Vaccine testing against the coronavirus, which is being developed by Oxford University in the UK and the pharmaceutical company AstraZeneca, has resumed. Oxford said the trial was resumed in the UK on the recommendation of an independent committee reviewing vaccine safety and the UK Medicine and Healthcare Products Regulatory Agency (MHRA).
The final clinical trial of the vaccine was postponed last Tuesday after a female volunteer who participated in the vaccination test showed suspicious adverse reactions. The suspension was resumed amid concerns.
The vaccine has been tested on about 18,000 people worldwide. Although it is common for thousands of patients to be vaccinated, the safety of each participant will be carefully assessed, according to an Oxford statement. Last year, AstraZeneca reported a “regular” break in a final clinical trial due to “an unexplained illness.”
Oxford has not officially made public what problems were seen in those volunteers. But the New York Times reported that the volunteers had ‘transverse militia’, a spinal cord injury. It is believed that the disease caused by a viral infection can affect the human spinal cord.
British Health Secretary Matt Hancock tweeted that the resumption of testing was welcome and a good thing for everyone. Mr. Hancock said the postponement of the vaccine test showed that the UK’s safety was always a top priority and would help its scientists find effective and safe research as soon as possible.
The results of the final, third test of the vaccine are being watched with great interest around the world. About 30,000 people in the United States, the United Kingdom, Brazil, and South Africa are taking part in the third trial.
Oxford and AstraZeneca expect up to 50,000 participants worldwide in the third phase. In addition, the company says the test will be extended to Japan and Russia. In the third stage, thousands of people are vaccinated to test its effectiveness, side effects, and whether it is safe in humans, and this process can take many years.
Of the nearly a dozen vaccines being developed around the world, everyone has confidence in the vaccines being developed by AstraZeneca and Oxford University. The United Kingdom, Australia, the United States, the European Union, and others have agreed to buy tens of millions of doses. The UK has agreed to buy 340 million doses from various companies, but will only take 100 million from AstraZeneca.
According to the World Health Organization (WHO), about 180 vaccines are currently being tested worldwide. But so far no one was able to send in the perfect solution, which is not strange. A senior British scientist has expressed hope that the covid vaccine will be available in the UK within nine months. Professor Peter Opensa, an adviser to the government’s scientific group SEZ, said there was a lot of hope after the news of the resumption of vaccination in Oxford. However, other scientists, including Peter, have said that vaccines will not be available for the second wave of corona infections, which are likely to occur this winter. He is of the opinion that this vaccine is not possible if it is easily available in all the countries of the world.

Astrakhan chief executive Pascal Strait said last Thursday that the vaccine could be available by the end of this year or early next year if trials begin early. He was of the opinion that it would also depend on how soon the regulatory body approves the vaccine.
Efforts are now being made worldwide to develop a vaccine against covid. The United States has so far invested 10 billion in efforts to bring the vaccine to market. The United States announced on May 21 that it would pay 1.2 billion to AstraZeneca. If the vaccine is safe and effective, the United States will receive at least 300 million vaccines. Although vaccine research usually takes 5 to 10 years to become available on the market, scientists are trying to bring the covid vaccine within a few months.
Pharmaceutical companies and governments are now risking billions of dollars. The World Health Organization believes that the vaccine will be recognized by the end of this year and will be available everywhere by at least the middle of 2021. Russia says it has developed a covid vaccine called “Sputnik-5” which has developed immunity in patients and will be available to the public in October. China says the vaccine has been successfully developed and is now available in the military. However, questions have been raised about the effectiveness of the vaccine, in which both countries have developed so quickly.
Meanwhile, US company Pfizer and German biotech, which are at the forefront of vaccine development, announced on Saturday that 44,000 people would take part in an international test, according to the Financial Times. The company has said that the initial test target of 30,000 people will be reached next week. At present, companies like Medorna, Valneva, Nova Vax, Sanofi Pasteur, and GSK are also at the forefront of covid vaccine development.
