As nations like the United States prepare for a summer of hugs, gatherings and other activities safe for the vaccinated, nations still scrambling for shots are seeing some of their worst outbreaks.
The W.H.O. said it will label variants with Greek letters instead of numbers. Scientists hope the change will end the practice of referring to the mutations by the places they were detected.
A new, more transmissible variant could devastate countries without vaccines.
Countries should be getting vaccines based on their needs, not their population.
Vaccinating the world is possible. The United States should lead the way.
Researchers urge an open mind, saying lack of evidence leaves theories of natural spillover and laboratory leak both viable.

A biotech company, that has spent 11 years researching supplements to increase human longevity, plans to launch its supplements later this year. Longevica says it has attracted a total of $13 million from investors including, Alexander Chikunov, a longevity investor, who is also president of the company.
Longevica says it created a biotechnology platform for longevity after researching the life-span of laboratory mice. It now aims to produce medicines, dietary supplements, and food products.
The longevity space is a growing sector for tech startups. Google backed the launch of Calico in the space. Late last year Humanity Inc. raised $2.5 million in a round led by Boston fund One Way Ventures for its longevity company that will leverage AI to maximize people’s healthspan.
Longevica’s CEO Aynar Abdrakhmanov, backing up his company’s aim to tap the desire for people to live longer, said: “According to the WHO, by 2050, 2 billion people will be 60+ years old. By 2026, the sales of services and products for this audience will be around $27 trillion… By comparison, it was only $17 trillion in 2019.”
According to CB Insights, life-extension startups raised a record total of $800 million in 2018 alone. And there are some high-profile investors in the space.
PayPal co-founder Peter Thiel invested in Unity Biotechnology, which is developing drugs to treat diseases that accompany aging, has also raised significant funding. And Ethereum founder Vitalik Buterin invested $2.4 million worth of Ether into the nonprofit SENS Research foundation, where famed longevity research Aubrey de Grey is chief science officer, to develop rejuvenation biotechnologies.
Longevica is basing its platform on the work of scientist Alexey Ryazanov, who holds 10 US patents in the space, and a long-time researcher into the regulation of protein biosynthesis cells.
Chikunov said: “I gathered scientists known in this field to discuss their approaches to the problem. Then Alexey Ryazanov proposed the innovative idea of large-scale screening of all known pharmacological substances on long-lived mice in order to find those that prolong life.”
Under the leadership of Ryazanov, Longevica says it used 20,000 long-lived female mice and 1,033 drugs representing compounds from 62 pharmacological classes, to find five substances that statistically significantly increased longevity by 16-22%: Inulin, Pentetic Acid, Clofibrate, Proscillaridin A, D-Valine.
From this work, they formed a view about the elimination of certain heavy metals from the body and improve the body’s ability to remove toxins.
The president should keep his promise on vaccine patents.
Covid fuels the current virus pandemic, but the world is full of flu viruses waiting in the wings. And they keep changing unpredictably.
A scientific mission to China proposed further study for a number of topics. Critics and the director of the W.H.O. have weighed in as well.
Did Covid-19 come from animal markets? It’s unclear. Did it emerge from a lab? Also unclear. Here’s what a new W.H.O. report says — including questions that the agency’s own chief raised about the findings.
The European Medicines Agency will add a label to the shot, warning doctors to watch for possible rare, abnormal bleeding in the brain. But as the pandemic worsens in Europe, officials are desperate to fully resume its use.
And yes, there could soon be another pandemic.
For months John Magufuli railed against masks, social distancing and vaccines. Now rumors are circulating that he’s critically ill with Covid-19.
Vaccines and critical-care beds are in short supply. Yet President Jair Bolsonaro is railing against social distancing and calling an experimental treatment from Israel “miraculous.”
Those who still suspect the outbreak in China may have been caused by a lab leak or accident are pressing for an independent investigation.
B.1.351 may sound sweet to a molecular epidemiologist, but what’s the alternative, other than stigmatizing geographical names?
The coronavirus threat is global. So is the remedy.
Hundreds of thousands of AstraZeneca doses are sitting unopened as many Germans reject the vaccine over fears it is “second-class” compared to the one developed by BioNTech and Pfizer.
An operation to supply billions of coronavirus vaccine doses to poorer countries has started. But as rich countries buy most of the available supply, stark inequalities remain.
A half-million doses arrived this month in Afghanistan, where many insist the virus isn’t real and vaccines aren’t needed. Those who want the vaccine fear that only the well-connected will receive it.

Health officials promised rapid delivery of vaccines and other epidemic-fighting measures after confirming seven cases in the country’s southeast.

Experts with the global health agency endorsed critical parts of Beijing’s narrative, even some parts that independent scientists question.
They, too, work, and they can help fill shortages everywhere.
The change aligns the organization with the guidance from the U.S. Centers for Disease Control and Prevention.
Rich countries are cornering the market on coronavirus vaccines, leaving poorer regions as potential breeding grounds for variants, like one found in South Africa, that could make vaccines less effective.
Practical pandemic guidance is still a huge problem.
The W.H.O. and the C.D.C. provide differing views, and experts partly blame a lack of data because expectant mothers have been excluded from clinical trials.
Multibillion-dollar contracts give drug makers liability shields, patent ownership and leeway on delivery dates and pricing — and promises that much of it will not be made public.
