With the Delta (B1617.2) variant outpacing COVID-19 vaccination in many countries, the world is at a perilous point in the pandemic, the head of the World Health Organization (WHO) said today.The warning comes a day after the WHO reported that cases have risen for the second week in a row, with nearly all regions reporting illness spikes.At a briefing today, WHO Director-General Tedros Adhanom Ghebreyesus, PhD, warned that variants are winning the race against vaccines, due to inequitable vaccine distribution—factors that threaten global economic recovery.Some countries with high vaccination coverage are planning the rollout of booster vaccine doses and dropping public health measures, as if the pandemic is over, he said.
