Progress has been made in many countries by the intensive release of data from clinical trials of the new crown vaccine.

Medicine Network Monthly New Crown outbreak in the global multi-point people are looking for a safe and effective new crown virus vaccineRecent advances in the development of new coronavirus vaccines in several countries have been intensively published in relevant medical journals for clinical trials of vaccinesData updated by the World Health Organization on a monthly basis show that at least one new coronavirus vaccine is currently in clinical research and another candidate vaccine is in preclinical researchThere's a lot of good news coming out in just one dayOn the same day, the British medical journal The Lancet published the results of two new coronavirus vaccines from the Chinese and British teamsResearchers such as Chen Wei, member of the Institute of Bioengineering of the Institute of Military Medicine of the Chinese Academy of Military Sciences, Professor Zhu Fengcai of the Center for Disease Control and Prevention of Jiangsu Province, published a paper on the same day that they conducted a phase clinical trial of a adenovirus vector recombinant new coronavirus vaccine and showed that the vaccine was safe and could induce an immune responseIn a press release from The Lancet, Zhu said phase clinical trials provide further evidence of the safety and immunogenicity of vaccines in a wider population compared to phase clinical trials, which is an "important step" in evaluating candidate vaccinesOn the same day the Team at Oxford University published a report in The Lancet reporting that a clinical trial of a new coronavirus vaccine involving healthy adults had yielded preliminary resultsThe chimp adenovirus vector vaccine evaluated in the trial induces a strong immune response from the body's immune system without serious side effectsThe team is currently conducting larger vaccine clinical trials in the UK, Brazil and South AfricaAlso in Japan, Russia, Germany and other countries scientists also announced the progress of research and development of vaccine projectsThe new Crown Virus Vaccine Project of the Russian Ministry of Defense and the National Research Centre for Epidemiology and Microbiology of "Gamalea" completed clinical trials of some volunteersThe Russian Defense Ministry said the results showed that all vaccinated volunteers had an immune response and no side effectsThe vaccine was developed by the National Research Centre for Epidemiology and Microbiology in The "Gamalea" in two batchesOn the same day, German bio-technology company and Pfizer also announced the joint development of a messenger RNA () vaccine clinical trial preliminary data vaccine induced the human body to produce a robust specific antibody and cell responseIn total, the volunteers received two different doses of vaccination sat out the day and one of the volunteersEarlier this month, scientific institutions in other countries also reported progress on the new coronavirus vaccineA study published in the New England Journal of Medicine on JanThe vaccine was developed by the U.SNational Institute of Allergy and Infectious Diseases in collaboration with U.Sbiotech company ModenaModena will launch a randomized double-blind control clinical trial on The Month to further assess the efficacy, safety and immunogenicity of the vaccineThe clinical trial will be conducted in the United States to recruit 10,000 volunteersThe U.Sgovernment launched Operation Querfu this month to accelerate the development of a new coronavirus vaccine by the Department of Health and Human Services, the Department of Defense and other departments with the goal of producing hundreds of millions of doses of the vaccine by the yearFda Director Stephen Hahn said this month that the agency has approved a vaccine to be put into clinical trials and other vaccines are being preparedIn addition, the new Crown Virus Vaccine Research and Development team at the University of Queensland in Australia, Chulalongkorn University in Thailand and other institutions also reported positive results this monthAlthough research on the new coronavirus vaccine has been reported, experts have also pointed out that there are many risks and challenges such as virus mutations, as there are uncertainties in vaccine development and clinical trialsExperts call for an objective and rational scientific attitude towards vaccine researchMichael Ryan, executive director of the WHO Emergency Project, said on Monday that there was no firm timetable for the delivery of the new coronavirus vaccineWhile preliminary trial data on some candidate vaccines are promising, it is still not possible to predict which vaccine will be fully clinically effectiveThe possibility of a candidate vaccine by the end of this year shows that the new coronavirus is effective but the key question is whether vaccine capacity can keep up with demandSaudi Arabia's Middle East newspaper recently reported that while some pharmaceutical companies have announced significant progress in clinical trials of their new coronavirus vaccine, researchers caution against being too optimistic to wait for further test results Kenneth Fraser, chief executive of Merck Pharmaceuticals, said there was no guarantee that the vaccine being developed would work Other studies have shown that antibody levels in the body drop after a period of recovery from a person with a new coronavirus How the new coronavirus vaccine provides long-term immunization and how to deal with possible virus mutations will require the joint efforts of national scientific teams WHO calls on all countries to consistently adopt "government-wide, whole society-wide" prevention and control measures before the new coronavirus vaccine is officially available
