by pneumococcal bacteria. PPSV contains 23 of the most common types of pneumococcal bacteria.

PPSV works by exposing you to a small dose of the bacteria or a protein from the bacteria, which causes your body to develop immunity to the disease. PPSV will not treat an active infection that has already developed in the body.

PPSV is for use only in adults and children who are at least 2 years old. For children younger than 2 years old, another vaccine called Prevnar (pneumococcal conjugate vaccine [PCV] 7-valent) is used, usually given between the ages of 2 months and 15 months.

Like any vaccine, PPSV may not provide protection from disease in every person.

Relenza (zanamivir) is an antiviral medicine that blocks the actions of viruses in your body.

Relenza is used to treat flu symptoms caused by influenza virus in people who have had symptoms for less than 2 days.

Relenza may also be given to prevent influenza in people who may be exposed but do not yet have symptoms. Zanamivir will not treat the common cold.

Relenza should not be used in place of getting a yearly flu shot. The Centers for Disease Control recommends an annual flu shot to help protect you each year from new strains of influenza virus.
