For several years, human papillomavirus (HPV) vaccination following the removal of a portion of the cervix due to precancerous lesions was considered an effective option to reduce the risk of recurrence. Some studies even suggested a reduction of more than 50%. However, these conclusions were controversial, as they were based on studies that raised significant questions regarding the methodology used.
To Vaccinate or Not After Cervical Cancer Treatment? The Final Word
New data challenge these conclusions. A key meta-analysis, published in late 2024 in the scientific journal PLOS ONE, re-evaluated the issue with a more rigorous methodology. It selected only high-quality prospective clinical trials. The results show no significant benefit from HPV vaccination after local surgical treatment.
These findings are reinforced by initial data from a large Dutch trial, presented in November 2024 at the International Papillomavirus Society (IPVC) congress in Edinburgh. They found no significant protective effect of post-treatment vaccination.
The final blow comes from the most conclusive study to date: the NOVEL trial, a prospective, randomized, and double-blind study (the “top” of scientific methodology). Preliminary results were presented at the European Gynaecological Oncology Congress (EGO) in Rome, which recently concluded.
The NOVEL trial included 1,100 patients immediately after treatment for high-grade lesions or adenocarcinoma in situ (an early form of cervical cancer, limited to glandular cells without invasion of deep tissues). These women were randomly assigned to a group receiving the HPV vaccine and a placebo group, with rigorous follow-up over two years.
The verdict? There is no therapeutic benefit from HPV vaccination after local surgical treatment, neither for preventing persistent HPV infection nor for reducing the risk of recurrent cervical lesions.
Post-Treatment HPV Vaccination Is Needless
These results confirm that only vaccination before the age of 14 can prevent precancerous lesions and cervical cancer. Thus, post-treatment vaccination should not be recommended, according to the Société Française de Colposcopie et de Pathologie Cervico-Vaginale. The debate is closed.
In technical terms, a ”treatment by conization of high-grade intraepithelial lesions CIN2/3.”
Understanding HPV and Cervical Cancer
Human papillomavirus (HPV) is a common virus transmitted through sexual contact. According to https://www.sante.fr/decryptage/nos-reponses/quels-sont-les-benefices-et-les-risques-du-vaccin-contre-les-papillomavirus
, most men and women are infected during their lives, often without knowing it.While the infection usually clears on its own, certain types of HPV can lead to various genital cancers, including cervical cancer.
The Role of Cervical Screening
Even with HPV vaccination, regular cervical screening remains crucial. As stated in https://sante.journaldesfemmes.fr/fiches-sante-du-quotidien/2597585-vaccin-papillomavirus-hpv-risques-effets-secondaires/
, “Vaccination against HPV does not replace cervical cancer screening by Pap smear, which remains essential from the age of 25, whether you are vaccinated or not.”
Long-Term Impact of HPV Vaccination
The full impact of HPV vaccination on cervical cancer rates will take time to measure. https://vaccination-info-service.fr/content/download/1577/17217/version/1/file/FactsHPVVF.pdf
notes that “The impact of vaccination on cervical cancers can only be measured several decades after the introduction of vaccines due to the long delay between infection with oncogenic HPVs and the occurrence of cancer (most often between 10 and 30 years).”
HPV Vaccination After Cervical Cancer Treatment: Your Questions Answered
For years, the question of whether too get an HPV vaccine after treatment for precancerous cervical lesions has been a topic of debate. Recent research provides more clarity. This Q&A will address common questions and provide guidance based on the latest scientific evidence.
Is HPV Vaccination Effective After Cervical Cancer Treatment?
No,recent studies indicate that HPV vaccination after local surgical treatment for high-grade lesions or early-stage cervical cancer (adenocarcinoma in situ) dose not provide a important therapeutic benefit. This means it doesn’t help in preventing persistent HPV infection or reducing the risk of recurrent cervical lesions.
Key Findings:
Meta-analysis (PLOS ONE,2024): A rigorous review of high-quality clinical trials showed no significant benefit from HPV vaccination after surgical treatment.
Dutch Trial (IPVC Congress, 2024): Data presented at the International Papillomavirus Society (IPVC) congress also found no significant protective effect of post-treatment vaccination.
* NOVEL Trial (ESGO Congress, 2025): This prospective, randomized, and double-blind study (the gold standard in research) involving 1,100 patients found no therapeutic benefit from HPV vaccination after local surgical treatment.
Why Was HPV Vaccination Previously Considered an Option After Treatment?
Earlier studies suggested a potential benefit, with some indicating a reduction of over 50% in recurrence risk. However, these studies were based on methodologies that raised questions. More recent and methodologically sound research has challenged these earlier conclusions.
What Does this Mean for Post-Treatment Care?
According to the Société Française de Colposcopie et de Pathologie Cervico-Vaginale, post-treatment HPV vaccination should not be recommended. The focus should be on vaccination before the age of 14 for preventative purposes and continued regular cervical screening.
What is HPV and How Does it Relate to Cervical Cancer?
Human papillomavirus (HPV) is a very common virus transmitted through sexual contact. Most people will be infected with HPV at some point in their lives, frequently enough without knowing it as the infection usually clears on its own. However, certain high-risk types of HPV can lead to various cancers, including cervical, anal, and oropharyngeal cancers.
What is Cervical Screening and Why is it Still Vital?
Cervical screening, typically through a Pap smear, is a way to detect precancerous changes in the cervix before they develop into cancer.Even if you have received the HPV vaccine, regular cervical screening is crucial. Guidelines generally recommend starting screening at age 25, and it remains essential whether you are vaccinated or not.
Long-Term Impact of HPV Vaccination on Overall Cervical Cancer Rates
The full impact of HPV vaccination on cervical cancer rates will take decades to measure. This is due to the long delay (10-30 years) between HPV infection and the potential growth of cancer. Continued monitoring and research are necessary.

What is Conization?
The article mentions “treatment by conization of high-grade intraepithelial lesions CIN2/3.” Conization is a surgical procedure where a cone-shaped piece of tissue is removed from the cervix.It is indeed commonly used to treat high-grade precancerous lesions (CIN2/3) to prevent them from progressing to cervical cancer.
