Nine-valent refers to the nine-valent HPV vaccine, and the 3rd dose of the nine-valent HPV vaccine can be delayed for 6 months. The normal vaccination schedule for the Septavalent HPV vaccine is 0, 2, and 6 months, which is a total of 3 vaccinations. This usually refers to a time when the 2nd shot is 2 months apart from the 1st vaccination and the 3rd shot is 6 months apart from the 1st. Vaccination is usually done strictly on time. However, if you are not able to receive the vaccination on time due to personal reasons, you can delay the 3rd injection for up to 6 months, and the whole vaccination can be completed within one year, as too long an interval will affect the effect of the vaccine. You should not touch water or take a bath on the day after the injection. Some people have fever and other reactions after the injection, then they need to go to the hospital in time.
