The Pan American Health Organization (PAHO) has issued an urgent call to countries across the Americas to ramp up vaccination efforts and strengthen routine disease prevention measures, warning that stagnating immunization rates leave populations vulnerable to preventable outbreaks. In a recent public statement, the regional health body highlighted that the COVID-19 pandemic caused significant disruptions to global immunization programs, leaving millions of children and at-risk adults across the region without access to life-saving vaccines for diseases like measles, polio, influenza, and hepatitis. These gaps in coverage have already led to a resurgence of several vaccine-preventable illnesses in multiple countries across the Americas over the past two years. PAHO officials emphasize that routine vaccination is one of the most cost-effective public health interventions available, saving millions of lives annually and reducing the burden on strained healthcare systems. The organization is urging national governments to allocate additional funding to immunization programs, launch targeted public awareness campaigns to counter vaccine misinformation, and train community health workers to improve access to vaccination services in remote and underserved areas. PAHO also stands ready to provide technical support, vaccine procurement assistance, and resource coordination to help member states meet their vaccination coverage targets by 2030, with the ultimate goal of eliminating key vaccine-preventable diseases across the region.
