VPH, VIRUS DEL PAPILOMA HUMANO Y VACUNAS, ACTUALIZACIÓN !
HPV, HUMAN PAPILLOMA VIRUS AND VACCINES, UPDATE !
===================
Hola amigos de la red DERMAGIC EXPRESS hoy te voy a poner una actualización del VIRUS DEL PAPILOMA HUMANO, VPH.
Posteriormente en el año de 1974, el medico y virologo Aleman Harald zur Hausen fue el primero en proponer que el virus del VPH podría estar vinculado o relacionado con cancer cervical en humanos, lo cual fue cierto y le valió para ganar el Premio Nobel de Medicina en el año 2008.
A partir de la década de los 80 y años siguientes, se investigo los distintos tipos de VPH, aislándolos y clasificándolos, siendo los primeros, los VPH1, VPH6, VPH11, VPH16 y VPH18, este ultimo asociado a cancer cervical.
A.- Es el virus de transmisión sexual más común en el mundo.
B.- Cerca del 80% de las personas sexualmente activas lo contraerán alguna vez.
A.- ALTO RIESGO: El VPH16 y VPH18 siguen siendo los más comunes en cuanto a malignidad representando entre el 70 - 75% de los casos de cáncer cervicouterino a nivel mundial; otros sitios de localización son: ano, vulva, vagina, pene y orofaringe.
C.- En 2006 la primera vacuna fue aprobada en Estados Unidos, por los laboratorios: Merck & Co, (EE.UU.), MSD en Europa y Sanofi-Pasteur, con el nombre comercial de GARDASIL (tetravalente), la cual protege contra los VPH6, VPH11, VPH16, y VPH18 para cáncer cervical, y VPH6 y VPH11 para verrugas genitales.
D.- En el año 2007 fua aprobada por la FDA la VACUNA CERVARIX (bivalente) del laboratorio GlaxoSmithKline (GSK, Reino Unido), la cual protege contra los virus VPH16, y VPH18, para evitar fundamentalmente el cáncer cervical, con una cobertura de aproximadamente del 66%, y a la cual también se la atribuye "ALGO" de protección cruzada contra otros tipos de alto riesgo.
"En un periodo de 23 a 25 años aparecieron unas 120 CEPAS nuevas DEL VIRUS PAPILOMA HUMANO V.P.H, quizá este aumento cabalgante fue lo que llevo a los laboratorios a FABRICAR VACUNAS para esta enfermedad, la experiencia con las mismas ha sido CONTROVERSIAL", pero el hecho de que protejan contra los dos tipos de VPH mas oncogenicos es un "SIGNO POSITIVO."
En este enlace encuentras la publicación ORIGINAL del VIRUS DEL VPH Y SU COMPORTAMIENTO EN EL MUNDO (1999); es importante que te la leas, para que aprendas como ha evolucionado el comportamiento de este virus en la población mundial desde ese año hasta nuestros días.
NOTA: Actualmente estas vacunas tienen un costo de 250$ dolares Americanos en Venezuela.
Saludos a todos!!!Dr. José Lapenta R.
=================
Hello friends of the DERMAGIC EXPRESS network, today I'm going to give you an UPDATE ON THE HUMAN PAPILLOMAVIRUS (HPV).
This article began more than 20 years ago with a publication published online in 1999, entitled "HPV AND ITS BEHAVIOR IN OUR WORLD." I discussed the behavior of this virus in 43 countries, and the emergence of vaccines against it was still far from complete.
From 2017 to 2023, I updated it, and today, in 2025, I'm bringing you two updated versions of the HPV virus: the one you're reading and the link at the end of this article, published under the name HUMAN PAPILLOMA VIRUS (HPV) UPDATE (2025)."
1.) HISTORY OF THE HPV VIRUS:
The first to describe the HPV virus was the American virologist and pathologist Richard Shope in 1933, which he did in rabbit skin warts.
Later, in 1974, the German physician and virologist Harald zur Hausen was the first to propose that the HPV virus could be linked or related to cervical cancer in humans, which proved true and earned him the Nobel Prize in Medicine in 2008.
Beginning in the 1980s and following years, the different types of HPV were investigated, isolated, and classified. The first were HPV1, HPV6, HPV11, HPV16, and HPV18, the latter being associated with cervical cancer.
2.) CHARACTERISTICS OF THE VIRUS:
The human papillomavirus (HPV) is a double-stranded DNA virus belonging to the Papillomaviridae family.
It is characterized by being a small, human-specific virus that causes multiple skin and mucous membrane infections, including warts and cervical intraepithelial neoplasia in women, many of which progress to cancer.
3.) IMPORTANCE:
The importance of this virus is based on three facts:
A. It is the most common sexually transmitted virus in the world.
B. About 80% of sexually active people will contract it at some point.
C.- Some HPV genotypes, such as HPV16 and HPV18, among others, are highly oncogenic (carcinogenic), and are responsible for the majority of cervical cancers.
4.) CLASSIFICATION: (YEAR 2017-2023):
As of 2023, there are approximately 200 types of HPV, of which 51 species affect the genital mucosa. They are classified as follows:
A.)Mostcarcinogenic types:
B.) Probable high risk: HPV26, HPV53, and HPV66.
C.) Low carcinogenic risk: HPV6, HPV11, HPV40, HPV42, HPV43,HPV HPV44,
5.) CURRENT CLASSIFICATION (YEAR 2025):
In 2012, the International Association for Cancer Research decided to modify this classification, and today only two (2) types are considered: HIGH RISK and LOW RISK. At this link, you will find the update on the HPV, HUMAN PAPILLOMA VIRUS, UPDATE (2025). with more information and bibliographic references.
A.- HIGH RISK: HPV16 and HPV18 continue to be the most common types of malignancy, representing between 70-75% of cervical cancer cases worldwide. Other sites include: anus, vulva, vagina, penis, and oropharynx.
B. Between 15 and 20% of additional malignancy cases are represented by the HIGH-RISK genotypes: HPV31, HPV33, HPV45, HPV52, and HPV58, which together contribute to an additional 15-20% of cases.
C. The other genotypes that stand out as HIGH-RISK, accounting for 5% of cases, are: HPV35, HPV59, HPV39, HPV56, HPV51, HPV68, HPV73, HPV26,
D.- Regarding the LOW-RISK genotypes, HPV6 and HPV11 are the most frequently reported in recurrent respiratory papillomatosis and anogenital warts, NOT ASSOCIATED WITH CANCER.
It was decided to include the MODERATE RISK subtypes in the HIGH RISK group, based on the scientists' assumption that these would eventually evolve into MALIGNANCY.
All of this you are reading led laboratories to search for and create VACCINES to protect the world's population from the spread of this VIRUS, 99.9% of which is acquired through sexual transmission.
6.) HISTORY OF THE CREATION OF VACCINES:
A.- In the 1980s, research into the creation of a vaccine began after the link between the HPV virus and cervical cancer was discovered.
B.- In 1991, Ian Fraser and Jian Zhou (University of Queensland, Australia) developed a technology to create virus-like particles (VLPs), a fundamental element for the possible creation of a VACCINE.
These particles (VLPs) were created through genetic engineering with the aim of stimulating the immune system, without containing infectious viral genetic material.
C.- In 2006, the first vaccine was approved in the United States by the laboratories: Merck & Co. (USA), MSD in Europe, and Sanofi-Pasteur, under the brand name GARDASIL (tetravalent). It protects against HPV6, HPV11, HPV16, and HPV18 for cervical cancer, and HPV6 and HPV11 for genital warts.
D.- In 2007, the FDA approved the CERVARIX (bivalent) vaccine from GlaxoSmithKline (GSK, United Kingdom). It protects against the HPV16 and HPV18 viruses, primarily to prevent cervical cancer, with a coverage of approximately 66%. It is also attributed with "SOME" cross-protection against other high-risk types.
E.) In 2014-2015, the GARDASIL-9 VACCINE (nine-valent) was approved. This is a broader version of the classic GARDASIL vaccine, offering protection against the following viruses: HPV6, HPV11, HPV16, HPV18, HPV31, HPV33, HPV45, HPV52, and HPV58. This vaccine offers greater coverage (90%) against high-risk HPV types for cervical cancer and warts.
7.) SIDE EFFECTS OF THE VACCINES:
The most common adverse effects, which are usually transient and self-limiting, are:
A.- Local and mild:
- Pain.
- Erythema (redness) and swelling at the injection site.
- Headache.
- Dizziness.
B. Moderate to severe:
- Syncope and fainting: especially in adolescents, so it is recommended that the patient be observed for at least 15 minutes after administration to prevent secondary injuries in the event of fainting.
- Severe anaphylactic reactions can occur when there is a known allergy to vaccine components and are extremely rare.
- The incidence of syncope and local reactions has been reported more frequently with GARDASIL-9 (nine-valent) compared to the classic GARDASIL (four-valent).
- There is an ABSOLUTE contraindication to the administration of other vaccines when the patient has been known to experience severe reactions.
C. Adverse events following the 9-valent human papillomavirus vaccine (GARDASIL® 9) reported to the Vaccine Adverse Event Reporting System (VAERS), 2015-2024:
Events not listed on the product label:
- Postural orthostatic tachycardia syndrome.
- Eye movement disorders.
- Autoimmune thyroiditis.
- Postural abnormality.
There were also 57 reports of deaths, 18 of which were in pregnant women, but the neurological characteristics or features lacked compelling etiological patterns, so the VAERS system concludes that the vaccine is "safe."
But if you want to delve deeper into what has happened with these vaccines, here is the link to the publication "POST-VACCINATION SYNDROME WITH GARDASIL AND CERVARIX" (2017), which completely "shows" the other "face" of the VAERS system from 2015 to 2024.
8.) CONCLUSION:
"Over a period of 23 to 25 years, some 120 new STRAINS OF THE HUMAN PAPILLOMAVIRUS (HPV) appeared. Perhaps this dramatic increase was what led laboratories to manufacture vaccines for this disease. Experience with these vaccines has been CONTROVERSIAL," but the fact that they protect against the two most oncogenic HPV types is a "POSITIVE SIGN."At this link, you'll find the original publication "HPV VIRUS AND ITS BEHAVIOR IN THE WORLD" (1999). It's important to read it to learn how the behavior of this virus has evolved in the global population from that year to the present.
NOTE: These vaccines currently cost $250 in Venezuela.
Greetings to all!!!
