Vaccine sequelae do not reappear after 10 years, and usually only some adverse reactions to vaccination occur for a short period of time. The vaccine itself is an antigen, that is, a protein with specificity that, after vaccination, causes the body to produce an immune response, which in turn causes antibodies to be produced within the body to kill the virus and prevent disease. If this protein causes damage to the body, it usually appears at an early stage. After vaccination, some people may experience some uncomfortable symptoms within 24 hours, such as redness, swelling and pain at the vaccination site, dizziness, weakness, vomiting, etc., but most of them will be relieved on their own within 72 hours. If the symptoms are not relieved after 72 hours or if the symptoms are heavier and keep getting worse, you should seek medical attention to relieve the uncomfortable symptoms. Pay more attention to rest, light diet, eat more fruits and vegetables, and drink more water after the situation improves. If the problem occurs 10 years after vaccination, it may be caused by other reasons, such as irregular habits, changes in personal constitution, adverse effects of other diseases, etc. It is not necessarily caused by vaccination, but should be judged in the context of your own specific situation and seek medical attention if necessary.
