Pneumococcal disease is caused by Streptococcus pneumoniae, a bacterium that has more than 90 serotypes. Only a few of these serotypes produce the majority of invasive pneumococcal disease.
Pneumococcal disease is spread from person to person by droplets in the air. The pneumococci bacteria are common inhabitants of the human respiratory tract.
Pneumococcal pneumonia is the most common disease caused by pneumococcal infection and can occur in combination with bacteremia and/or meningitis, or it can occur alone.
Isolated pneumococcal pneumonia is not considered an invasive disease, but it can be severe. It is estimated that 175,000 cases occur each year in the USA. The fatality rate is 5-7 percent and could be much higher in the elderly, says the CDC. Globally, pneumococcal pneumonia is estimated to cause about 500,000 deaths and 30 million episodes in adults 70 years and older annually.
- Pneumovax 23: is a vaccine that protects against infection by 23 types of pneumococcal bacteria, which are common and often cause serious illnesses.
- Prevnar 13: is a vaccine that protects against invasive disease caused by Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F
- 20vPnC (PF-06482077): is a 20-Valent pneumococcal conjugate vaccine candidate to help protect from a substantial invasive pneumococcal disease and pneumonia burden.
