In light of the sustained decline in pertussis vaccination coverage, mainly during the COVID-19 pandemic, and in the context of the current global resurgence of pertussis cases—with significant increases in several countries in the Americas Region—the ¶¶ÒùÊÓƵ/World Health Organization (¶¶ÒùÊÓƵ/WHO) urges Member States to strengthen their epidemiological surveillance systems and maintain monitoring continuous, detailed, and disaggregated vaccination coverage among children, with special attention to children under 1 year of age and under 5 years of age. It is a priority to identify in a timely manner population groups that do not receive pertussis vaccines with the recommended doses, in particular unvaccinated infants or infants with incomplete schedules, in order to implement corrective actions to close immunization gaps and prevent outbreaks.
