According to the Daily Mail on January 3, a scientist who helped develop the Oxford vaccine warned that the Oxford vaccine currently on the market may not be effective for highly infectious mutant viruses found in South Africa.
Bell, a professor of medicine at Oxford University, said that the Oxford vaccine can effectively deal with the variant virus found in the UK, but not the 501 virus found in South Africa.
V2 variant virus, because 501. The V2 virus has undergone a dramatic change in protein structure.
Bell told The Times Radio, “My intuition is that the existing vaccine is effective for mutant strains found in the UK, but we need to know more about the mutant strains found in South Africa.”
In December, the UK’s coronavirus cases broke out on a large scale, and the UK’s first “warning bell” on the harm of VUI-202012/01 variant virus.
The variant has been found in countries such as Australia, Italy, Iceland, Spain and the Netherlands. At the same time, 501. V2 variant strain, P681H variant strain appears in Nigeria.
Among them, 501. V2 strains are more harmful than VUI-202012/01 strains found in the UK.
At present, several countries, including the United Kingdom, Germany, Saudi Arabia and Turkey, have banned tourists from South Africa, but 501. V2 strain.
Typically, a coronavirus vaccine is prevented by “teaching” the human immune system how to fight against pathogens.
Vaccines create antibodies that create and store anti-disease proteins by “grabbing” the spine proteins of the pathogen, so that they can resist “invasives” in the future.
But if the spiny protein changes structurally and the protein cannot be recognized, it means that the human body may have difficulty in dealing with the virus that comes to attack the second time, resulting in a second infection.
According to The Sun, 540 GP vaccination sites and 101 hospitals in the United Kingdom will launch the first batch of 530,000 doses of COVID-19 vaccine developed by Oxford University and AstraZeneca on January 4, and will take the lead in providing 500,000 doses of vaccines to vulnerable people this week.
It is reported that the British National Health Service (NHS) has ordered 100 million doses of vaccine for 50 million people, and Prime Minister Johnson has promised to vaccinate tens of millions of British people within three months.Click to enter the topic:
