The time of each injection of the nine-valent vaccine for cervical cancer is 0, 2 and 6 months respectively, that is, when the injection time of the first injection is set, the second injection will be given 2 months after the first injection, and the third injection will be given 6 months after the first injection, i.e. the total interval between the 3 injections is 6 months. At present, China requires 16-26 years old to receive the nine-valent vaccine, while abroad, the vaccine can be given until the age of 45. For women who are ready to receive the cervical vaccine, it is important to use birth control during the 6 months of the vaccination. If you become pregnant during this period, you need to inform your doctor immediately and have a proper maternity check-up, and then discuss with your doctor the time to continue with the rest of the vaccination after the breastfeeding period is over. Avoid touching water at the injection site for 3 days, take care to prevent infection, get plenty of rest, and avoid overly stimulating foods in your diet.
