How effective will the vaccine be on the Omicron variant? How will this virus be identified, know - the opinion of experts
Omicron, a dangerous variant of the corona virus, has raised the concern of the whole world. This is being said to be the most dangerous variant of Corona. Omicron was first identified in South Africa, but now this dangerous variant of the corona virus has spread its feet in Europe and Asia including India. After this, this variant has created panic in the whole world. It is also being said that preparations for a new vaccine are underway for the new variant. In such a situation, the question arises whether the old vaccine is less effective on this variant? What is the opinion of scientists and doctors in all these matters? How is it tested and what are its symptoms?
how effective is the vaccine
1- Dame Sarah Gilbert, Professor of Vacology at Oxford University, says that this variant of Corona is slightly different. This may make the antibody from the vaccine or the antibody from infection with another variant less effective in preventing infection with Omicron, but this does not mean that the vaccine is not effective. Gilbert says that the future epidemic after Corona may be more dangerous. He said that by taking lessons from the mistakes we have committed during Corona, we have to be prepared to fight such epidemics with better preparedness in future. He said that the world should ensure that time is not wasted during Corona and be better prepared for the next virus.
2-AIIMS chief Dr Guleria told news agency PTI on Sunday that Omicron has had more than 30 mutations. These mutations or changes have occurred in the spike protein region of the virus. He said that due to the mutation in the region of the virus's spike protein, the Omicron variant can develop such ability in which it can evade immunity. This means that the body's immunity caused by vaccines or other factors does not affect it. Guleria said that in such a situation all the corona vaccine manufacturing companies of the world will have to review it. He said that this is necessary because most vaccines develop antibodies that fight this protein. Guleria further said that the vaccine works on this basis. The AIIMS chief said that Omicron is doing mutation, that is, changing its form rapidly, so it is possible that many vaccines may not be effective.
Is it possible to test Omicron variant with RTPCR?
1- Can Omicron be detected by RTPCR test? In this case, Yashoda Hospital doctor PN Arora says that RTPCR test can only detect whether a person is corona infected or not. RTPCR test detects the presence of virus in the body. He said that the variant could not be detected by this test. Genome sequencing becomes necessary to detect the variant. He said that not all samples can be sent for genome sequencing. He said that the whole process is very complicated, slow and costly.
In the context of 2- omicron, this difference is related to the mutation of the spike protein. This is that part of the virus, which changes itself repeatedly. It protects itself from drugs and disease resistance cells. For this reason it is difficult to test it. In such a situation, most of the investigations will be able to tell whether a person has got corona infection or not. If a person is infected with the Omicron variant, then for this the help of genetic sequencing will have to be taken.
What are the symptoms of Omicron infected person?
The World Health Organization confirmed the corona variant in South Africa on 24 November. The organization said that this new variant has been found in South Africa. The World Health Organization had expressed concern over this variant of the corona virus and named it Omicron. The organization said that there are many mutations taking place in this variant. This puts the person at risk of getting infected again. Very mild symptoms have been found in infected persons. Body pain and extreme tiredness have been reported in most of the patients. However, the impact and severity of this variant have not been estimated yet.
