Booster shots can be given after removal of intestinal polyps, and it is recommended that the New Crown vaccine can usually be used after 1 week when contraindications to the New Crown vaccine have been ruled out. Currently, clinical gastrointestinal polypectomy is performed under minimally invasive gastroscopy or colonoscopy, which generally does not cause significant harm. Most patients do not experience any significant discomfort after gastrointestinal polypectomy, but they need to be careful not to eat spicy and stimulating foods, and avoid smoking and drinking alcohol for 1 week after the operation. As gastrointestinal polypectomy causes less trauma to the human body and the physical state recovers faster, one week after the completion of gastrointestinal polypectomy, excluding acute infections, allergies, the presence of neurological disorders and other contraindications to the new crown vaccine, you can be vaccinated with coronavirus vaccine. After the new crown vaccination, it is necessary to eat a light diet, do not stay up late, and exercise reasonably.
