Oxford-AstraZeneca Vaccine Final Exam
Vaccine for COVID-19 Developed by the University of Oxford, 70% of people do not get COVID-19. In a grand experiment stage 3
The result was both a victory and a disappointment. After the vaccines Pfizer and Moderna provided 95% protection against COVID-19.
The Oxford vaccine, however, is much cheaper. It is also easier to store and ship around the world than the other two vaccines.
Therefore, the vaccine will play an important role in the fight against the COVID-19 outbreak. If you are certified by the regulatory authority
There is also some remarkable data on the results of another Oxford vaccine trial: Getting the vaccine in the correct dose can increase your protection by up to 90%.
The Oxford researchers developed the vaccine in about 10 months from a typical 10-year process.
Professor Sarah Gilbert, creator of the vaccine, said: “Today’s announcement brings us one step closer to a time when we can use the vaccine to end the harm. [จากไวรัสโคโรนา] One more step ”
UK Government 100 million doses of Oxford vaccines have been reserved, enough to vaccinate 50 million people.
How was the result of the experiment?
More than 20,000 volunteers participated in the experiment. Half of them are in the UK. And the rest in Brazil
Researchers say This vaccine is 70% effective against COVID-19 infection.
When a volunteer was vaccinated in two “high” doses, 62% of the infection was prevented, but this figure would reach 90% if they received a “low” dose of vaccine followed by one dose. “Stop” once, but the exact reason remains unknown. Because they are different?
Professor Andrew Pollard, lead investigator of the trial, told the BBC: “We are very pleased with these results.”
He said the 90% success rate was “staggering” and he meant it was “staggering.” Will have a greater number of export doses
When will the COVID-19 vaccine be available?
Additionally, lower levels of asymptomatic infection were also seen in the low-dose and high-back first-dose vaccine groups, which “means we can stop the virus,” said Professor Paul. Lard said.
When will I get the vaccine?
In the UK there are 4 million doses of the vaccine ready and 96 million doses await deliveries.
But now I still can’t do anything. Until the vaccine has been approved by a regulatory body that evaluates the safety and efficacy of the vaccine. So it has to be manufactured to a high standard. The process will take place in a few weeks.
Yet the UK is ready to start vaccinating as many people as never before. This is more than the annual flu vaccination schedule or pediatric vaccination.
Nursing home residents and staff will be the first to receive the vaccine. This was followed by healthcare workers and people over the age of 85, who were then gradually chasing down the descending age group.
Made in thailand too
On October 12, the Thai Astraseneca Ministry of Public Health, Siam BioScience Co., Ltd. and SCG jointly announced the production of this vaccine in Thailand in the first half of 2021.
A British government publication states that Mass production of vaccines at the Siam BioScience plant This will allow people from Southeast Asia to have access to this vaccine widely and equitably. By Astra Seneca Vaccines will be provided during the outbreak free of charge. Collaborated with Siam Bioscience to establish a production line. And transfer technology to
Dr. Nakorn Premsri, Director of the National Vaccine Institute, interviewed TNN about 3 AstraZeneca conditions. By establishing a vaccine production base in Thailand Posted on the website on November 11.
- The Thai government will also have to subscribe to the vaccine produced by Siam BioScience. Based on the principle that the products produced by the Thais, the Thais use by themselves under the AstraZeneca brand
- The Thai government must allow the export of the covid vaccine produced. If it is not rated, it means that after the vaccine is produced, Thailand can order 25 million doses of the vaccine per year and the remainder of AstraZeneca’s vaccines will be exported to other countries. Because they don’t want to be hoarded. This is for the benefit of public health.
- The Thai government must reserve the vaccine in advance. There is an advance payment. What is in common risk Why AstraZeneca Money should be used to buy raw materials used in the production of vaccines. To be able to process production in a timely manner in case the experimental vaccine was effective. But there will be a risk that If the vaccine does not work, it is a common risk. If you don’t book in advance, you must wait in line. Thailand will become a vaccine production area But I have not used the vaccine yet because other countries have already booked in advance Which is certainly not good for the people of the country.
How does this vaccine work?
The Oxford vaccine is a common genetically modified influenza virus that used to infect chimpanzees.
Genetic modifications have been made to prevent infections in humans. The virus carries a model of a part of the corona virus known as the button protein in human cells.

When these planes enter a person’s body then they begin to produce the corona virus protein button. That the immune system remembers that it is harmful to the body AND trying to get rid of it
When the immune system actually encounters the coronavirus, it knows how to deal with it.
Are the results disappointing?
After Pfizer and Moderna have produced a vaccine that is 95% effective against COVID-19 infection The efficacy of the Oxford vaccine at 70% is disappointing.
However, a month ago Figures above 50% would have been seen as a victory.
The vaccine is also stored at normal refrigerator temperature. That means it can be shipped to all over the world. Unlike the Pfizer-Biotech and Moderna vaccine that had to be kept at much cooler temperatures.
AstraZeneca, Oxford partner in vaccine production Preparing to produce 3 billion doses of the vaccine for people around the world.
How will this vaccine change people’s lives?
It took years to develop a vaccine. However, vaccinating tens of millions of people in the UK and billions around the world is a huge task.
People will not be able to return to their normal lives tomorrow. But the situation will improve very quickly.
