New Crown vaccination is not recommended for the time being three months after surgery for lung adenocarcinoma. Lung adenocarcinoma belongs to non-small cell carcinoma of lung cancer. Aggressive surgery is the main means for early-stage patients, while late-stage surgery is mainly to prolong the patient’s life. After surgery, radiotherapy is usually needed. Three months after surgery, patients are still in the treatment period, and their condition is not stable yet. At this time, patients are using radiotherapy or chemotherapy, or even immunosuppressive treatment, and their immune resistance is poor, so they are not eligible for the New Crown vaccine. The new crown vaccine is contraindicated for people who are suffering from fever, acute exacerbation of acute or chronic diseases, or uncontrolled severe chronic diseases. Therefore, it is not recommended to receive the New Crown vaccine at this time. At the same time, long-term use of immunosuppressive drugs will affect the protective effect of the vaccine, so it is recommended that patients who have stopped chemotherapy for at least 3 months and are in stable condition before considering vaccination with the New Crown vaccine. It is recommended that patients go to a regular hospital department for consultation and consultation, and be determined by a professional physician after a comprehensive assessment, do not blindly vaccinate.
