Pneumococcal vaccines help protect against bacterial infections caused by Streptococcus pneumoniae (pneumococci).

There are more than 90 different types of pneumococci. Vaccines are directed against many of the types most likely to cause serious disease. Two types of pneumococcal vaccines are available:

  • The conjugate vaccine (PCV13) protects against 13 types of pneumococcal bacteria (pneumococci).

  • The polysaccharide vaccine (PPSV23) protects against 23 types of pneumococci.

Administration of Pneumococcal Vaccine

The PCV13 vaccine is injected into a muscle. The number of doses depends on the person's age. It is routinely recommended for

The PCV13 vaccine is also recommended for people aged 6 to 64 who are at high risk of developing pneumococcal infections. These people include

The PPSV23 vaccine is injected under the skin or into a muscle. It is routinely recommended for

  • All people aged 65 years and over

If people aged 65 years and over got the PPSV23 vaccine when they were under 65, they are given a second dose, at least 5 years after the first. For example, if they were given the first dose at age 64, they are given the second dose at age 69 or later.

The PPSV23 vaccine is also recommended for people aged 2 to 64 who are at high risk of developing pneumococcal infections. These people include the following:

PPSV23 vaccine is effective in preventing some of the serious complications of pneumococcal pneumonia (such bloodstream infections), but it is less effective in debilitated older people. If people are given a pneumococcal vaccine for the first time at age 65, they are given the PCV13 vaccine first and the PPSV23 vaccine 1 year later. If people have already been vaccinated with PPSV23, PCV13 should be given at least 1 year after the most recent dose of PPSV23.

If people have a temporary illness, doctors usually wait to give the vaccine until the illness resolves (see also CDC: Who Should NOT Get Vaccinated With These Vaccines?).

Side Effects of Pneumococcal Vaccine

Occasionally, the injection site becomes painful and red. Other side effects include fever, irritability, drowsiness, loss of appetite, and vomiting.

Human Immunodeficiency Virus (HIV) Infection
Human immunodeficiency virus (HIV) infection is a viral infection that progressively destroys certain white blood cells. Untreated, it usually leads to acquired immunodeficiency syndrome (AIDS). Transmission of HIV requires contact with bodily fluid that contains the virus or cells infected with the virus. Which of the following is not a bodily fluid that commonly transmits HIV?
