Delta COVID variant becoming globally dominant, WHO official says

GENEVA (Reuters) – The Delta variant of COVID-19, first identified in India, is becoming the globally dominant variant of the disease, the World Health Organization’s chief scientist said on Friday.

Soumya Swaminathan also voiced disappointment in the failure of CureVac’s vaccine candidate in a trial to meet the WHO’s efficacy standard, in particular as highly transmissible variants boost the need for new, effective shots.

Britain has reported a steep rise in infections with the Delta variant, while Germany’s top public health official predicted it would rapidly become the dominant variant there despite rising vaccination rates.

The Kremlin blamed a surge in COVID-19 cases on reluctance to have vaccinations and “nihilism” after record new infections in Moscow, mostly with the new Delta variant, fanned fears of a third wave.

“The Delta variant is well on its way to becoming the dominant variant globally because of its increased transmissibility,” Swaminathan told a news conference.

Coronavirus variants were cited by CureVac when the German company this week reported its vaccine proved only 47% effective at preventing disease, shy of the WHO’s 50% benchmark.

The company said it documented at least 13 variants circulating within its study population.

Given that similar mRNA vaccines from Pfizer and BioNTech and Moderna posted efficacy rates topping 90%, Swaminathan said the world had been expecting more from CureVac’s candidate.

“Just because it’s another mRNA vaccine, we cannot presume all mRNA vaccines are the same, because each one has a slightly different technology,” Swaminathan said, adding the surprise failure underscored the value of robust clinical trials to test new products.

WHO officials said Africa remains an area of concern, even though it accounts for only around 5% of new global infections and 2% of deaths.

New cases in Namibia, Sierra Leone, Liberia and Rwanda have doubled in the last week, WHO emergencies program head Mike Ryan said, while vaccine access remains miniscule.

“It’s a trajectory that is very, very concerning,” Ryan said. “The brutal reality is that in an era of multiple variants, with increased transmissibility, we have left vast swathes of the population, the vulnerable population of Africa, unprotected by vaccines.”

WHO issues COVID-19 warning to Europe before summer travels

COPENHAGEN (Reuters) – The World Health Organization on Thursday urged Europeans to travel responsibly during the summer holiday season and warned the continent was “by no means out of danger” in the battle against COVID-19 despite a steady decline of infection rates in recent weeks.

“With increasing social gatherings, greater population mobility, and large festivals and sports tournaments taking place in the coming days and weeks, WHO Europe calls for caution,” the WHO’s European head Hans Kluge told a press briefing.

“If you choose to travel, do it responsibly. Be conscious of the risks. Apply common sense and don’t jeopardize hard-earned gains,” Kluge said.

Over the last two months, new COVID-19 cases, deaths and hospitalizations have declined, prompting 36 out of 53 countries in the region to start easing restrictions.

The number of reported COVID-19 infections last week came in at 368,000, a fifth of weekly cases reported during a peak in April this year, Kluge said.

“We should all recognize the progress made across most countries in the region, we must also acknowledge that we are by no means out of danger,” he added.

Kluge said the so-called Delta variant, which was first identified in India, was a matter of concern. This variant, he said, “shows increased transmissibility and some immune escape is poised to take hold in the region while many among vulnerable populations, above the age of 60, remain unprotected.”

Countries should learn from the resurgence in cases seen over the summer last year, even as vaccinations are being rolled out across the region.

With just 30% in the region having received their first dose of vaccines, this would not be enough to prevent another wave of the virus, he said.

WHO classifies India variant as being of global concern

GENEVA (Reuters) -The World Health Organization said on Monday that the B.1.617 variant first identified in India last year was being classified as a variant of global concern.

“We classify it as a variant of concern at a global level,” Maria Van Kerkhove, WHO technical lead on COVID-19, told a briefing. “There is some available information to suggest increased transmissibility.”

Indian coronavirus infections and deaths held close to record daily highs on Monday, increasing calls for the government of Prime Minister Narendra Modi to lock down the world’s second-most populous country.

The WHO has said the predominant lineage of B.1.617 was first identified in India last December, although an earlier version was spotted in October 2020.

The variant has already spread to other countries, and many nations have moved to cut or restrict movements from India.

Van Kerkhove said more information about the variant and its three lineages would be made available on Tuesday.

WHO director-general Tedros Adhanom Ghebreyesus said that the WHO Foundation was launching a “Together for India” appeal to raise funds to purchase oxygen, medicines and protective equipment for health workers.
