evidence: Variants like Delta are "currently winning the race against vaccines" said the World Health Organization (WHO) chief, Tedros Adhanom Ghebreyesus on Wednesday, pinning the blame squarely on a lack of equitable vaccine production and distribution. [...] Tedros warned that far too many countries are seeing "sharp spikes in cases and hospitalization", while rich nations with high inoculation rates, were dropping public health measures "as though the pandemic is already over." [...] Tedros reminded that ‘vaccine nationalism’, where a handful of nations have taken the lion’s share, is ‘morally indefensible’ and an ineffective public health strategy against a respiratory virus that is mutating quickly and becoming increasingly successful at infecting new hosts.
