AB  - Immunization  is  one  of  the  greatest  public  health  achievements  of  modern  times.  Largely  due  to  immunization,  the  annual  incidences  of  diphtheria,  paralytic  poliomyelitis,  measles,  mumps,  rubella,  and  Haemophilus  influenzae  type  b  (Hib)  in  the  United  States  have  fallen  by  more  than  99%  compared  with  the  average  annual  incidences  of  these  diseases  in  the  20th  century.  Invasive  pneumococcal  disease  in  children  younger  than  5  years  has  declined  steeply  since  routine  pneumococcal  vaccination  began  in  2000.  Similarly,  rotavirus  vaccination  is  associated  with  substantial  declines  in  hospitalizations  and  emergency  department  visits  for  diarrheal  illnesses  in  young  children.  Childhood  immunization  has  also  led,  through  herd  immunity,  to  significant  decreases  in  several  infectious  illnesses  in  adults,  including  pneumococcal,  rotavirus,  and  varicella  disease.  The  coronavirus  disease  2019  (COVID-19)  pandemic  disrupted  health  care  delivery  and  was  associated  with  declines  in  routine  vaccination  for  infants,  children,  and  adolescents;  efforts  to  regain  these  coverage  losses  are  ongoing.
