NEJM: HPV vaccine is effective in preventing cervical cancer.

March 20, 2020 /--- According to a large study published in the journal New England Journal of Medicine by researchers at the Karolinska Institute in Sweden, women who have been vaccinated against HPV have a significantly lower risk of developing cervical cancer, the most significant positive effect for young women.
"This is the first time that HPV vaccination has been shown at the population level that HPV vaccination can not only prevent cell mutations that can lead to cervical cancer, but also prevent the actual occurrence of indulging cervical cancer."
's something we've long suspected.
(Photo: www.pixabay.com) HPV (human papillomavirus) is a type of virus that usually causes warts and various types of cancer, including cervical cancer, which kills more than 250,000 women worldwide each year.
more than 100 countries have implemented national vaccination programmes for HPV.
previous studies have shown that the HPV vaccine can prevent HPV infection, warts and pre-cancer cervical lesions that can develop into cervical cancer.
, however, there is still a lack of large population-based research.
study, researchers tracked about 1.7 million women between the ages of 10 and 30 over 11 years.
, more than 500,000 people have been vaccinated against HPV, most of whom have been diagnosed before the age of 17.
Compared to 538 unvaccinated women, an analysis by 47 and 94 female researchers per 100,000 people showed that HPV vaccination was associated with a significant reduction in the risk of cervical cancer, and that girls who were vaccinated before the age of 17 had an 88 percent lower risk of cervical cancer.
the study showed that women who were vaccinated between the ages of 17 and 30 had a half lower risk of cervical cancer than unvaccinated women.
"Girls who are vaccinated at a young age seem to be given more protection, probably because they are less likely to be infected with HPV, and given that HPV vaccination has no therapeutic effect on past infections," said Pär Sparén, a researcher at the university.
overall, our study shows that HPV vaccination can significantly reduce the risk of cervical cancer, especially when completed early," PärSparén said.
"our data strongly support the continuation of HPV vaccinations for children and adolescents through national vaccination programmes.
