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: conjugate and polysaccharide.
The conjugate vaccine PCV13 protects against 13 types of pneumococcal bacteria (pneumococci).
The conjugate vaccine PCV15 protects against 15 types of pneumococci.
The conjugate vaccine PCV20 protects against 20 types of pneumococci.
The polysaccharide vaccine PPSV23 protects against 23 types of pneumococci.
Administration of Pneumococcal Vaccine
All of the pneumococcal vaccines are injected into a muscle. Recommendations and the vaccine given depend on the person's age and other factors:
All children: Most children are given the PCV13 vaccine, typically at age 2 months, 4 months, 6 months, and 12 to 15 months as a part of routine childhood vaccination Childhood Vaccination Schedule Most doctors follow the vaccination schedule recommended by the Centers for Disease Control and Prevention (CDC—see the schedule for infants and children and the schedule for older children... read more .
People aged 65 years and over: Those who have not previously received a conjugate vaccine or whose vaccination history is unknown can receive PCV20 or PCV15 followed by a dose of PPSV23 at least 1 year later.
People aged 19 to 64 years: Those who have certain conditions or risk factors (see below), have not previously received a conjugate vaccine, and whose vaccination history is unknown can receive PCV20 or PCV15 followed by a dose of PPSV23 at least 8 weeks later.
People aged 19 to 64 years who have any of the following should receive pneumococcal vaccine:

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.
