AstraZeneca and Russia’s Sputnik V lab to share data in seeking coronavirus vaccine advances

 MOSCOW — The developers of Russia's Sputnik V vaccine will share science with pharmaceutical giant AstraZeneca to explore possible advances against the coronavirus, both sides said Friday, in the first major collaboration of labs that were in the frenzied vaccine hunt.

It also is a further sign of the unprecedented pace of vaccine ­research. Efforts are already underway for improvements and ­second-generation formulas, even before the widespread distribution of the first crop of vaccines from labs in the United States, Europe, China and elsewhere.


The research is aimed at testing new vaccine formulas using ­cold viruses, said a statement by the Anglo-Swedish AstraZeneca, which could work in tandem with Russia’s Gamaleya National Center of Epidemiology and Microbiology, whose Sputnik V uses two injections based on vectors of the common-cold virus, or adenovirus.

The AstraZeneca vaccine, created with the University of Oxford, uses a cold virus that typically infects chimpanzees. That teaches the human immune system to block the novel coronavirus.


AstraZeneca “will soon begin exploring within Russia to understand whether two adenovirus-based vaccines can be successfully combined,” the company said.


Russia said AstraZeneca had agreed to explore using a Sputnik V “component” as part of ­efforts to create an improved vaccine.


For Russia — which trumpeted the partnership in tweets from a Sputnik V account — the deal offers a chance to further promote its flagship vaccine, which is still in Phase 3 trials but became available for health-care workers and others this week in Russia. Initial interest at Moscow clinics for the shots, however, appeared limited as many Russians remained wary of the vaccine.


Russia expected a surge for its Sputnik V vaccine. But many skeptics still stayed away.

The potential collaboration also sets up contrasts as wealthy countries snap up the early supplies of the promising vaccines from U.S.-based Moderna and Pfizer, which worked with Germany’s BioNTech. The AstraZeneca-Oxford vaccine, which is still awaiting regulatory approval, has been promoted by the company as a “vaccine for the world,” with an eye to affordability and global reach.


Russia says it has orders for 1.2 billion doses from more than 40 countries in Asia, Latin America, Africa, Central Asia, India and other regions.

The British government also recently announced that it would begin testing combinations of two technologies, pairing one dose of a viral-vector vaccine like the one from AstraZeneca with a messenger RNA vaccine, the technology used in the Pfizer-BioNTech and Moderna vaccines.

AstraZeneca said in a statement that such combinations “could help unlock synergies in protection and improve vaccine accessibility and could provide an additional approach to help overcome this deadly virus.”


The news comes as setbacks were announced Friday for two Western vaccines, one developed by France’s Sanofi and Britain’s GlaxoSmithKline and the other by Australia’s University of Queensland.


Russian officials said Thursday that Sputnik V’s efficacy is 96.5 percent, compared with 70 percent for the AstraZeneca-Oxford vaccine.


The British medical journal the Lancet on Tuesday published a peer-reviewed paper on the AstraZeneca vaccine, but questions lingered about how well it worked in people over 55 and about results showing better outcomes with an initial half-dose. Full scientific data on Sputnik V has not been released, but Russia has promised to provide access to all data to any country interested in the vaccine.


“We offered @AstraZeneca to use one of our vectors so they can also have two vectors in their vaccine. AZ confirmed,” the developers of Sputnik V tweeted Friday.


“The new chapter of vaccine cooperation has started today,” another tweet announced. “We made an offer and AstraZeneca accepted it. It all happened here on Twitter!”


Russia’s decision to register and roll out the vaccine before Phase 3 trials were completed was criticized as reckless by some Western scientists. But Russian officials have grown increasingly hostile and defensive at what they see as Western attacks designed to discredit Russia’s vaccine for commercial reasons.


Igor Konashenkov, a Russian military spokesman, on Friday attacked what he called a foreign-funded “information sabotage” effort against Sputnik V from inside and outside Russia.


Foreign Minister Sergei Lavrov said Thursday that the United States and its allies were trying to exploit the pandemic, creating a global vaccine race.


Russia had called for global cooperation to defeat the threat, he said, “but unfortunately, a number of countries, primarily the Americans and their allies, are trying to use this situation in their geopolitical interests, putting their selfish interests above those of all humanity.”


AstraZeneca vaccine details published in Lancet, but questions remain

Kremlin spokesman Dmitry Peskov on Friday denounced unspecified “dirty tricks . . . to discredit our vaccine” and told journalists that “there should not be any rivalry on the vaccine market.”

Sputnik V’s developers on Friday also offered to share the Russian vaccine with France’s Sanofi and Britain’s GlaxoSmithKline to boost their vaccine’s efficacy.


Sanofi and GSK announced Friday that their vaccine would be delayed until the end of next year after their trial found a low immune response in older adults.


“#Sputnik V is willing to share its technology with Sanofi and GSK to help in developing their next vaccine,” the Russian Direct Investment Fund, backer of Sputnik V, tweeted. “A partnership of different producers is the way of the future.”


So far, 150,000 Russians have been vaccinated with the Sputnik V vaccine, Gamaleya Center Director Alexander Gintsburg said Thursday. Only front-line health workers and teachers qualify to get the shot in mass vaccinations at government health clinics that opened this week. The Russian military is also offering vaccines to service members.


Polling in Russia shows that many Russians remain skeptical about being vaccinated, with anti-vaccine conspiracy theories circulating online, and that some Russians are convinced the coronavirus does not exist. Any collaboration with a major Western drug company could boost Russian government efforts to encourage Russians to get vaccinated.


Clinical trials of a second Russian vaccine, developed by the Vector Center, began Friday.


The global price of the Sputnik V vaccine has been set at about $20 for two shots. Russian developers say the vaccine can be stored at about 18 degrees, making it easier to store and transport than the Pfizer-BioNTech vaccine, which must be kept at ultracold temperatures. The AstraZeneca-Oxford vaccine, however, can be stored long term at ordinary refrigerator temperatures.

China just stunned the world with its step-up on climate action

 China’s President Xi Jinping surprised the global community recently by committing his country to net-zero emissions by 2060. Prior to this announcement, the prospect of becoming “carbon neutral” barely rated a mention in China’s national policies.

October 8, 2020

China currently accounts for about 28% of global carbon emissions – double the US contribution and three times the European Union’s. Meeting the pledge will demand a deep transition of not just China’s energy system, but its entire economy.

Importantly, China’s use of coal, oil and gas must be slashed, and its industrial production stripped of emissions. This will affect demand for Australia’s exports in coming decades.

It remains to be seen whether China’s climate promise is genuine, or simply a ploy to win international favour. But it puts pressure on many other nations – not least Australia – to follow.

It remains to be seen whether China will deliver on its climate pledge. Da qing/AP

Goodbye, fossil fuels

Coal is currently used to generate about 60% of China’s electricity. Coal must be phased out for China to meet its climate target, unless technologies such as carbon-capture and storage become commercially viable.

Natural gas is increasingly used in China for heating and transport, as an alternative to coal and petrol. To achieve carbon neutrality, China must dramatically reduce its gas use.

Electric vehicles and hydrogen fuel-cell vehicles must also come to dominate road transport - currently they account for less than 2% of the total fleet.

China must also slash the production of carbon-intensive steel, cement and chemicals, unless they can be powered by renewable electricity or zero-emissions hydrogen. One report suggests meeting the target will mean most of China’s steel is produced using recycled steel, in a process powered by renewable electricity.

Modelling in that report suggests China’s use of iron ore – and the coking coal required to process it into steel – will decrease by 75%. The implications for Australia’s mining industry would be huge; around 80% of our iron ore is exported to China.

It is critically important for Australian industries and policymakers to assess the seriousness of China’s pledge and the likelihood it will be delivered. Investment plans for large mining projects should then be reconsidered accordingly.

Conversely, China’s path towards a carbon neutral economy may open up new export opportunities for Australia, such as “green” hydrogen.

A renewables revolution

Solar and wind currently account for 10% of China’s total power generation. For China to meet the net-zero goal, renewable energy generation would have to ramp up dramatically. This is needed for two reasons: to replace the lost coal-fired power capacity, and to provide the larger electricity needs of transport and heavy industry.

Two factors are likely to reduce energy demand in China in coming years. First, energy efficiency in the building, transport and manufacturing sectors is likely to improve. Second, the economy is moving away from energy- and pollution-intensive production, towards an economy based on services and digital technologies.

It’s in China’s interests to take greater action on climate change. Developing renewable energy helps China build new “green” export industries, secure its energy supplies and improve air and water quality.

The global picture

It’s worth considering what factors may have motivated China’s announcement, beyond the desire to do good for the climate.

In recent years, China has been viewed with increasing hostility on the world stage, especially by Western nations. Some commentators have suggested China’s climate pledge is a bid to improve its global image.

The pledge also gives China the high ground over a major antagonist, the US, which under President Donald Trump has walked away from its international obligations on climate action. China’s pledge follows similar ones by the European Union, New Zealand, California and others. It sets an example for other developing nations to follow, and puts pressure on Australia to do the same.

The European Union has also been urging China to take stronger climate action. The fact Xi made the net-zero pledge at a United Nations meeting suggests it was largely targeted at an international, rather than Chinese, audience.

However, the international community will judge China’s pledge on how quickly it can implement specific, measurable short- and mid-term targets for net-zero emissions, and whether it has the policies in place to ensure the goal is delivered by 2060.

Much is resting on China’s next Five Year Plan – a policy blueprint created every five years to steer the economy towards various priorities. The latest plan, covering 2021–25, is being developed. It will be examined closely for measures such as phasing out coal and more ambitious targets for renewables.

Also key is whether the recent rebound of China’s carbon emissions – following a fall from 2013 to 2016 – can be reversed.

Wriggle room

The 2060 commitment is bold, but China may look to leave itself wriggle room in several ways.

First, Xi declared in his speech that China will “aim to” achieve carbon neutrality, leaving open the option his nation may not meet the target.

Second, the Paris Agreement states that developed nations should provide financial resources and technological support to help developing countries reduce their emissions. China may make its delivery of the pledge conditional on this support.

Third, China may seek to game the way carbon neutrality is measured – for example, by insisting it excludes carbon emissions “embodied” in imports and exports. This move is quite likely, given exports account for a significant share of China’s total greenhouse gas emissions.

So for the time being, the world is holding its applause for China’s commitment to carbon neutrality. Like every nation, China will be judged not on its climate promises, but on its delivery.

Tiananmen massacre ‘erased from Hong Kong textbooks’

 Suppression of 1989 events is latest crackdown on pro-democracy movement


The 1989 Tiananmen massacre and crackdown are set to be erased from Hong Kong school books, as Beijing seeks to crush the city’s pro-democracy movement

Hong Kong Watch responds to plans by Beijing to suppress information regarding the Tiananmen Square massacre in Hong Kong textbooks

20 August 2020

According to a report in The Times, the Chinese Communist Party has removed mention of the 1989 Tiananmen Square massacre from Hong Kong school textbooks submitted for government review.

Three out of five of the text books make no mention of the massacre itself, while the other two have removed significant details including the number of protestors who were killed and the motives behind their discontent.

This development follows the introduction of the National Security Law on June 30th, which requires national security education be introduced into the Hong Kong curriculum. Since the introduction of the law, the Chinese Government has set up a national security centre in Shenzhen for students and teachers who are deemed unpatriotic to be ‘re-educated’, banned the singing of protest anthems in the classroom, and encouraged universities to fire pro-democracy academics, including Benny Tai, one of the organisers of the Umbrella Movement protests in 2014.

Commenting on reports of the censorship of textbooks, Hong Kong Watch’s Chair and co-founder Benedict Rogers, said:

“This is a deeply disturbing development which signposts the death of academic freedom in Hong Kong. It is increasingly clear that the Chinese Communist Party plans not only to silence dissent on the streets but also in the classroom by censoring textbooks, purging academics, and sending students for patriotic ‘re-education’.

The international community must stand in defence of academic freedom in Hong Kong and act to prevent the further destruction of Hong Kong's autonomy and openness, which has already been so severely undermined by recent events. Hong Kong is rapidly coming under the direct control of the Chinese Communist Party, its surveillance state and draconian punishments, which threaten the future for students' freedom of intellectual inquiry and expression, and the free world must stand against that and with those who cherish Hong Kong's fundamental freedoms."

China Launches Beidou, Its Own Version of GPS

 China places the final Beidou navigation system satellite into orbit


The stable signals of 13 Beidou satellites can be searched by using the test software. The software displays 13 US GPS satellites, 6 Russian GLONASS satellites and 1 Japanese positioning satellite. Shanghai, China, June 25, 2020.

The final satellite needed to complete China’s own navigation and positioning satellite system has passed final on-orbit tests. The completed independent system provides military and commercial value while also facilitating new technologies and services.

The Beidou was launched on a Long March 3B rocket from the Xichang Satellite Launch Center in a hilly region of Sichuan province at 01:43 UTC on Tuesday, 23 June. The satellite was sent into a geosynchronous transfer orbit before entering an orbital slot approximately 35,786 kilometers in altitude which keeps it at a fixed point above the Earth.

Like GPS, the main, initial motivation for Beidou was military. The People’s Liberation Army did not want to be dependent on GPS for accurate positioning data of military units and weapons guidance, as the U.S. Air Force could switch off open GPS signals in the event of conflict. 

As with GPS, Beidou also provides and facilitates a range of civilian and commercial services and activities, with an output value of $48.5 billion in 2019.

Twenty four satellites in medium Earth orbits (at around 21,500 kilometers above the Earth) provide positioning, navigation and timing (PNT) services. The satellites use rubidium and hydrogen atomic clocks for highly-accurate timing that allows precise measurement of speed and location.

Additionally, thanks to a number of satellites in geosynchronous orbits, Beidou provides a short messaging service through which 120-character messages can be sent to other Beidou receivers. Beidou also aids international search and rescue services. Vessels at sea will be able to seek help from nearby ships in case of emergency despite no cellphone signal.

The Beidou satellite network is also testing inter-satellite links, removing reliance on ground stations for communications across the system.

Beidou joins the United States’ GPS and Russia’s GLONASS in providing global PNT services, with Europe’s Galileo soon to follow. These are all compatible and interoperable, meaning users can draw services from all of these to improve accuracy.

“The BeiDou-3 constellation transmits a civil signal that was designed to be interoperable with civil signals broadcast by Galileo, GPS III, and a future version of GLONASS. This means that civil users around the world will eventually be getting the same signal from more than 100 satellites across all these different constellations, greatly increasing availability, accuracy, and resilience,” says Brian Weeden, Director of Program Planning for Secure World Foundation

“This common signal is the result of international negotiations that have been going on since the mid-2000s within the International Committee of GNSS (ICG).”

The rollout of Beidou has taken two decades. The first Beidou satellites were launched in 2000, providing coverage to China. Second generation Beidou-2 satellites provided coverage for the Asia-Pacific region starting in 2012. Deployment of Beidou-3 satellites began in 2015, with Tuesday’s launch being the 30th such satellite. 

But this is far from the end of the line. China wants to establish a ‘ubiquitous, integrated and intelligent and comprehensive’ national PNT system, with Beidou as its core, by 2035, according to a white paper.

Chinese aerospace firms are also planning satellite constellations in low Earth orbit to augment the Beidou signal, improving accuracy while facilitating high-speed data transmission. Geely, an automotive giant, is now also planning its own constellation to improve accuracy for autonomous driving.

Although the space segment is complete, China still has work to do on the ground to make full use of Beidou, according to Weeden.

“It's not just enough to launch the satellites; you also have to roll out the ground terminals and get them integrated into everything you want to make use of the system. Doing so is often much harder and takes much longer than putting up the satellites. 

“So, for the Chinese military to make use of the military signals offered by BeiDou-3, they need to install compatible receivers into every plane, tank, ship, bomb, and backpack. That will take a lot of time and effort,” Weeden states.

With the rollout of Beidou satellites complete, inhabitants downrange of Xichang will be spared any further disruption and possible harm. Long March 3B launches of Beidou satellites frequently see spent rocket stages fall near or on inhabited areas. Eighteen such launches have been carried out since 2018.

The areas calculated to be under threat from falling boosters were evacuated ahead of time for safety. Warnings about residual toxic hypergolic propellant were also issued. But close calls and damage to property were all too common.
