Public health agencies are warning Haiti has yet to receive a single dose of COVID-19 vaccine for its 11 million people, with further delays now likely to postpone a scheduled first shipment of vaccines due to arrive in May. The Pan American Health Organization says Haiti’s government failed to apply for a pilot program that would have sped up deliveries of doses under the U.N.'s COVAX initiative. Haiti remains in deep political turmoil after U.S.-backed President Jovenel Moïse refused to leave office after his term expired. In February, the Biden administration sided with Moïse's claim that he can serve for another year.
