How often should the cervical cancer vaccine be given?

The effectiveness of injected vaccines is limited, so many vaccines need to be injected multiple times. Similarly, the vaccine to prevent cervical cancer is also timely, but many people don't know it. So, how long does the vaccine against cervical cancer last? How often should the cervical cancer vaccine be given?

How often should the HPV vaccine be given?

The HPV vaccine is given in three injections, which take a total of 6 months to administer. The bivalent HPV vaccine is administered at months 0, 1, and 6. The quadrivalent and nine-valent HPV vaccines are administered at months 0, 2, and 6. Vaccine recipients should receive the injection and dose on time. Delaying the vaccination for too long may affect the actual preventive effect.

Is it reasonable to only give one shot of the HPV vaccine?

The normal injection procedure for HPV is three injections, which are usually completed within half a year. Only after the injection is completed can it effectively prevent the occurrence of cervical cancer in women. If you only get one shot, it will affect the actual prevention effect.

HPV vaccine three injections

The ingredients of the three injections of HPV vaccine are all the same and there is no difference, but the effects of each injection are different. The first injection will cause the body to produce a certain amount of antigens, and the antibodies produced by the second injection are dozens of times that of the first reaction, and the duration of the antibody effect is also greatly increased. The third shot is called booster immunization, which can increase the antibody titer and make the prevention effect last longer. So the three needles are indispensable.

The vaccine to prevent cervical cancer is injected intramuscularly. According to relevant data survey reports, the current effective period of cervical cancer vaccine is at least 4 years. However, since the vaccine to prevent cervical cancer has only been on the market for more than ten years, its effective time still needs to be upgraded. With the improvement of the vaccine, its effective time will also increase to a certain extent.

The vaccine against cervical cancer is not like other common vaccines, which can be injected once. The vaccine against cervical cancer is divided into three doses, so three injections are required separately. And it should be noted that the three injections need to be carried out within 6 months. To put it simply, after the first shot, the second shot is given in the second month, and the third shot is given in the sixth month. Only if the injection is carried out on time and all three injections are completed can the effect of preventing cervical cancer be achieved. Female friends should keep this in mind.
