Vaccine effectiveness against severe COVID drops slightly, still ‘significant protection’-WHO

COVID-19 vaccines appear to have become slightly less effective in preventing severe disease and death but do provide “significant protection”, the World Health Organization (WHO) said on Tuesday, Reuters reported.

According the report the Omicron variant first detected in South Africa and Hong Kong last month has now been reported by 77 countries and is probably present in most worldwide, but should not be dismissed as “mild”, WHO Director-General Tedros Adhanom Ghebreyesus said.

“Omicron is spreading at a rate we have not seen with any previous variant,” Tedros told an online briefing. “Even if Omicron does cause less severe disease, the sheer number of cases could once again overwhelm unprepared health systems.”

“Evolving evidence suggests a small decline in the effectiveness of vaccines against severe disease and death, and a decline in preventing mild disease or infection,” he said without giving specifics.

Pfizer-BioNTech’s COVID-19 vaccine has been less effective in South Africa at keeping people infected with the virus out of hospital since the Omicron variant emerged last month, a real-world study published on Tuesday showed, read the report.

Mike Ryan, WHO’s emergencies director, said that the vaccines are not failing and do provide significant protection against severe disease and death.

“The question is how much protection are the current vaccines that we are using, which are currently life-saving against all the variants, and to what extent do we lose any protection against severe illness and death against Omicron. The data is pointing towards there being significant protection.”

Ryan said the peak of this wave of infections remains “a number of weeks” away given the very rapid spread of the Omicron variant, which has outpaced the dominant global strain Delta.

According to Reuters vaccine booster shots can play a role in curbing the spread of COVID-19 as long as people most in need of protection also get access to jabs, Tedros said.

“It’s a question of prioritisation. The order matters. Giving boosters to groups at low risk of severe disease or death simply endangers the lives of those at high risk who are still waiting for their primary doses because of supply constraints.

“On the other hand, giving additional doses to people at high risk can save more lives than giving primary doses to those at low risk,” he said.

Tedros noted that the emergence of Omicron had prompted some countries to roll out COVID-19 booster programmes for their entire adult populations, even while researchers lack evidence for the efficacy of boosters against this variant.

“WHO is concerned that such programmes will repeat the vaccine hoarding we saw this year, and exacerbate inequity,” he said.

WHO declares end to COVID global health emergency

The World Health Organization said Friday that COVID-19 no longer qualifies as a global emergency, marking a symbolic end to the devastating coronavirus pandemic that triggered once-unthinkable lockdowns, upended economies and killed millions of people worldwide.

The announcement, made more than three years after WHO declared the coronavirus an international crisis, offers some relief, if not an ending, to a pandemic that stirred fear and suspicion, hand-wringing and finger-pointing across the globe, AP reported. 

The U.N. health agency’s officials said that even though the emergency phase was over, the pandemic hasn’t finished, noting recent spikes in cases in Southeast Asia and the Middle East.

WHO says thousands of people are still dying from the virus every week, and millions of others are suffering from debilitating, long-term effects.

“It’s with great hope that I declare COVID-19 over as a global health emergency,” WHO Director-General Tedros Adhanom Ghebreyesus said.

“That does not mean COVID-19 is over as a global health threat,” he said, warning that new variants could yet emerge. Tedros noted that while the official COVID-19 death toll was 7 million, the real figure was estimated to be at least 20 million.

Tedros said the pandemic had been on a downward trend for more than a year, acknowledging that most countries have already returned to life before COVID-19.

He bemoaned the damage that COVID-19 had done to the global community, saying the pandemic had shattered businesses, exacerbated political divisions, led to the spread of misinformation and plunged millions into poverty.

When the U.N. health agency first declared the coronavirus to be an international crisis on Jan. 30, 2020, it hadn’t yet been named COVID-19 and there were no major outbreaks beyond China.

More than three years later, the virus has caused an estimated 764 million cases globally and about 5 billion people have received at least one dose of vaccine.

In the U.S., the public health emergency declaration made regarding COVID-19 is set to expire on May 11, when wide-ranging measures to support the pandemic response, including vaccine mandates, will end. Many other countries, including Germany, France and Britain, dropped most of their provisions against the pandemic last year.

When Tedros declared COVID-19 to be an emergency in 2020, he said his greatest fear was the virus’ potential to spread in countries with weak health systems.

Most recently, WHO has struggled to investigate the origins of the coronavirus, a challenging scientific endeavor that has also become politically fraught.

China says 200 million treated, pandemic ‘decisively’ beaten

China says more than 200 million of its citizens have been diagnosed and treated for COVID-19 since it lifted strict containment measures beginning in November.

With 800,000 of the most critically ill patients having recovered, China has “decisively beaten” the pandemic, according to notes from a meeting of the ruling Communist Party’s all-powerful Politburo Standing Committee presided over by President and party leader Xi Jinping, AP reported. 

China enforced some of the world’s most draconian lockdowns, quarantines and travel restrictions and still faces questions about the origins of the virus that was first detected in the central Chinese city of Wuhan in late 2019. Heavy-handed enforcement prompted rare anti-government protests and took a heavy toll on the world’s second-largest economy.

The official Xinhua News Agency quoted Xi as saying that policies to control the outbreak had been “entirely correct.” The abrupt lifting in November and December of the “zero COVID” policy that had sought to eliminate all cases of the virus led to a surge in infections that temporarily overwhelmed hospitals.

Case numbers have since peaked and life has largely returned to normal, although international travel in and out of China has yet to return to pre-pandemic levels.

China is now transitioning to a post-pandemic stage after a fight against the outbreak that was “extraordinary in the extreme,” Xinhua said.

The government will continue to “optimize and adjust prevention and control policies and measures according to the times and situations with a strong historical responsibility and strong strategic determination,” Xinhua said.
