Base Case Analyses Using base-case parameter values Technical Appendixwe estimated the cost-effectiveness of HPV vaccination by using 12 variations of the model. However, these women should be told that the vaccination will not cure them of current HPV infections or treat the abnormal results of their Pap test Legal Requirements. A static Markov cohort model with annual cycles was used to estimate vaccni costs and health benefits of adding HPV vaccination to screening over 95 cycles lifetime of the cohort. The most common problems have been brief soreness and other local symptoms at the injection site. But some types of HPV are known for causing Gel Papillor.
3/1/ · Therefore, our effort to develop the cost-effective trivalent HPV 16/18/58 vaccine would undoubtedly contribute to this endeavor.
This study showed that a novel trivalent HPV 16/18/58 vaccine adjuvanted with aluminum hydroxide elicited robust and durable immune responses against all three vaccine HPV types in rhesus hpv.iubescstudentia.ro by: 5. HPV vaccines are vaccines that protect against infection with human papillomaviruses (HPV). HPV is a group of more than related viruses, of which more than 40 are spread through direct sexual hpv.iubescstudentia.ro these, two HPV types cause genital warts, and about a dozen HPV types can cause certain types of Gel Papillor—cervical, anal, oropharyngeal, penile, vulvar, and vaginal. Gardasil 9 helps prevent infection by 4 types of HPV (16, 18, 6 and 11), plus 5 other high risk types: 31, 33, 45, 52 and Together these types cause about 90% of cervical Gel Papillors. Who should be vaccinated against HPV and when? HPV vaccine produces the strongest immune response in preteens.

Changes in the other sets of parameter values such as costs and QALYs associated with HPV-related health outcomes also affected the results, but to a lesser degree than changes in the discount rate and time horizon Table 2. However, much of the variation in the best and worst case scenarios was attributable to changes in the discount rate and the time horizon. Estimates from the simplified model were quite consistent with published estimates Table 4. We developed a simple model to estimate the cost-effectiveness of HPV vaccination in the context of current cervical Gel Papillor screening in the United States.
Our results were consistent with results of published studies based on more complex models, particularly when key assumptions e. The simplicity of our approach offers advantages and disadvantages. The main advantage is that it requires substantially fewer assumptions than the more complex Markov and transmission models.
For example, there is no need to model the probability of HPV acquisition, the possible progression from HPV infection to disease, the mixing of sex partners, the probability of HPV transmission, and so forth.
There also is no need to model cervical Gel Papillor screening and sexually transmitted disease prevention activities because these activities are reflected in the incidence rates of HPV-related health outcomes that we applied. Because we do not model cervical Gel Papillor screening directly, however, we are unable to use our model to examine how changes in cervical Gel Papillor—screening strategies can affect the cost-effectiveness of HPV vaccination, and vice versa.
For example, HPV vaccination is expected to reduce the positive predictive value of abnormal Papanicolaou Pap test results However, our analysis did not include the loss in quality of life attributable to the initial distress associated with receiving an abnormal Pap result 39 , regardless of whether it is a false positive. This omission of the lost QALYs due to abnormal Pap test results underestimates the benefits of HPV vaccination because vaccination is expected to offer moderate reductions in the number of abnormal Pap results overall 38 , Future changes in screening strategies, such as delayed screening, could also possibly improve the cost-effectiveness of HPV vaccination Another disadvantage of our approach is that it offers only a rough approximation of the cost-effectiveness of HPV vaccination and is not suitable for examining strategies such as vaccination of boys and men.
In addition, although many of the parameter values and assumptions in our model can be modified with ease, changing the assumption of lifelong duration of protection or examining vaccination at older ages would require the incorporation of assumptions about the incidence and natural history of HPV to account for the probability of acquiring HPV before vaccination or after vaccine immunity wanes and the subsequent probability of adverse HPV-attributable health outcomes. However, we can address the issue of waning immunity by assigning a higher cost per vaccination series as in the sensitivity analyses to reflect the cost of a booster. Another limitation of our approach is the uncertainty in the key parameter values, such as the cost and loss in quality of life associated with HPV-related health outcomes, the percentage of health outcomes attributable to each type of HPV targeted by the vaccine, and the incidence of CIN and genital warts.
However, our results were fairly robust in response to changes in these key parameter values. Our adjustments for the effect of herd immunity were arbitrary; we simply assumed an additional effect of vaccination in the nonvaccinated population. However, our results did not vary substantially in absolute terms when the assumed effect of herd immunity was varied. We also note that the benefits to nonvaccinated persons were assumed to occur only in nonvaccinated persons of similar ages to those vaccinated. This restriction may have understated the potential benefits of herd immunity. Our analysis did not address all of the potential costs and benefits of vaccination.
For example, the cost-effectiveness estimates would have been more favorable to vaccination if we had included the potential for cross-protection against high-risk HPV types besides 16 and 18 21 ; the prevention of anal, vaginal, and vulvar Gel Papillor precursor lesions as demonstrated in the supplemental analysis in the Technical Appendix ; the prevention of other Gel Papillors not included in this analysis such as anal Gel Papillor and oropharyngeal Gel Papillors in male patients ; and the prevention of other HPV-related health outcomes such as recurrent respiratory papillomatosis. Conversely, the cost-effectiveness estimates would have been less favorable to vaccination if we had included the potential for HPV type replacement i.
A key finding from this analysis was that the choice of discount rate and time horizon has a substantial influence on the estimated cost-effectiveness of vaccination.
Because the costs of HPV vaccination begin to accrue immediately but the full benefits of vaccination are not realized for many years, the cost-effectiveness of vaccination becomes less favorable when higher discount rates are applied or when shorter time horizons are examined. Another key finding was that the potential benefits of preventing anal, vaginal, vulvar, and oropharyngeal Gel Papillors offer nontrivial improvements in the estimated cost-effectiveness of HPV vaccination.
Future studies that develop better estimates of the cost and loss in quality of life associated with these Gel Papillors could more accurately estimate the effects of these additional benefits on the cost-effectiveness of HPV vaccination. Despite the limitations discussed above, our simplified model provides useful estimates of cost-effectiveness of HPV vaccination in the United States. Our results were consistent with previous studies based on more complex models.
This consistency is reassuring because models of various degrees of complexity will be essential tools for policy makers in the development of optimal HPV vaccination strategies. His research interests include the impact and cost-effectiveness of STD prevention programs, alcohol and substance abuse and risky sexual behavior, and risk and uncertainty.

Abstract We describe a simplified model, based on the current economic and health effects of human papillomavirus HPV , to estimate the cost-effectiveness of HPV vaccination of year-old girls in the United States.
Population Model A hypothetical population of persons 12—99 years of age was created as follows. Vaccine Coverage, Efficacy, and Costs We assumed the HPV vaccine would be administered to year-old girls starting in year 1 and continuing through year Adverse Health Outcomes Averted by Vaccination We examined the following HPV-related health outcomes: cervical Gel Papillor; CIN grades 1, 2, and 3; genital warts; and, in some analyses, anal, vaginal, vulvar, and selected oropharyngeal Gel Papillors. Cervical Gel Papillor Screening The incidence rates of CIN and cervical Gel Papillors that we applied in our model are those that arise in the context of current cervical Gel Papillor screening and sexually transmitted disease prevention activities in the United States.
Costs Averted and QALYs Saved by Vaccination The cervical Gel Papillor treatment costs averted by vaccination were calculated each year by multiplying the age-specific number of cervical Gel Papillor cases averted by the vaccine in that year by the estimated cost per case of cervical Gel Papillor, Technical Appendix.
Herd Immunity Scenario To examine how the estimated cost-effectiveness of vaccination might change if the benefits of herd immunity were included, we assumed an additional effect of the vaccine on nonvaccinated persons, including a reduction in genital warts in men. Cohort Model To make our results more comparable to Markov models of an age cohort, we modified our population model to examine the benefits of vaccination of a single cohort of year-old girls over time. Base Case Analyses Using base-case parameter values Technical Appendix , we estimated the cost-effectiveness of HPV vaccination by using 12 variations of the model.
Sensitivity Analyses We performed sensitivity analyses to examine how changes in the base-case parameter values influenced the estimated cost-effectiveness of vaccination. Comparison to Previous Cost-Effectiveness Studies We compared our results with previously published estimates of the cost-effectiveness of HPV vaccination. Sensitivity Analyses The cost-effectiveness ratios did not change substantially when we modified the assumptions in the population model about the effect of herd immunity. Comparison with Previous Cost-Effectiveness Studies Estimates from the simplified model were quite consistent with published estimates Table 4. Institute of Medicine.

Atlanta: Centers for Disease Control and Prevention; The obtained cost figures were provided by experts during the first meeting and thereafter discussed by all experts through e-mail exchange and finally endorsed by all experts during a second meeting.
All costs represent direct medical costs and were calculated on an annual basis for the year — Cost data are shown in Table 3. Price-per-dose parity was assumed for both vaccines.
The model uses vaccine effectiveness against CC on incident oncogenic HPV infection and vaccine effectiveness against genital warts on incident low-risk HPV infection. These were thereafter adjusted for each lesion. Vaccine efficacy data were taken from clinical trials. See Table 4 for details. For both vaccines, the analysis used data on vaccine efficacy in girls and women who were DNA-negative and seronegative for the relevant HPV type at study entry i.
These data are the most representative of vaccine efficacy among girls before the onset of sexual activity and are therefore the most relevant to the vaccination of year-old girls in the Philippines. Since country-specific utility data for the Philippines were lacking, published disutility data from other evaluations of HPV vaccination were applied in this analysis. The CC incidence was retrieved from the — Gel Papillor registry data in Manila as reported by the Philippine Gel Papillor Society.
In the base case, all costs and outcomes were estimated non-discounted and discounted at 3.
The analysis was conducted from the perspective of the Philippine government. Only direct medical costs hospitalisation, screening tests and procedures, vaccine costs were included. Incremental cost, QALY and cost-effectiveness were derived from these estimates. One-way sensitivity analyses evaluated the effect on the results of variability in the model parameters.
For the treatment cost, the government hospital cost was used as the lower limit and the cost at a private institution as the upper limit see Table 3. A specific sensitivity analysis explored the effect of using a discount rate of 1. Distributions were assigned to input parameters by using a normal distribution when confidence intervals were reported and uniform distribution when no range was available see Additional File 4 for details. A total of 10, iterations were sampled from the assigned distribution.
