Y1 - 2022 N1 - T2 - Current Diagnosis & Treatment: Pediatrics, 26e AB - Immunization is widely recognized as 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 2019 (COVID-19) pandemic disrupted health care delivery and was associated with declines in routine vaccination coverage among infants, children, and adolescents; efforts to regain these coverage losses are paramount.
