Assessment of Disruption of Routine Childhood Immunization in Developing Countries Due to Pandemic

The COVID-19 pandemic, also known as the coronavirus pandemic, began in March 2020 and was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The pandemic impacted the global healthcare system. It caused the biggest threat to the global routine immunization system. Routine childhood immunization was disrupted globally, particularly in the early pandemic period. This review discusses the severity of disruptions to routine immunization, their root causes, and remedial measures to lessen these disruptions. It is essential to maintain routine medical care, especially routine immunization, to avert morbidity and death from several diseases that vaccines can prevent, including a pandemic.
