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

Area of Science:

• Public Health
• Epidemiology
• Immunization Programs

Background:

• The COVID-19 pandemic, caused by SARS-CoV-2, began in March 2020.
• It posed a significant threat to global healthcare systems and routine immunization services.
• Disruptions were particularly severe for childhood immunizations during the early pandemic.

Purpose of the Study:

• To review the severity of disruptions to routine immunization during the pandemic.
• To identify the root causes of these immunization service interruptions.
• To discuss remedial measures for mitigating these disruptions.

Main Methods:

• This study is a review of existing literature and data.
• Analysis of the impact of the pandemic on global immunization schedules.
• Examination of strategies to address vaccination gaps.

Main Results:

• Routine childhood immunization experienced unprecedented global disruption.
• The pandemic's impact threatened the stability of established immunization programs.
• Missed vaccinations increase health risks for children and the general population.

Conclusions:

• Maintaining routine immunization is vital to prevent vaccine-preventable diseases.
• Healthcare system responses to pandemics must prioritize immunization continuity.
• Implementing catch-up vaccination strategies is essential post-pandemic to mitigate risks.
