It is a travesty that some countries still have not had enough access to vaccines to begin inoculating health workers and the most vulnerable people against COVID-19, the head of the World Health Organization said on Tuesday.
"Scaling up production and equitable distribution remains the major barrier to ending the acute stage of the COVID-19 pandemic," WHO Director-General Tedros Adhanom Ghebreyesus told a news conference.
"It's a travesty that in some countries health workers and those at-risk groups remain completely unvaccinated."
