CAPE TOWN, South Africa (AP) — Preventive cholera vaccination programs will restart globally after they were halted for nearly four years due to a vaccine shortage, the World Health Organization said Wednesday. In a joint statement, WHO, vaccine alliance GAVI and the United Nations Children's Fund said stocks of oral cholera vaccines in the global stockpile they manage had improved to nearly 70 million doses last year. The vaccines are distributed free to countries that need them, but they had to be used only in reaction to outbreaks rather than preventative campaigns after a shortage was announced in 2022 because of a surge in demand.
