BRASILIA (Reuters) - Vaccinating 20% of the population of Latin America and the Caribbean against COVID-19 will cost more than $2 billion but low income countries will be helped by the COVAX Facility led by the World Health Organization, its regional branch said on Wednesday.According to the Pan American Health Organization (PAHO), COVAX aims to deploy at least 2 billion doses of COVID-19 vaccines by the end of 2021. “This is a remarkable figure. But we also know that it won’t be sufficient to vaccinate everyone, at least not at first,” , PAHO Assistant Director Jarbas Barbosa said. PAHO is working to ensure every nation in the region that is interested will have access to the COVAX Facility, a coalition that aims to provide equitable access to eventual COVID-19 vaccines.
