Director-General of the World Health Organization Tedros Adhanom Ghebreyesus on Wednesday called for joint efforts to ensure peace and provide sufficient space for the completion of the mass polio vaccination campaign for children in the Gaza Strip. Amid the continuing conflict, WHO and its partners launched the second round of a polio vaccination campaign on Monday, aiming to immunize over half a million children.
At a press conference held at the WHO headquarters in Geneva, Tedros briefed the media on the latest situation in Gaza after the WHO and its partners began the second round of its vaccine campaign targeting more than half a million children on Monday.
"A minimum of two doses of vaccine are needed to interrupt poliovirus transmission. This will only be achieved if at least 90 percent of all eligible children are vaccinated in all communities and neighborhoods. In this round, children will also receive vitamin A to help boost their immunity," he said.
Tedros added that nearly 157,000 children had already received a second dose of the polio vaccine in central Gaza in the first two days of the latest vaccination round.
The first round was implemented across three phases in early September, vaccinating more than 559,000 children, after Gaza recorded the first case of poliovirus infection in 25 years in August.
The WHO chief also urged Israel to grant access to northern Gaza, where increasing levels of violence have blocked humanitarian missions from delivering critical food and medical supplies.
"Escalating violence in the north of Gaza has blocked humanitarian missions from reaching people with food and medical supplies. In the first half of October, only one UN mission out of 54 to northern Gaza was successfully facilitated. The rest were denied, cancelled or impeded. Under international humanitarian law, all actors have a duty to ensure health care is protected, and not attacked," Tedros said.

China’s first intelligent field plant phenotype precision identification platform went into operation recently in Sanya City, south China’s Hainan Province, which is a milestone in the country’s development of intelligent breeding.
The phenotype of a plant is a term used to describe observable characteristics of the plant, such as its appearance, and some inherent physiological characteristics, such as resistance to drought and diseases.
In an experimental field of the National Nanfan Research Institute of the Chinese Academy of Agricultural Sciences, a large piece of equipment is moving across the field. The equipment, called the field plant phenotype precision identification platform, can move according to the preset track and can be remotely controlled. While moving, the equipment can scan the plants with its six sensors, just like a CT machine for plants.
"The ultimate goal is to achieve high-throughput, large-scale, efficient and precise collection of germplasm resources, which can be four to five times higher than the efficiency of the traditional manual collection," said Jin Xiuliang, a researcher at the institute.
Although the equipment looks simple from the outside, it contains six high-precision image acquisition devices such as multi-spectral, thermal infrared, and chlorophyll fluorescence devices. Data can be collected at fixed times and points according to experimental needs, and the collection of a germplasm material can be completed within 30 seconds.
After the data collected through this platform is transmitted to the data analysis center, researchers can more quickly and accurately screen out germplasm resources with excellent traits, laying the foundation for subsequent crop breeding.
"The plant phenotype identification facility at the National Nanfan Research Institute is a milestone in the field of crop science in China. It can greatly enhance the independent innovation capabilities of germplasm innovation, gene mining, and variety breeding, and enhance the international competitiveness of China's seed industry," said Li Huihui, vice president of the institute.
