The key emergency committee of the World Health Organization (WHO) said Friday that a lack of data on vaccine safety is a barrier to ensuring a quick and equitable global supply of vaccines and recommended against countries issuing vaccine passports.

"If you look at the recommendation made by the committee around vaccination for travelers, it says at the present time that the committee does not recommend including a requirement of proof of vaccination for international travel," said Dr. Mike Ryan, head of the WHO's emergencies program.

"It is not because that would be a good idea in the future," he said. "But because we are lacking critical evidence regarding whether or not these persons were vaccinated, continued to be affected or continue to transmit disease."

It recommended countries not require vaccination proof from incoming travelers but
advised nations to implement “coordinated, evidence-based measures for safe travel and to share with WHO experiences and best practices learned.”
During the group’s bi-weekly news webinar, the confirmed global death toll from the coronavirus pandemic surpassed 2 million, according to Johns Hopkins University in the US.

"Health workers are exhausted, health systems are stretched, and we're seeing supplies of oxygen run dangerously low in some countries," said WHO Director-General Tedros Ghebreyesus. "Now is the time we must pull together as a common humanity and rollout vaccines to health workers and those at the highest risk."

The pandemic continues to constitute a Public Health Emergency of International Concern, the committee on COVID-19 again declared.
"The committee strongly encouraged vaccine manufacturers to rapidly provide safety and efficacy data to the WHO for emergency use listing," it said.

The effects of vaccines in reducing transmission are yet unknown and the current availability of vaccines is too limited, the committee added./aa
