Aug 25 (Reuters) – The World Health Organization Director General Tedros Adhanom Ghebreyesus said on Wednesday that the data on the benefits and safety of a COVID-19 vaccine booster shot is inconclusive.

“When some countries afford to have the booster and others are not even vaccinating the first and second round, it’s a moral issue,” he said during a media briefing.
