Cervarix is a vaccine against certain types of cancer-causing human papillomavirus (HPV).

Contents

Cervarix is designed to prevent infection from HPV types 16 and 18, that cause about 70% of cervical cancer cases. [6] These types also cause most HPV-induced genital and head and neck cancers. Additionally, some cross-reactive protection against virus strains 45 and 31 were shown in clinical trials. [7] Cervarix also contains AS04, a proprietary adjuvant that has been found to boost the immune system response for a longer period of time. [8]

Cervarix is manufactured by GlaxoSmithKline. An alternative product, from Merck & Co., is known as Gardasil. [6] Cervarix was voluntarily taken off of the market in the US in 2016 due to low demand. [9]

Medical uses

HPV is a virus, usually transmitted sexually, which can cause cervical cancer in a small percentage of those women genital infected. Cervarix is a preventative HPV vaccine, not therapeutic. HPV immunity is type-specific, so a successful series of Cervarix shots will not block infection from cervical cancer-causing HPV types other than HPV types 16 and 18 and some related types, so experts continue to recommend routine cervical Pap smears even for women who have been vaccinated. Vaccination alone, without continued screening, would prevent fewer cervical cancers than regular screening alone. [10] [11]

Cervarix is indicated for the prevention of the following diseases caused by oncogenic HPV types 16 and 18: cervical cancer, cervical intraepithelial neoplasia (CIN) grade 2 or worse and adenocarcinoma in situ, and CIN grade 1. In the United States, Cervarix is approved for use in females 10 through 25 years of age [12] while in some other countries the age limit is at least 45. [13]

As of September 2009, Cervarix was shown to be effective 7.3 years after vaccination. [14]

Administration

Immunization with Cervarix consists of 3 doses of 0.5-mL each, by intramuscular injection according to the following schedule: 0, 1, and 6 months. [6] The preferred site of administration is the deltoid region of the upper arm. [6] Cervarix is available in 0.5-mL single-dose vials and prefilled TIP-LOK syringes. [12]

Limitations of effectiveness

Cervarix does not provide protection against disease due to all HPV types, nor against disease if a woman has previously been exposed through sexual activity and protection may not be obtained by all recipients. [12] It is therefore recommended that women continue to adhere to cervical cancer screening procedures.[ citation needed ]

Adverse effects

In common with some other prefilled syringe vaccination products, the tip cap and the rubber plunger of the needleless prefilled syringes contain dry natural latex rubber that may cause allergic reactions in latex sensitive individuals. [15] The vial stopper does not contain latex.

Ingredients

The active components of the vaccine are: [12] [16]

Biotechnology

Cervarix is created using the L1 protein of the viral capsid. L1 protein is in the form of non-infectious virus-like particles (VLPs) produced by recombinant DNA technology using a Baculovirus expression system which uses High Five Rix4446 cells derived from the insect Trichoplusia ni. The vaccine contains no live virus and no DNA, so it cannot infect the patient. [12]

History

The research findings that pioneered the development of the vaccine began in 1991 by The University of Queensland investigators Jian Zhou and Ian Frazer in Australia . Researchers at UQ found a way to form non-infectious virus-like particles (VLP), which could also strongly activate the immune system. Subsequently, the final form of the vaccine was developed in parallel, by researchers at Georgetown University Medical Center, the University of Rochester, the University of Queensland in Australia, and the U.S. National Cancer Institute. [17]

Clinical trials

Phase III trials have been conducted, including over 18,000 women from 14 countries in Asia-Pacific, Europe, Latin America and North America. [18]

As of 2009, the manufacturer was conducting a trial to compare the immunogenicity and safety of Cervarix with Gardasil. [19] Subsequent studies showed Cervarix generated higher antibody levels than Gardasil, the other commercially available HPV vaccine, upon testing seven months later, with twice the level for HPV type 16 and six times for HPV type 18. [20]

Society and culture

In the United Kingdom it was included in the national vaccination programme for teenage and pre-teenage girls aged 12–13 and 17–18 from September 2008 to August 2012. This caused some controversy since Cervarix was chosen over Gardasil, even though Gardasil protects against additional HPV types 6 and 11 (which cause genital warts). However, the efficacy of Cervarix is higher. [27]

Warts are non-cancerous viral growths usually occurring on the hands and feet but which can also affect other locations, such as the genitals or face. One or many warts may appear. They are distinguished from cancerous tumors as they are caused by a viral infection, such as a human papillomavirus, rather than a cancer growth.

<span class="mw-page-title-main">Cervical cancer</span> Cancer arising from the cervix

Cervical cancer is a cancer arising from the cervix or in the any layer of the wall of the cervix. It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. Early on, typically no symptoms are seen. Later symptoms may include abnormal vaginal bleeding, pelvic pain or pain during sexual intercourse. While bleeding after sex may not be serious, it may also indicate the presence of cervical cancer.

<span class="mw-page-title-main">Human papillomavirus infection</span> Human disease

Human papillomavirus infection is caused by a DNA virus from the Papillomaviridae family. Many HPV infections cause no symptoms and 90% resolve spontaneously within two years. In some cases, an HPV infection persists and results in either warts or precancerous lesions. These lesions, depending on the site affected, increase the risk of cancer of the cervix, vulva, vagina, penis, anus, mouth, tonsils, or throat. Nearly all cervical cancer is due to HPV, and two strains – HPV16 and HPV18 – account for 70% of all cases. HPV16 is responsible for almost 90% of HPV-positive oropharyngeal cancers. Between 60% and 90% of the other cancers listed above are also linked to HPV. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis.

<span class="mw-page-title-main">Genital wart</span> Sexually transmitted infection caused by certain types of human papillomaviruses

Genital warts are a sexually transmitted infection caused by certain types of human papillomavirus (HPV). They may be flat or project out from the surface of the skin, and their color may vary; brownish, white, pale yellow, pinkish-red, or gray. There may be a few individual warts or several, either in a cluster or merged together to look cauliflower-shaped. They can be itchy and feel burning. Usually they cause few symptoms, but can occasionally be painful. Typically they appear one to eight months following exposure. Warts are the most easily recognized symptom of genital HPV infection.

Anal cancer is a cancer which arises from the anus, the distal opening of the gastrointestinal tract. Symptoms may include bleeding from the anus or a lump near the anus. Other symptoms may include pain, itchiness, or discharge from the anus. A change in bowel movements may also occur.

Virus-like particles (VLPs) are molecules that closely resemble viruses, but are non-infectious because they contain no viral genetic material. They can be naturally occurring or synthesized through the individual expression of viral structural proteins, which can then self assemble into the virus-like structure. Combinations of structural capsid proteins from different viruses can be used to create recombinant VLPs. Both in-vivo assembly and in-vitro assembly have been successfully shown to form virus-like particles. VLPs derived from the Hepatitis B virus (HBV) and composed of the small HBV derived surface antigen (HBsAg) were described in 1968 from patient sera. VLPs have been produced from components of a wide variety of virus families including Parvoviridae, Retroviridae, Flaviviridae, Paramyxoviridae and bacteriophages. VLPs can be produced in multiple cell culture systems including bacteria, mammalian cell lines, insect cell lines, yeast and plant cells.

<span class="mw-page-title-main">HPV vaccine</span> Class of vaccines against human papillomavirus

Human papillomavirus (HPV) vaccines are vaccines that prevent infection by certain types of human papillomavirus (HPV). Available HPV vaccines protect against either two, four, or nine types of HPV. All HPV vaccines protect against at least HPV types 16 and 18, which cause the greatest risk of cervical cancer. It is estimated that HPV vaccines may prevent 70% of cervical cancer, 80% of anal cancer, 60% of vaginal cancer, 40% of vulvar cancer, and show more than 90% effectiveness in preventing HPV-positive oropharyngeal cancers. They also protect against penile cancer. They additionally prevent some genital warts, with the quadrivalent and nonavalent vaccines that protect against HPV types HPV-6 and HPV-11 providing greater protection.

<span class="mw-page-title-main">Gardasil</span> Human papillomavirus vaccine

Gardasil is an HPV vaccine for use in the prevention of certain strains of human papillomavirus (HPV). It was developed by Merck & Co. High-risk human papilloma virus (hr-HPV) genital infection is the most common sexually transmitted infection among women. The HPV strains that Gardasil protects against are sexually transmitted, specifically HPV types 6, 11, 16 and 18. HPV types 16 and 18 cause an estimated 70% of cervical cancers, and are responsible for most HPV-induced anal, vulvar, vaginal, and penile cancer cases. HPV types 6 and 11 cause an estimated 90% of genital warts cases. HPV type 16 is responsible for almost 90% of HPV-positive oropharyngeal cancers, and the prevalence is higher in males than females. Though Gardasil does not treat existing infection, vaccination is still recommended for HPV-positive individuals, as it may protect against one or more different strains of the disease.

Bovine papillomaviruses (BPV) are a paraphyletic group of DNA viruses of the subfamily Firstpapillomavirinae of Papillomaviridae that are common in cattle. All BPVs have a circular double-stranded DNA genome. Infection causes warts of the skin and alimentary tract, and more rarely cancers of the alimentary tract and urinary bladder. They are also thought to cause the skin tumour equine sarcoid in horses and donkeys.
