WHO exec: donated COVID-19 vaccines with short shelf life 'major problem'

Wealthy countries donating COVID-19 vaccines with a relatively short shelf life has been a 'major problem' for the COVAX dose sharing programme, a senior official at the World Health Organization said on Thursday. Kate O'Brien, the WHO's vaccine director, said in a briefing the proportion of wasted doses is smaller in countries receiving doses through COVAX than in many high-income countries. Her comments come as concerns grow that many African countries are finding they do not have the capacity to get shots in arms before they expire.
