The unequal distribution of vaccines which protect against COVID-19 is the weak point in efforts to combat the disease in the Americas, the Pan American Health Organization said on Wednesday.
"A handful of companies produce all the world’s supply of COVID-19 vaccines," PAHO Director Dr. Carissa Etienne said during the organization’s weekly virtual briefing.
"Many of them are letting price and country of origin, not need, determine how doses are rolled out, so much of today’s vaccine supply remains in the hands of wealthy nations around the world."
Countries are also suffering because of production delays, leaving them waiting for doses purchased months ago, she said. (Reuters)
