You can usually drink almond milk after the third vaccination. The main effect of the vaccine occurs in the immune system and does not conflict or interact with the diet, so it is safe to drink almond milk. After vaccination, some people may experience adverse reactions to vaccination, such as malaise, fever, diarrhea and abdominal pain, nausea and vomiting. It is recommended to drink plenty of warm water after vaccination to promote the body’s metabolism. Adverse reactions will usually resolve on their own, so please do not be overly alarmed. After vaccination, you need to stay in the hospital for about half an hour for observation, and leave the hospital only when you are not feeling unwell and have been examined by a doctor. After vaccination, you should pay attention to rest in your daily life and try to avoid over-exertion. After an adverse reaction occurs, immediately go to the hospital for examination and diagnosis, and under the guidance of the doctor for appropriate treatment.
