On Friday, the World Health Organization (WHO) has allowed Johnson and Johnson's coronavirus or Janssen vaccine shots for emergency use. It is manufactured by Janssen Vaccines in Leiden, a Dutch subsidiary of US company Johnson & Johnson.

It is the third coronavirus vaccine after BioNTech's Pfizer and Oxford's AstraZeneca that got support from the WHO and making it one of the first to have a single shot as compared to other vaccines. The WHO has also welcomed the one-shot dose as facilitating inoculation logistics.

The J&J vaccine is going to be cost-friendly as compared to Pfizer and Moderna and can be stored in a fridge rather than a freezer.

The vaccine listing covers emergency use in all nations and extensive research that took place in three continents found that the J&J vaccine was 85% efficacy in protecting against covid cases.

On Thursday, J&J's chief researcher Paul Stoffels told Reuters that the organization hopes to make over 3 billion doses of the Janssen vaccine by 2022, after already swearing to dispatch 1 billion internationally before the end of this year.

"Each new, effective, and safe tool against SARS Cov-2 is one more step closer to curb the spread of the pandemic," the WHO Director-General Tedros Adhanom Ghebreyesus stated.

"However, these tools will only help provide results when they are made accessible to all people and all nations, Ghebreyesus added.

The WHO said under an emergency use listing, organizations need to focus on producing more safety and efficacy data to obtain full licensing by assigned authorities.

Many nations like the UK, Canada, and EU have ordered Janssen coronavirus vaccine doses, and 500 million doses are ordered via the WHO's COVAX scheme for supply in poor countries, BBC reported.
