Vaccines by disease: Learning more about the pneumococcal conjugate vaccine

This vaccine protects against the pneumococcus bacteria, formerly the leading cause of bacterial meningitis in the United States. Pneumococcal disease also may lead to other health conditions including blood infection, pneumonia or ear infections. Brain damage or deafness may occur in those recovering from meningitis.

Before a pneumococcal vaccine was available, infection caused by the pneumococcus bacteria led to more than 700 cases of meningitis, 13,000 blood infections and 5 million ear infections. Some strains of pneumococcus bacteria have become antibiotic resistant. Because of this, it is even more imperative to receive the pneumococcal conjugate vaccine.

Prevention is the key to not contracting pneumococcal disease, and the most effective preventive method is the pneumococcal conjugate vaccine.


Who should receive the pneumococcal conjugate vaccine?
Children under the age of 2 should receive a routine schedule of four doses with one dose being received at the following ages:

  • 2 months
  • 4 months
  • 6 months
  • 12 to 15 months

Children between the ages of 2 and 5 years who were not vaccinated against pneumococcal disease and are at high risk of becoming infected with this disease should receive the pneumococcal conjugate vaccine. This includes children with:

  • sickle cell disease, HIV/AIDS, chronic heart disease or liver disease
  • a damaged spleen or no spleen
  • weakened immune systems due to other diseases or medications

If a child has had a life-threatening allergic reaction to a component of the pneumococcal conjugate vaccine or to a previous dosage of this vaccine, the vaccine should not be used. Children with minor illnesses should receive the pneumococcal conjugate vaccine, but those with moderate-to-severe illnesses should wait until they are fully recovered to receive this vaccine.

Review the vaccination schedule for those who start late on a vaccine or are more than one month behind. 
 

When did the pneumococcal conjugate vaccine become available?
The first pneumococcal vaccine was Food and Drug Administration (FDA) licensed in the United States in 1977 and still is in use today for older children and adults. In February 2000, the pneumococcal conjugate vaccine (PCV7) was FDA licensed for use in infants, toddlers and preschoolers.

How does someone become infected with pneumococcal disease?
Pneumococcous bacteria are spread by person-to-person contact.

How effective is the pneumococcal conjugate vaccine?
This vaccine is 97 percent effective in protecting against seven types of pneumococcus bacteria contained in the vaccine and 89 percent effective in preventing disease caused by all strains of pneumococcus if all doses are received. The pneumococcal conjugate vaccine also reduces the number of ear infections by 10 percent and the need for middle ear tubes or PE tubes by 20 percent.

Are there any serious side effects of the pneumococcal conjugate vaccine?
Mild side effects may include:

  • injection-site soreness
  • fever
  • loss of appetite
  • fussiness and drowsiness

How do I learn more about this vaccine?
The best person to ask about this or any vaccine is your child’s pediatrician or your primary health care provider. Your provider can answer your questions and give you more information on the pneumococcal conjugate vaccine.

Immunization is the best thing you can do for your child to protect against pneumococcal disease.
