Daily care: After receiving cervical cancer vaccine, it is necessary to do daily care, including not touching water or scratching the vaccination site for three days, paying attention to rest and avoiding strenuous exercise. 3. Avoid pregnancy for 3~6 months: Cervical cancer vaccine has a certain degree of toxicity, so after vaccination, pregnancy should be avoided for 3~6 months. 4.
