Tianjin Cdtec: 2 confirmed cases have no history of leaving Tianjin

But there is an epidemiological link

Zhang Ying, deputy director of the Tianjin Municipal Center for Disease Control and Prevention, introduced that the two cases initially found are currently in the process of circulation and investigation by the cd-control department, including the trajectory investigation of the public security, and no first two cases have a history of travel outside Tianjin.

One confirmed case is a child who has been studying and living in Tianjin's Jinnan District, and the other confirmed case is an adult, whose main activity trajectory involves his work unit and home, and there is no history of travel outside Tianjin in the past 14 days, nor a history of travel in medium- and high-risk areas. However, through a series of subsequent cases, there is still an epidemiological connection between the two people, and the main epidemiological association is the custody class where one confirmed case worked, and the primary school attended by another confirmed case. Epidemiological associations have been made through other cases, so the focus of the next work is on the towns of Xianshuigu and Xinzhuang in Jinnan District, where the first two confirmed cases are located.

Zhang Wenhong said that Omi kerong is not a large flu

How much has been affected by the life and health of the new coronavirus Omilton variant? At the Guanghua Science and Technology Public Welfare Forum held on January 8, Zhang Wenhong, director of the National Center for Infectious Disease Medicine and director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, said that some self-media said that Aomi Kerong caused a "large flu", which lacked scientific basis, and he studied the medical images of Aomi Kerong infected people and believed that this mutant strain "will bite people". A country and region need a strong immune barrier and medical resources to defend itself against the threat of Omicron.

According to reports, Omilon is the natural selection result of the new crown virus under the pressure of human immunity, "it can be said that Omilon won after fighting the immune system." At present, the mutant strain first discovered in South Africa has ravaged the world, resulting in a significant increase in the number of infections in many countries and regions.

Recently, the antibody of the #fourth dose of covid-19 vaccinators increased to five times that of the original #on the hot search.

Last week, Israel began vaccinating specific populations with a fourth dose of covid-19 vaccine. Israeli Prime Minister Bennett said on the 4th local time that according to the preliminary data obtained, the fourth dose of the new crown vaccine is safe and can increase the antibody level in the body of the vaccinator to 5 times before vaccination.

Regarding the fourth dose of the NEW CROWN vaccine, countries have different attitudes.

No.1 British experts do not implement

On January 5, Andrew Pollard, head of the UK's Vaccine Advisory Committee, said the UK should not introduce a fourth dose of COVID-19 vaccine until there is more scientific evidence. In an interview with Britain's Daily Telegraph, Pollard said it was "unsustainable" to provide a vaccine every six months. He said the UK didn't have to block again: "When we do liberalize the epidemic prevention policy, there will be a surge in the number of infected people." "On January 4, local time, the number of new cases in the UK exceeded 200,000 for the first time.

No.2 Thailand, Germany and other countries are implementing the fourth dose of the new crown vaccine

According to thailand network reports, on December 13, 2021, The spokesman of the Thai Epidemic Control Center, Tavisin, held a press conference to explain the content of the meeting of the epidemic control center, Tavisin said that In 2022, Thailand plans to purchase 120 million doses of new crown vaccine, in addition, Prime Minister Prayut also ordered the CDC to make a plan for the purchase of the fourth dose of vaccine. On December 22, Opa, director of the Department of Disease Control of the Ministry of Health of Thailand, revealed after the meeting of the Immunization Subcommittee that the committee meeting approved a proposal to vaccinate medical staff, frontline anti-epidemic workers, and patients with chronic diseases with low immunity for more than 3 months with the 3rd injection of the new crown vaccine.

According to Reuters, German Federal Health Minister Carl Lauterbach said that due to the emergence of the more contagious Omiljung strain, it is necessary to start the fourth dose of new crown vaccination.

No.3 Will There be a fourth dose of covid-19 vaccine in China?

After the completion of the two-dose vaccination work in China, it has entered the stage of intensive injection (third injection).

After the third dose of vaccination began in China, many netizens wondered whether the fourth dose of the new crown vaccine would be implemented. Previously, Zhang Yuntao, vice president of China Biotechnology Co., Ltd., responded at the 5th China Innovative Drug Forum in 2021: "In the future, if the fourth injection is not given, it is necessary to comprehensively give a scientific basis according to the decline of antibodies after the third injection and the changes in the future epidemic." ”
