The World Health Organization has called out a "shocking imbalance" in the global distribution of vaccines, with rich nations far outstripping poorer countries in their immunization drives.
WHO executive director Tedros Adhanom Ghebreyesus said that only 0.2 percent of vaccine doses administered globally so far have gone to low-income countries.
"On average, in high-income countries, almost one-in-four people have received a vaccine. In low-income countries, it's one in more than 500," Tedros said during a press briefing on Friday.
