Whether a person with a chronic disease can receive the New Crown vaccine depends on the patient’s own condition. If the chronic disease can be better controlled by medication and the body is in a more stable state for a long period of time, the New Crown vaccine can be administered after evaluation by a professional doctor. On the contrary, patients with more serious chronic diseases or chronic diseases in acute attack and poorly controlled by medication are advised to withhold the New Crown vaccine. People with chronic diseases are in a state of long-term physical exertion and may be prone to adverse reactions after getting the New Crown vaccine due to lower resistance, which may aggravate disease progression. In addition, people with chronic diseases may not be able to produce sufficient antibodies due to their own conditions, which may reduce the effectiveness of the New Crown vaccine. Therefore, it is not recommended for people with chronic diseases to receive the New Crown vaccine, but if they have special vaccination needs, they can be evaluated by a professional doctor according to their conditions at the time to decide whether they can receive the New Crown vaccine. After getting the New Crown vaccine, you should observe the vaccination site for at least 30 minutes and need to react to the doctor or vaccination personnel if you have any uncomfortable symptoms to avoid adverse consequences. 24 hours after vaccination, the vaccination site may show signs of soreness, pain, redness and swelling, and a few people may have symptoms such as fever, malaise, nausea and dizziness, which can usually be relieved on their own with proper rest. Keep the vaccination site clean and dry, and avoid scratching with your hands to avoid infection. Keep your diet light, get enough sleep and avoid strenuous exercise.
