Alain Luxembourg, Susanne K Kjaer, Mari Nygard, Misoo C Ellison, Thomas Group, J Brooke Marshall, David Radley, Alfred Saah
The 9-valent human papillomavirus (HPV) (9vHPV) vaccine targets four HPV types (6/11/16/18) also covered by the quadrivalent HPV (qHPV) vaccine and five additional types (31/33/45/52/58). Vaccine efficacy to prevent HPV infection and disease was established in a Phase III clinical study in women 16-26years of age. A long-term follow-up (LTFU) study has been initiated as an extension of the Phase III clinical study to assess effectiveness of the 9vHPV vaccine up to at least 14years after the start of vaccination...

Cutaneous and genital warts are common dermatological conditions caused by the human papilloma virus (HPV). Although it is a benign condition, it causes disfigurement, has a tendency to koebnerize, and can be transmitted to others. This makes adequate and timely treatment important. There are several conventional treatments available with variable response. Topical and systemic immunotherapy has now found a significant place in the treatment of warts because of its nondestructive action, ease of use, and promising results...

The use of DNA vaccines has become an attractive approach for generating antigen-specific cytotoxic CD8(+) T lymphocytes (CTLs), which can mediate protective antitumor immunity. The potency of DNA vaccines encoding weakly immunogenic tumor-associated antigens (TAAs) can be improved by using an adjuvant injected together with checkpoint antibodies. In the current study, we evaluated whether the therapeutic effects of a DNA vaccine encoding human papilloma virus type 16 (HPV-16) E7 can be enhanced by combined application of an immune checkpoint blockade directed against the programmed death-1 (PD-1) pathway and secondary lymphoid tissue chemokine (SLC) also known as CCL21 adjuvant, in a mouse cervical cancer model...

An association between immune-mediated diseases and cervical pre-malignant and malignant lesions is described, having the human papillomavirus (HPV) infection a causal role. Related studies have been generally focused on systemic lupus erythematosus (SLE) patients, but relatively to other diseases, such as rheumatoid arthritis (RA), Sjögren's syndrome (SS) and systemic sclerosis (SSc), data has not been systematically evaluated. We conducted a systematic review analysis of the literature in PubMed, including articles published until March of 2015, in patients with RA, SS, SLE and SSc, to evaluate the frequency of HPV infection, cervical dysplasia and cervical cancer, and associated factors, with particular interest on the role of glucocorticoids and immunosuppressive treatment...

CONTEXT: Vaccination against the human papillomavirus (HPV) decreases risks of cancer and genital warts and the need for gynecologic procedures, yet nationwide vaccination rates are low. Previous surveys exploring this phenomenon have not included inputfrom nurses and medical assistants, who play integral roles in HPV vaccine delivery. OBJECTIVE: To understand perceptions of HPV vaccine delivery among physicians, nurses, and medical assistants in a large integrated health care system in Southern California...

BACKGROUND: Cervical cancer is the fourth most common cancer among females in the United Arab Emirates (UAE) with an estimated incidence of 7.4 per 100,000 persons per year. In March 2008, the Health Authority of Abu Dhabi launched a free school-based campaign to provide all female Emirati students aged 15-17 years in the emirate of Abu Dhabi with the human papillomavirus vaccine (HPVV). Despite the proven efficacy of the HPVV in clinical trials, there has been limited research exploring the acceptance of this vaccine within a conservative Islamic society...

This article examines the rise of the anti-vaccination movement, the proliferation of laws allowing parental exemptions to mandatory school vaccines, and the impact of the movement on immunization rates for all vaccines. It uses the ongoing debate about the Human Papillomavirus (HPV) vaccine as an example to highlight the ripple effect and consequences of the anti-vaccine movement despite robust evidence of the vaccine's safety and efficacy. The article scrutinizes how state legislatures ironically promote vaccination while simultaneously deferring to the opposition by promulgating broad opt-outs from mandatory vaccine laws...

Granulocyte macrophage-colony stimulating factor (GM-CSF) is a potent immunomodulatory cytokine that is known to facilitate vaccine efficacy by promoting the development and prolongation of both humoral and cellular immunity. In the past years we have generated a novel codon-optimized GM-CSF gene as an adjuvant. The codon-optimized GM-CSF gene significantly increased protein expression levels in all cells tested and helped in generating a strong immune responses against HIV-1 Gag and HPV-associated cancer. Here, we review the literature dealing with the adjuvant activity of GM-CSF both in animal models and clinical trials...

BACKGROUND: Despite recommendations that 11-12-year-olds receive the full three-shot Human papillomavirus (HPV) vaccine series, national HPV immunization coverage rates remain low. Disparities exist, with Blacks and Latinos being less likely than Whites to complete the series. We aimed to identify and compare barriers to HPV immunization perceived by healthcare providers, Black and Latino adolescents, and their caregivers to inform a clinic-based intervention to improve immunization rates...

Safe and effective human papillomavirus (HPV) vaccines have been available and recommended for adolescents for a decade in the United States, yet vaccination rates remain suboptimal. School entry requirements have increased uptake of other vaccines for adolescents and made coverage more equitable. However, only 3 jurisdictions require HPV vaccine for school. We summarize the current status of HPV vaccine requirements and discuss the rationales for and against these policies. The rationales for requirements include HPV vaccine efficacy and safety, effectiveness of requirements for increasing vaccine uptake and making it more equitable, and use of requirements as "safety nets" and to achieve herd immunity...

BACKGROUND: Cervical cancer, a preventable disease, is the third leading cause of cancer morbidity and mortality in the Lao People's Democratic Republic (Lao PDR). Since many cervical cancers are linked to human papilloma virus (HPV) infection, vaccination against this virus may lead to a reduction in these types of cancer. The study described here is the first to compare the cost-effectiveness of different HPV vaccination options in Lao PDR. METHODS: A dynamic compartment model was created...

Human papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide. HPVs are oncogenic small double-stranded DNA viruses that are the primary causal agent of cervical cancer and other types of cancers, including in the anus, oropharynx, vagina, vulva, and penis. Prophylactic vaccination against HPV is an attractive strategy for preventing cervical cancer and some other types of cancers. However, there are few safe and effective vaccines against HPV infections. Current first-generation commercial HPV vaccines are expensive to produce and deliver...
