What is Pneumococcal Disease?

Pneumococcal disease is an infection caused by a certain type of bacteria called Streptococcus pneumonia. Sometimes these germs get into parts of the body that are normally free from germs. This is called invasive disease. These types of infections can be very severe leading to death or hospitalization.

Symptoms depend on which part of the body is infected.


This is a 6-month study which includes (2) visits and (3) phone calls. Compensation is up to $405 for time and travel may be available to those who qualify.


Why should I care?

Pneumococcus bacteria can kill you…

It is estimated that 150,000 are hospitalized in the U.S. every year for pneumococcal pneumonia. Pneumococcal meningitis is an infection in the lining of the brain or spinal cord. This infection kills approximately 3,250 people a year. Approximately 1 in 30 children and 1 in 8 adults with pneumococcal bacteremia will die from the illness. Older adults are at greater risk than young adults for serious complications from pneumococcal disease because our immune system weakens as we age.


Vaccines are the best way to prevent pneumococcal disease. Even if you had pneumococcal disease in the past, this will not prevent you from becoming re-infected. The CDC recommends pneumococcal vaccines for children and adults. Pneumococcal vaccines currently available in the United States:

  • Pneumococcal conjugate vaccines (PCV13, PCV15, or PCV20)
  • Pneumococcal polysaccharide vaccine (PPSV23)


These vaccines do not protect against all types of pneumococcal bacteria. The protection from these vaccines is good but not perfect (or 100%). For these two reasons, there is still a chance someone can develop pneumococcal disease after vaccination. This study is being conducted to see if pneumococcal infection protection can be improved. Each person who enrolls in this study will receive either the PVC20 pneumococcal vaccine or the investigational study pneumococcal vaccine.
