GENEVA -- UN chief Antonio Guterres on Thursday branded rich nations' vaccine hogging as immoral and stupid, saying choking off poorer countries' access to jabs risked undermining their own defenses against the pandemic.
The World Health Organization said every country that had fully immunized more than 40% of its population was doing too little to stop the COVID-19 crisis, as they should be ensuring doses go to nations left wide open to the virus.
The WHO wanted 10% of the population in every country fully jabbed by the end of September -- a target missed in 56 countries, "through no fault of their own", said the organization's chief Tedros Adhanom Ghebreyesus.
The UN health agency said 1.5 billion vaccine doses were now being manufactured every month -- with less than one week's production needed to reach the 10% target.
"Vaccine inequality is aiding and abetting the COVID-19 pandemic," Guterres told a virtual press conference alongside Tedros.
"It is allowing variants to develop and run wild, condemning the world to millions more deaths, and prolonging an economic slowdown that could cost trillions of dollars."
MORE ON VACCINES:
Guterres said that if the virus spread in areas with few vaccinated people, the greater the chances of a variant emerging that could become resistant to vaccines.
"All the vaccination effort made in developed countries to vaccinate the whole of the population, one, two or three times -- all that effort will fall apart. And these people will not be protected.
"So not to have equitable distribution of vaccines is not only a question of being immoral: it is also a question of being stupid."
'Precipice of failure'
Tedros said more than 6.4 billion vaccine doses had now been administered, and almost a third of the world's population was fully vaccinated against COVID-19.
However, "those numbers mask a horrifying inequity," he said.
"We stand on the precipice of failure" if vaccines are not immediately made widely available, the director-general said.
Tedros said there were enough doses being produced to achieve the WHO's next target of seeing 40% in every country vaccinated by the end of the year -- provided they are distributed equitably.
Meanwhile Tedros also said that the WHO had now finalized a clinical case definition for post-COVID condition, often called Long COVID.
The definition states that symptoms appear within three months of infection, last for at least two months and cannot be explained by an alternative diagnosis.
Common symptoms include fatigue, shortness of breath and cognitive dysfunction. They may appear following recovery from acute-stage COVID-19, or persist from the initial illness. Symptoms may also fluctuate over time.
"This standardized definition will help clinicians to identify patients more easily and provide them the appropriate care, and is crucial for advancing recognition and research," Tedros said.
