The vaccinees can exercise moderately after the new crown vaccine, such as walking and yoga, but they should not exercise strenuously, and generally avoid high-intensity exercise for 3 days to avoid dizziness, muscle aches and other uncomfortable reactions. In addition, the following points should be noted: 1. After the vaccination, the vaccinees need to stay at the vaccination site for 30 minutes for observation, and if discomfort occurs during the observation period, medical staff should be informed promptly for treatment; 2. Keep the vaccination site clean and dry, avoid scratching with hands, and pay attention not to take a bath for 24 hours to avoid infection of the wound after encountering water; 3. Avoid eating spicy and stimulating food, smoking and drinking; 4. The protection rate of the new crown vaccine is not 100%, so you should wear a good mask after vaccination, keep a safe distance and pay attention to protection; 5. 6. For the vaccinees who have just finished vaccination, they should place the pressed swabs in the designated recycling containers and not take them away from the site, not to mention discarding them anywhere.
