The World Health Organization (WHO) on Friday approved the Johnson & Johnson's Covid-19 vaccine for emergency use, paving the way for the one-shot dose to be used as part of the United Nation's international vaccine distribution effort. "Every new, safe and effective tool against Covid-19 is another step closer to controlling the pandemic," WHO chief Tedros Adhanom Ghebreyesus said.

It is the third coronavirus vaccine after the two-shot regimens of Pfizer-BioNTech and AstraZeneca to receive backing from the WHO, and the first requiring just a single injection. The vaccine from Johnson &Johnson; is the first to be listed by WHO as a single dose regimen, which should facilitate vaccination logistics in all countries.

"The ample data from large clinical trials shared by the company also shows that the vaccine is effective in older populations," according to the global health body. WHO and a team of assessors from all regions adopted what is called an 'abbreviated assessment' based on outcomes of the EMA review. The WHO assessment also considered suitability requirements such as cold chain storage and risk management plans.

WHO senior adviser Bruce Aylward said that the Johnson & Johnson vaccine, which does not require an ultracold chain, was "even better suited to some of the countries that are worst-hit, affected by the pandemic". While the vaccine needs to be stored at -20 degrees, which may prove challenging in some environments, it can be kept for three months at 2-8°C and it has a long shelf life of two years.

Studies have shown that the Johnson & Johnson vaccine is 66% effective in protecting any cases of moderate to severe illness and 85% effective against severe cases of COVID-19. It completely prevented hospitalizations and death four weeks after inoculation.
