Cervical cancer annually diagnosed in 490,000 women and, in some cases, to defeat this terrible disease, modern medicine can not.In recent years, actively promoted the need for vaccination against human papillomavirus (HPV) infection that in 99.7% of cases it causes cancer.After administration of the vaccine in humans produces a strong immunity to oncogenic types of the virus, and the risk of cervical cancer significantly reduced.

In this article we will tell you about HPV, its transmission, types of vaccines, the rules of administration and the effectiveness of such measures to prevent cervical cancer.

Human Papilloma Virus (HPV) is one of the most common, and modern science knows about

100 of its species (strains).Each of them can cause changes in various human organs, and 15 of them recognized carcinogenic and can cause cancer of the penis or cervix.The most dangerous among them HPV types 16 and 18.

Vaccine against cervical cancer Infection with this virus may at oral, genital and anal sexual contact, during birth from mother to fetus and even simple physical contact with the skin of an infected person.It polygamous sex in most cases lead to HPV infection, and the peak of the probability of infection between the ages of 15-19 years.

After penetration of oncogenic types of the virus in the infected organism is not observed any specific symptoms for a long time.After many years of infection, "breaks" the DNA of cervical epithelial cells and causes them to rebirth in precancerous or cancerous.

in the vaccine against cervical cancer does not include live virus human papillomavirus.They consist of organic substances, which are similar to HPV, but can not cause infection.As additional components in them are elements from yeast, aluminum hydroxide, antibiotics and preservatives.Vaccines produced in the form of suspensions which are packaged in disposable syringes or vials (one dose each).

After vaccination, these substances affect the immune system and the body begins to produce antibodies which then prevent the consolidation of the virus in tissues.According to statistics, the introduction of these drugs can prevent cervical cancer in 90-95% of cases.

for vaccination can be used two types of HPV vaccines:

Both these vaccines can protect against the most oncogenic HPV types (16 and 18), and Gardasil can prevent the development of warts on the cervix, vaginal walls, vulva and skin aroundanus.Both vaccines are used for vaccination of girls and women, Gardasil can be used to prevent cancer of the penis in boys.

On the recommendations of the manufacturer and the WHO vaccination against HPV can be shown to boys and girls up to 26 years.Provided two age categories, which can be carried out administering Gardasil and Cervarix - 9-14 and 18-26 years.In Russia, this type of vaccine is included in the immunization schedule for girls 12 years old.

administration of the vaccine is recommended before the start of sexual activity, when the body has not yet been infected with HPV.If the graft is already living a sexual life, it is recommended before vaccination perform tests to determine the HPV in the body, ie. A. In the presence of infection with vaccination becomes senseless.

effective administration of vaccines Gardasil and Cervarix to persons over 26 years is quite low.There is evidence that vaccination of them older than 35 years of self-healing can accelerate the process of HPV, but these observations are not yet sufficiently scientifically confirmed.

administration of the vaccine Gardasil and Cervarix can be carried out in the absence of an elevated body temperature and after exclusion of contraindications and pregnancy.Prior to the first dose of the drug the doctor should be informed about the increased bleeding gums or inclination to bruise, taking medications or vaccinations, which were obtained in recent times.

Vaccination against HPV is carried out three times, the course consists of three intramuscular injections, which are carried out for six months.Thrust is carried out only in the shoulder or hip, t. To. In these places well developed muscular layer, and it is located as close to the skin.The vaccine is only effective when administered intramuscularly, and therefore the injection in the buttocks is not carried out due to the high probability of getting the drug into the subcutaneous fat.

first date of the introduction of Gardasil or Cervarix can be determined independently, the second - a month later, and the third - 6 months after the first vaccination.In some cases, in the absence of being able to perform revaccination within the time allowed after administration of the second dose of 1-2.5 months, and the third - 5-12 months.This delay will not have a major impact on the effectiveness of vaccination and immunization against HPV fully formed.

Vaccination can be conducted in the offices of vaccination clinics, gynecological hospitals, private clinics, district hospitals or specialized centers for vaccination.Some private hospitals offer services to the HPV vaccination at home.This approach has its positive side, t. To. This eliminates the risk of infection with SARS patient or the flu.

vaccines against cervical cancer are relatively expensive, and their free introduction is possible only in some Russian cities and regions in which their acquisition funds were allocated from the federal budget (Moscow, Samara, Tver, Yakutia, the Khanty-Mansi Autonomous Area and MoscowRegion).In other cases, they are carried out after pre-payment.

Inoculations performed HPV vaccines which do not contain live virus, and thus the risk of complications from them is low.In most cases, they do not cause violent immune reactions and are expressed in local manifestations.

Local adverse reactions to Gardasil and Cervarix:

These adverse reactions do not require specific treatment and resolved spontaneously within a few days.Their severity may be different, and, in the case of getting the drug into the subcutaneous fat layer at the injection site may form a bump (it resolves over several weeks).

Common adverse reactions to Gardasil and Cervarix:

These adverse reactions are quickly on their own.In severe headache and fever can take painkillers or antipyretics (Nise, Nurofen, Nimesulide or paracetamol).

extremely rare introduction of HPV vaccines may be accompanied by severe allergic reactions (angioedema, urticaria, anaphylactic shock).When addiction to such practices recommend taking antihistamines II and III generation (Telfast, Aerius, Fenistil) a few days before vaccination.

During studies of HPV vaccination was highly effective in protecting against infection with those strains against which the drugs have been developed Gardasil and Cervarix.The maximum duration of these vaccines from the date of last booster is about 8 years.After vaccination, the risk of infection by the HPV types against which it is directed, is reduced to zero, but from its exposure to other species are not protected.

introduction of Gardasil or Cervarix significantly reduces the likelihood of developing malignant transformation of cells of the mucous layer of the cervix, but does not guarantee 100% protection against cancer, t. To. These vaccines can prevent infection with two oncogenic types (16 and 18) HPV.About 30% of these cancers are provoked by other species of the virus and vaccination against them have not been developed.

decide whether vaccination against cervical cancer will help our article and the advice of your gynecologist.According to research, the introduction of Gardasil and Cervarix provides production of the required number of antibodies in 99% of cases.These vaccines approved by WHO and the European Union and included in the schedule of vaccination in most developed countries.

to vaccination against cervical cancer have repeatedly appealed cultural figures, arranged a variety of events.About one of them can be seen with the 23 minutes video program "Health" on March 7, 2010:

The program "Living Health" to discuss how to protect against cervical cancer.This question is relevant for women:
