The adverse reactions after HPV vaccination are similar to those after conventional vaccination, including allergy and even anaphylaxis, so you need to observe for a period of time at the health center where the injection was given, and if you have any uncomfortable reactions, you need to communicate with the medical staff. In addition, after returning, pay attention to whether there are any uncomfortable reactions such as redness, swelling and hard nodules in the area where the injection was given, and whether there are symptoms of fever, especially uncomfortable reactions such as chest tightness and shortness of breath, which still require prompt medical consultation. Most of the side effects after HPV vaccination are very mild, and very serious side effects are very rare, so don’t be nervous. It is also important to eat before the vaccination to prevent hypoglycemic shock. If you have a previous acute infection, such as a cold or fever, try to avoid getting the vaccine at this time to avoid discomfort and aggravation. In conclusion, the HPV vaccine is basically very safe and can be used with confidence. If you have any uncomfortable reactions, go to the clinic and communicate with your doctor in a timely manner, especially if you have serious uncomfortable reactions, you must go to the hospital and communicate with your doctor in a timely manner.
