China's homegrown 9-valent HPV vaccine expected to boost immunisation coverage
A girl receives a human papillomavirus (HPV) vaccine at the provincial Maternity and Child Healthcare Hospital in Wuhan, central China's Hubei Province, May 18, 2020. – Xinhua photo BEIJING (June 8): China's drug regulator has approved the country's first domestically developed 9-valent human papillomavirus (HPV) vaccine, ending over a decade of foreign dominance in the market. The vaccine, Cecolin 9, has been included on a list of approved medical products that was made public by the National Medical Products Administration on Wednesday. 'The approval of Cecolin 9 not only offers more vaccination options for eligible women in China, but is also expected to improve vaccine accessibility and coverage, reducing the risk of cervical cancer further,' said Zhang Jun, dean of the School of Public Health at Xiamen University and a leading member of the vaccine development team. HPV vaccines are commonly used to prevent cervical cancer in women, as well as genital cancers and warts in both men and women. Cecolin 9, which targets nine HPV strains, was developed by Xiamen University, the Xiang An Biomedicine Laboratory and Xiamen Innovax Biotech Co., Ltd, marking a breakthrough in China's ability to produce high-valency HPV vaccines independently. China is now the second country – after the United States – capable of supplying 9-valent HPV vaccines. Compared to bivalent HPV vaccines, which are effective against two high-risk genotypes (HPV 16 and 18), 9-valent HPV vaccines protect against an additional five high-risk genotypes (HPV 31, 33, 45, 52 and 58) and two low-risk genotypes (HPV 6 and 11), and provide better protection against cervical cancer. Over 18 years of research, scientists overcame major technical challenges in producing virus-like particles (VLPs) from multiple HPV types using an E. coli platform, and completed crucial clinical trial validation processes. Five related clinical trials have been conducted across China since 2019, and the vaccine has demonstrated a favorable safety profile and a strong immune response, comparable to those of similar international products. Statistics show that globally, approximately 700,000 cancer cases each year are associated with HPV, including an estimated 530,000 cases of cervical cancer. Vaccination is up to 94 percent effective in preventing HPV infection. In 2020, the World Health Organisation (WHO) launched a global strategy to accelerate the elimination of cervical cancer, aiming for 90 percent of girls to be fully vaccinated against HPV by the age of 15 by 2030. In alignment with the WHO strategy, China's National Health Commission launched a cervical cancer elimination action plan for the 2022-2030 period, urging the expansion of HPV vaccination coverage nationwide. 9-valent human papillomavirus China hpv vaccine

Youths 'can bridge AI gap between Global South, North'
Youths 'can bridge AI gap between Global South, North' Boao Forum for Asia secretary general Zhang Jun, right, says artificial intelligence development gaps will fuel further digital divisions. Photo: RTHK Participants at the forum at the Convention and Exhibition Centre said access and skills for youths and young entrepreneurs posed challenges for their economies. Photo: RTHK Boao Forum for Asia secretary general Zhang Jun said on Friday youths play a key role in bridging the artificial intelligence development gap between the Global South and Global North. He made the remarks as the International Science, Technology and Innovation Forum of the Boao Forum made its debut in Hong Kong, with previous editions held in Macau, Zhuhai and Guangzhou. Speaking at a roundtable session, Zhang, who served as a permanent representative of China to the United Nations, said the digital divide, which includes AI development gaps, will further weigh on global fragmentation. He called on youths to help forge global collaboration to tackle such challenges. "Youths have a key role... in really trust-building, partnership-building, which is also badly needed in today's world, because we are more divided than [at any time] after the end of the Second World War. "And we are living in a world which is becoming very much dangerous because of the failure of the international governance system, including the United Nations," Zhang said. Many of the forum's participants pointed out challenges encountered during their countries' own digital transformation, especially with access and skills for youths and young entrepreneurs. Many said it's essential to ramp up digital literacy training and partnerships between nations. Mimala Chanthasone, an official of the Institute of Foreign Affairs in Laos, cited the China-Laos AI Innovation Cooperation Centre as an example. Launched in February, she said the centre marks the first China-Asean AI innovation cooperation. Conrad Ho, a member of the Youth Development Commission, called for more efforts to be made to address the employability gap created by the emergence of AI technology. "The post-AI world presents many challenges and also opportunities, including how youth might gain more senior-level skills as AI reduces the demand for entry-level and middle-management roles," he said. "I think as AI unlocks more capacity, we're going to transition from [having more] large corporations to smaller ventures, one-person teams, smaller teams that can still create very massive value. "And yet for all these companies, for them to be successful, the founders still need to have the critical hard and soft skills that they need to learn." The two-day innovation forum ends on Saturday.

‘Prepare for the worst': China minds, on guard against US punches, stress need for talks
Trade upheaval resulting from the tariff war ignited by US President Donald Trump last month appears to have cast a long-lasting impact on the mindset of Chinese policy influencers, with thoughts of 'preparing for the worst' spreading at a forum in Beijing on Thursday. Advertisement With exporters rushing to secure US-bound shipments during the 90-day truce period, many ex-official and policy advisers have urged the government to guard against any future barrage of American punches, and to also rally the support of major trading partners and forge stronger relations with Global South nations. Zhang Jun, former Chinese ambassador to the United Nations, called the China-US talks in Geneva a positive development, but he explicitly warned that the tariff war – with Washington's tariff levies having risen as high as 145 per cent and effectively bringing bilateral trade flow to a halt before the truce – has already inflicted deep and lasting harm. 'The situation could evolve further, so we need to remain highly vigilant to prevent global order from slipping into chaos and to avoid greater instability on a global scale,' he said at a forum held by Centre for China and Globalisation, a Beijing-based think tank. He underscored the necessity of reforming international institutions – a complex and time-consuming endeavour – and called for stronger regional cooperation. Advertisement 'If the current international institutions continue to fail to function, there will definitely be a vacuum, and some troublemakers would make use of that vacuum and to create more problems,' he said. 'I am not pessimistic, but we have to prepare for the worst and try our best to prevent the worst from happening.'

World's first three-satellite constellation in Earth-moon region established by China
The world's first three-satellite constellation on the distant retrograde orbit (DRO) of the Earth-Moon system has been successfully established by Chinese scientists. The development lays a foundation for the exploration and utilization of space, and for future crewed deep-space exploration. The DRO is a unique type of orbit, while the Earth-moon space refers to the region extending outward from near-Earth and near-lunar orbits, reaching a distance of up to 2 million kilometers from by scientists of the Chinese Academy of Sciences (CAS), DRO-A and DRO-B satellites have established inter-satellite measurement and communication links with DRO-L, a previously launched near-Earth orbit satellite. The achievement was disclosed at a symposium on Earth-moon space DRO exploration in Beijing on have revealed that in Earth-moon space, DRO is characterized by a prograde motion around Earth and a retrograde motion around the which provides a highly stable orbit where spacecraft require little fuel to enter and stay, also serves as a natural space hub connecting Earth, the moon, and deep offers support for space science exploration, the deployment of space infrastructure, and crewed deep-space missions. Currently, the DRO-A satellite stays in DRO, while the DRO-B satellite operates in Earth-moon space maneuver orbits, according to the Technology and Engineering Center for Space Utilization (CSU). Zhang Jun, a senior engineer at the CAS' Innovation Academy for Microsatellites, revealed that the satellites ultimately succeeded in entering their designated orbit, demonstrating China's breakthroughs in deep-space fault recovery and autonomous navigation technologies. Zhang stated that this achievement highlights the satellite team's flexibility and adaptability in complex missions and paved the way for low-cost deep-space also revealed that the project achieved the world's first spacecraft entry into DRO with low energy consumption. Through innovative design, the team completed a lunar transfer and DRO entry by using just one-fifth of the fuel usually required. Scientists revealed that the program would support China's future lunar exploration mission, including providing space-based inter-satellite measurement for rapid orbit determination and autonomous navigation services for lunar exploration mission orbiters, and supply high-precision time signals for lunar surface facilities, reported Global Times. Zhang highlighted that by using three hours of in-orbit inter-satellite measurement data, the team achieved an orbit determination precision level that would typically require two days of ground-based tracking. This advancement has significantly reduced operational costs and improved the efficiency of spacecraft in the Earth-moon space. Later, Chinese scientists will continue investigating the complex and diverse orbits in the Earth-moon space, and study the laws of the lunar space environment. With the long-term stability of DRO, scientists will carry out fundamental scientific research in such fields as quantum mechanics and atomic physics.
