Try to leave more than two weeks between the nine-valent vaccine and the new coronavirus vaccine, and observe whether the patient has any adverse reactions after receiving either vaccine. The nine-valent vaccine can prevent HPV infection, and the new coronavirus vaccine can prevent and reduce the chances of the body contracting the new coronavirus pneumonia. If these two vaccines are given at the same time, there is a possibility of adverse reactions and such adverse reactions shown by the body afterward may also lead to misdiagnosis by the doctor. In order to avoid any conflict between the nine-valent vaccine and the new coronavirus vaccine, the two vaccines should be given more than two weeks apart. If the adverse reactions to one of the vaccines are more serious, you can extend the duration of the other vaccination. Try to choose a local regular hospital or epidemic prevention center for vaccination, and observe for 30 minutes after the injection. If the body has serious adverse reactions, you need to communicate with your doctor.
