“More vaccines are being developed, approved and produced. There will be enough for everyone," WHO Director General Tedros Adhanom Ghebreyesus told reporters in Geneva.

"But for now, vaccines are a limited resource. We must use them as effectively and as fairly as we can. If we do that, lives will be saved," the UN News quoted him as saying.

New ‘window of opportunity’

Saturday will mark a year since the UN health agency first sounded the alarm over the new coronavirus disease, declaring it a public health emergency of international concern.

Covid cases worldwide have surpassed 102 million, and Tedros said more cases were reported in the past two weeks than during the first six months of the pandemic.

“A year ago, I said the world had a ‘window of opportunity’ to prevent widespread transmission of this new virus. Some countries heeded that call, some did not," he said.

“Now, vaccines are giving us another window of opportunity to bring the pandemic under control. We must not squander it," the WHO head added.

Turning point in history

The pandemic has exposed and exploited inequalities, the WHO chief noted. “There is now the real danger that the very tools that could help to end the pandemic – vaccines – may exacerbate those same inequalities."

“Vaccine nationalism might serve short-term political goals. But it’s ultimately short-sighted and self-defeating," he said.

Tedros reiterated that the pandemic will not be over until it ends everywhere.

“The world has come to a critical turning point in the pandemic," he said. “But it’s also a turning point in history: faced with a common crisis, can nations come together in a common approach?”

He urged governments to vaccinate health workers and older people, and to share excess doses with the COVAX Facility, the global mechanism working to ensure equitable access and distribution, “so other countries can do the same”.

EU export ban ‘not helpful’

WHO has expressed concern over new European Union (EU) measures to control export of Covid vaccines, announced on Friday.

This is “a very worrying trend”, said Dr Mariângela Simão, the agency’s Assistant Director-General for Drug Access, Vaccines and Pharmaceuticals, responding to a poser.

She explained that medicines and vaccines can contain components that come from across the world.

“Let’s say it is not helpful to have any country at this stage putting export bans or barriers that will not allow for the free movement of the necessary ingredients that will make vaccines, diagnostics and other medicines available to all the world," she said.
