Whether a tumor patient can get the new crown vaccine or not needs to be judged based on several factors such as whether the tumor patient’s condition is stable, whether the patient is undergoing treatment, whether the patient is allergic to the vaccine, etc. 1. Tumor patients who have undergone radical surgery and are currently undergoing chemotherapy, radiotherapy, immunotherapy, or targeted therapy should withhold vaccination; 3. Not recommended: If a tumor patient has been cured but also has a combination of serious acute or chronic diseases, such as severe pneumonia, acute heart attack, etc., it is not recommended to get the new crown vaccine. It is also not recommended for patients with uncontrolled malignant tumors to receive the New Crown vaccine, because malignant tumors are wasting diseases, which usually lead to poor health and reduced resistance, and patients are more likely to have adverse reactions such as fever after receiving the New Crown vaccine. Usually, one should avoid going to public places with high traffic flow and crowded people as much as possible, and avoid close contact with patients with neo-crown. In daily life, you should pay attention to eating more high-quality protein, such as milk, eggs, soy products, etc., and increase exercise appropriately to enhance physical fitness, which can play a role in the prevention of Newcastle pneumonia.
