Cervical cancer, which is among the most common cancers in women, is increasing day by day. Because cervical cancer does not show symptoms in the early stages and develops slowly, routine screening programs are of great importance in terms of effective fight against this disease. HPV vaccine is required to protect against cervical cancer caused by sexually transmitted Human Papiloma Virus (HPV). However, false information about HPV vaccines in the society can lead to the lack of care about the vaccine and the spread of the disease. Associate Professor from the Department of Gynecological Oncology at Memorial Bahçelievler Hospital. Dr. Veysel Şal told what should be known about HPV vaccines.
Assoc. Dr. Veysel Şal made the following assessment:
Causes cancer in men
“Every year, approximately 500 thousand women are diagnosed with cervical cancer. HPV, which is generally transmitted through sexual contact and is responsible for almost all cervical cancers, usually does not show many symptoms in women and is highly contagious. Most women defeat the HPV virus they encounter at some point in their life with the help of their own body defense system. Some HPV viruses come out of this defense system strong and can cause cervical cancer. In men, it causes cancer of the mouth, pharynx, anus and penis and warts in the genital area.
Just because you've had it before doesn't mean you won't get caught again.
HPV virus is a virus that can disappear and re-infect. Unfortunately, immunity rates are not high after passing HPV. Therefore, vaccination has an important place among preventive measures.
13 facts you need to know about HPV vaccines
HPV vaccines have been in use all over the world for nearly 15 years.
When they first came out, there were vaccines that protect from 2 or 4 of the most common HPV types, but in recent years, 2 types have been released.
Our country has not yet received 9 vaccines. Quadruple vaccine is currently used in Turkey, but it is seen that the results of the quadruple and 4th vaccines are the same due to its cross-protection feature.
More than 100 countries routinely apply HPV vaccines as part of their national vaccination program.
The vaccine is recommended for men and women aged 9-15 years. Especially in this age period, 2 doses are given, at 0 and 6 months.
If you are over the age of 15, HPV vaccination is recommended until the age of 26.
A single dose is currently recommended for everyone under the age of 45 in the USA.
According to the European Union countries and the World Health Organization, 15 doses are recommended in the period after the age of 0, at 2, 6 and 3 months.
In general, there is no upper limit age, but the effectiveness of the vaccine decreases as age increases.
The presence or absence of HPV before vaccination is not important. Because 90% is a temporary infection, 10% is permanent. People who are HPV positive can also be vaccinated, it does not have to be negative. Therefore, there is no need to do any testing before making the HPV vaccine.
Vaccination is recommended for males aged 1-5 years. It can be done in certain situations after the age of 15, but it is not done for every man after the age of 15.
The HPV vaccine is a dead vaccine just like any other vaccine. The protein structure in the outer region of HPV is given as a vaccine, that is, dead cells are given and antibodies are created against it.
In a study conducted on a group with pre-cancerous lesions due to HPV, some of the group were vaccinated after treatment, while the other part was not, and it was observed that HPV cancer recurrence was approximately 3 times less in the vaccinated group. For this reason, it has also been proven that HPV vaccine reduces the risk of recurrence of lesions. “
