At present, the vaccination work in Covid-19, Inner Mongolia has been carried out among the target population over 18 years old. On March 29th, the reporter interviewed Yan Shaohong, deputy director of the Second Institute of Tuberculosis and Prevention of the Center for Comprehensive Disease Control and Prevention of Inner Mongolia Autonomous Region, about the effective protection and adverse reactions of Covid-19 vaccine.
"Covid-19 vaccination is the most effective way to prevent and control the spread of COVID-19, which is the most economical and convenient." Yan Shaohong said that it is the duty and obligation of every citizen to vaccinate Covid-19 vaccine, and the masses should correctly understand the safety of COVID-19 vaccine and take the initiative to vaccinate.
Yan Shaohong said that almost all people have no immunity against Covid-19, and are generally susceptible to Covid-19. After the infection, some people will develop into severe illness, critical illness and even death. After vaccination, on the one hand, most people can gain immunity; On the other hand, through the orderly inoculation of COVID-19 vaccine, an immune barrier can be gradually established in the population, and the large-scale spread and epidemic of COVID-19 can be blocked.
At present, the vaccination work in Covid-19, the key population in the whole region, has come to an end, and the vaccination work for the target population over 18 years old has also started, with two doses of vaccination, with an interval of 2-4 weeks. The principle of vaccination work is still to adhere to informed, consent, voluntary and free vaccination, to coordinate the prevention and control of normalization with vaccination work, to prudently, steadily and orderly implement local territorial responsibility and industry supervision responsibility according to law, to promote vaccination work more safely, orderly and forcefully, to gradually expand the coverage of people, and to vaccinate as many people as possible to protect the health of the broad masses of the people.
"The protective efficacy of vaccines used in China has reached the relevant standards of National Medical Products Administration’s Guiding Principles for Clinical Evaluation of Preventive Vaccines in novel coronavirus (Trial), and it also meets the index requirements recommended by the World Health Organization’s Covid-19 Vaccine Target Product Characteristics. The immune persistence of inactivated vaccine in Covid-19 is still under continuous observation. The evidence suggests that the vaccine protection period can reach at least half a year. " Yan Shaohong admits that no vaccine can guarantee that the vaccinated population will have 100% protection effect. Therefore, after vaccination with Covid-19 vaccine, the protection standard cannot be lowered in daily work and life. The general public should still keep the awareness of preventing Covid-19 infection and spread, and do personal protection. Whether vaccinated or not, they should continue to wear masks indoors or in closed places where people gather, and follow the specific prevention and control measures in various places.
Regarding the adverse reactions of COVID-19 vaccine, Yan Shaohong said that the vaccine is an exotic antigen to human body. Due to the characteristics of the vaccine and individual differences, there will be some adverse reactions after vaccination, but the incidence rate is still relatively low. At present, the adverse reactions monitored mainly include local reactions and systemic reactions. After inoculation, local reactions will cause pain, some will appear redness and some will appear induration, but these local reactions do not need to be treated and will heal on their own. The general reactions are mainly headache and fatigue, and some may have low fever. (Reporter Zhang Wenqiang)
