How many shots does cervical vaccine have to take?

HPV vaccine is divided into three doses, which need to be injected within six months. The first dose can be chosen by yourself, the second dose is two months after the first dose, and the third dose is injected six months after the first dose. The vaccine should be injected on time. Too long a delay may affect the actual effect of the vaccine. The three doses of HPV vaccine are all the same, and there is no big difference, but the efficacy of each dose is different. The first injection will make the body produce a certain antigen, the second injection produces antibodies dozens of times the first time, the antibody action time is also greatly increased, the third injection is called to strengthen immunity, so the three injections are indispensable.
