I cannot deny that The question
สมัครสมาชิก SLOTXO that people around the world are waiting to answer right now is the COVID-19 vaccine. When will it be available for real use? After having an expert and concerned came out, I hope that The earliest is at the end of this year. While many parties believe that The first quarter of 2021 is likely to be a definite time to see a safe and effective vaccine for use.
CNN reports that pharmaceutical companies and governments around the world are accelerating the development of the COVID-19 vaccine. Each other urgently But still not a clear signal from either side that When will the vaccine be available?
Anthony Fauchie, MD, director of the US National Institute of Allergy and Infectious Diseases. Expressed hope that At least one of the drug companies' vaccine development programs At the US government The funding will be successful this year and 200-300 million doses of the vaccine will be ready for use by early next year.
But many doctors commented that Seeing the development of a vaccine against COVID-19 Successfully ready for use in January next year. It is setting a goal that is considered very high.
The reason some people have voiced their doubts about this is because, as a rule, any vaccine is developed. However, it has to go through a number of steps to be sure that The drug works well and is safe for recipients too, said female physician Emily Erbelding, an infectious disease specialist at the National Institute of Allergy and Infectious Diseases, who can take up to 8-10 years.
In developing a vaccine To start with animal testing Before entering the three phase human trials, phase 1 will be a small group of volunteers to assess their safety. Which if there is no problem It will move to Phase 2, where there will be hundreds more volunteers participating. The experiment will be random. And people who are at risk, such as old age or have health problems, are also joined, and when everything is done well. It will go into Phase 3, a phase that focuses on the efficacy and safety of the drug. By experimenting with thousands or tens of thousands of volunteers So that researchers can evaluate the side effects of drug use
In the past, there have been some reports of the negative effects of accelerating vaccine development and use, for example, in 2017 the Philippine government accelerated a plan to vaccinate 1 million children with dengue fever, but this had to be halted. Success due to safety issues After 10 vaccinated children were reported dead or in 1976 in the United States, there was a swine flu pandemic. And the government of President Gerald Ford ignored the World Health Organization warnings. And continue to vaccinate everyone in the country to deal with the new virus. But after 45 million people were vaccinated, researchers found About 450 people have symptoms of nerve inflammation. Which is a worrying proportion And finally, at least 30 people died.
To the question that if vaccine production is accelerated Is it safe? Dr Francis Collins, director of the US National Institutes of Health, said that if a new vaccine is developed but without a thorough investigation, it should not be released at all. Because there is nothing to confirm that The vaccine is safe And can actually help protect drug recipients
However, pressures on vaccines have led scientists to try to accelerate the whole process, such as in Seattle. And the city of Atlanta That researchers plan to test the vaccine on both animals and humans simultaneously, while Dr. Anthony Fauchy, director of the National Institute of Allergy and Infectious Diseases of the US, said that the production of the vaccine will be started. In some cases, such as a joint program between the US government and pharmaceutical company Moderna Inc, in the hope that If the results of the experiment were successful Millions of people will have the opportunity to use the vaccine right away.
CNN news reports that there are currently over 120 vaccine development programs around the world. Some projects are significantly more advanced than others, including four in the US and five in China, and one in the UK that has already started human trials. According to the World Health Organization
In regards to the vaccine price that some parties are concerned about Medical Organization Without Borders They called on world leaders to negotiate with drug companies to sell the COVID-19 vaccine at a cost, because the current situation is not the time for anyone to stick to the profitability principle. Meanwhile, governments have already contributed more than $ 4.4 billion to vaccine development.
Another question that is skeptical is Even after the vaccine has been released Will the person who has been injected will have to come back to receive the drug? Or just one needle is enough Which the researchers themselves are still unable to answer But many people believe Should have injected more than 1 needle for real results.
In the end, is the accelerated vaccine really effective against COVID-19? David Navarro, professor of global health at Imperial College London, said the reality is. No one has yet been able to fully say that This effort will actually be successful. And more than that If humans are unable to immunize the new coronavirus after vaccination This drug will not have any benefit.
