Booster shots generally refer to the new coronavirus vaccine booster. It is wrong to say that booster shots are not recommended for young people. In the epidemic stage, vaccination is the most direct and effective means of preventing new coronavirus infection, and the current preventive measures taken by our country are that those who can be vaccinated need to be vaccinated as early as possible throughout the entire process, so as to establish an immune barrier in the shortest possible time and protect the health of the people. After vaccination, even if infected with the new coronavirus variant, can effectively reduce the morbidity and mortality rate. Young people can receive booster shots of the new coronavirus vaccine, but it is necessary to pay attention to the contraindications of the vaccine. However, it is necessary to pay attention to the contraindications of the vaccine, i.e. it is not suitable for people who are allergic to the components of the vaccine, and it should be postponed during the onset of an acute disease. Therefore, in order to better cope with the epidemic prevention and control trend at this stage, it is recommended that young people should get vaccinated in a timely manner after consulting with community hospitals to strengthen their resistance to the virus and reduce the risk of contracting the virus in the future in the course of study, life and recreation.
