According to the basic investigation, two medical staff, one is an emergency doctor and the other is a high-tech pathologist, which may be caused by accidental exposure. At this stage, the actual reason has been further investigated. Medical staff are the first group to be vaccinated, so some people obviously wonder why they still feel sick after being vaccinated.
Why does the flu still appear after vaccination?
1) The vaccine cannot be 100% safe. In the past, because the domestic epidemic situation was well controlled, everyone thought that it was not easy to get infected after vaccination in COVID-19, but in fact, it is not uncommon to get vaccinated in COVID-19. However, in Britain, there are still 1 10,000 people infected with COVID-19 among the 6,543.8+3 billion people who have been completely vaccinated.
Therefore, at the beginning of marketing and promotion, authoritative experts said that although the pre-vaccine in COVID-19 could not completely block the spread of the virus, it had a certain probability of maintenance, and it was crucial that it could not be maintained. This medical staff and the medical records after the previous four vaccinations are not very critical, which also illustrates this point.
2) COVID-19's gene mutation led to "breakthrough infection". According to the doctor of Guangzhou CDC, the virus infected in this medical record infected high-throughput sequencing with the same aspect ratio, all of which are Indonesian mutant viruses! Professor Liang Zong 'an, director of the Department of Inhalation and Critical Rehabilitation Medicine of West China Hospital, mentioned in an interview with The Paper that compared with the initial virus infection in the United States, Brazil, Mexico and other places, Indonesian virus infection has one more gene mutation domain and three gene mutations (L452R, E484Q, P68 1R)! It is the gene mutation at these three points that makes the mutant virus in Indonesia more contagious and spread faster. According to biologists' research results, a gene mutation E484Q of the mutant virus is beneficial to improve the immune escape of virus infection, but it can partially bypass some neutralizing antibodies in the body, which may reduce the ability of people to maintain COVID-19 vaccine.
According to the warning of outpatient doctors in a hospital in Maharashtra, it is found that viral infection with new gene mutation can cause false negative of nasal swab. This is because COVID-19, a gene mutation, is more suitable for breeding in the lower respiratory tract, and the low viral load in the respiratory tract is likely to lead to false negative detection, which does not mean that today's detection reagents are ineffective.
3) Medical staff themselves are also key targets. In the whole process of pneumonia epidemic, medical staff, as frontline soldiers, are also high-risk groups. And one of them is an emergency doctor, so as a medical staff, we should also protect ourselves and do a good job of safety protection.
result
Although vaccination can not guarantee the maintenance of 100%, it can prevent a large-scale outbreak in COVID-19 and avoid serious infection. In addition to vaccination, everyone needs to protect themselves and reduce the risk of infection as much as possible. We look forward to the early end of the global COVID-19 epidemic and the revival of everything.
