The World Health Organization on Thursday granted emergency validation to the Pfizer-BioNTech COVID-19 vaccine, AFP reports.
The approval paves the way for countries worldwide to quickly approve its import and distribution.
WHO said the Pfizer/BioNTech vaccine was the first to receive its "emergency validation" since the novel coronavirus first broke out in China a year ago.
"This is a very positive step towards ensuring global access to COVID-19 vaccines," said Mariangela Simao, a top WHO official tasked with ensuring access to medicines.
"But I want to emphasize the need for an even greater global effort to achieve enough vaccine supply to meet the needs of priority populations everywhere," she said in a statement.
WHO said its emergency use listing opens the way for regulators in different countries to approve the import and distribution of the vaccine.
WHO convened its own experts and those from around the world to review the data on the Pfizer/BioNTech vaccine’s "safety, efficacy and quality," weighing the benefits against the risks.
"The review found that the vaccine met the must-have criteria for safety and efficacy set out by WHO, and that the benefits of using the vaccine to address COVID-19 offset potential risks," it said.
Several countries have already began vaccination campaigns using the Pfizer/BioNTech vaccine, including Israel and the US.
The European Medicines Agency (EMA) recently gave its approval to the vaccine as well, paving the way for citizens of the European Union to be vaccinated against the disease.
