Schedule of vaccination
As with all immunizations, whether it is available or required, and under what circumstances, varies according to the decisions made by local public health agencies. Children under the age of two years fail to mount an adequate response to the 23-valent adult vaccine, and so a pneumococcal conjugate vaccine is used. While this covers only seven strains out of more than ninety strains, these seven strains cause 80% to 90% of cases of severe pneumococcal disease, and it is considered to be nearly 100% effective against these strains. United Kingdom
The UK childhood vaccination schedule for infants born after 31 December 2019, consists of a primary course of one dose at twelve weeks of age with a second dose at one year of age. For infants born before 1 January 2020 and those in Scotland, the childhood vaccination schedule consists of a primary course of two doses at eight and sixteen weeks of age with a final third dose at one year of age.Children at special risk (e.g., sickle cell disease and asplenia) require as full protection as can be achieved using the conjugated vaccine, with the more extensive polysaccharide vaccine given after the second year of life:

United States
In 2001, the Centers for Disease Control and Prevention (CDC), upon advice from its Advisory Committee on Immunization Practices (ACIP), recommended the vaccine be administered to every infant and young child in the United States. The resulting demand outstripped production, creating shortages not resolved until 2004.
Pneumococcal conjugate vaccine is a pneumococcal vaccine and a conjugate vaccine used to protect infants, young children, and adults against disease caused by the bacterium Streptococcus pneumoniae (pneumococcus). It contains purified capsular polysaccharide of pneumococcal serotypes conjugated to a carrier protein to improve antibody response compared to the pneumococcal polysaccharide vaccine. The World Health Organization (WHO) recommends the use of the conjugate vaccine in routine immunizations given to children.Vaccine-mediated immunity is "conferred mainly by opsonophagocytic killing of S. pneumoniae. "The most common side effects in children are decreased appetite, fever (only very common in children aged six weeks to five years), irritability, reactions at the site of injection (reddening or hardening of the skin, swelling, pain or tenderness), somnolence (sleepiness) and poor quality sleep. In adults and the elderly, the most common side effects are decreased appetite, headaches, diarrhea, fever (only very common in adults aged 18 to 29 years), vomiting (only very common in adults aged 18 to 49 years), rash, reactions at the site of injection, limitation of arm movement, arthralgia and myalgia (joint and muscle pain), chills and fatigue.
