Once a vaccine is scientifically validated, it must be produced at a scale that can enable herd immunity (which can result from either vaccination or previous infection) on a global scale. However, carrying out the test annually was more cost effective than on a semi-annual basis. The models estimated that more than 1 billion people would be willing to spend US$25 for TB vaccination if the vaccine efficacy was 75% and the vaccine was effective for 10 years.
The study showed that at the moderate vaccine efficacy of 50%, for every 1000 vaccinated homeless persons, BCG vaccination would save one life, corresponding to a gain of 12 life-years through prevention of active TB cases. In the second study, Nettleman et al. While modeling the cost and effects, the authors also accounted for the R&D costs of new TB vaccines and concluded that even the assumed R&D costs were quadrupled and as such reflected in vaccine prices; vaccination using novel TB vaccines would still be cost effective in the long run. Vaccination against TB has advantages over skin testing in that the vaccinated persons have a reduced chance of getting the disease and that it may prevent disease caused by both drug-resistant and drug-sensitive microorganisms. The major cost composition of revaccination came from the fixed cost paid for nurses, who vaccinated children. What Is the Risk of Catching the Coronavirus on a Plane?
Until a new TB vaccine is developed, M. bovis bacille Calmette-Guérin (BCG) remains the only effective vaccine for TB (6,7). To comment please, Comments on Medscape are moderated and should be professional in tone and on topic. As summarized in Table 1 , in the oldest study by Stilwell,[21] the cost and health effects were discounted at the highest discount rate of 10%. Furthermore, limited access to healthcare service and unhealthy lifestyle made TB a serious and increasing problem. [23,24] Four studies carried out CEAs from the healthcare perspective (e.g., including direct medical cost and direct nonmedical cost).
[16] The justification for this study was that in crowded shelters many homeless people lived under conditions where TB surveillance was not feasible. Subsequently, the cost–effectiveness of TB vaccination was also investigated and compared with tuberculin skin testing, if a novel BCG-type vaccine effective in adults was developed.

This sub-Saharan country is categorized as a low-income country with a very high TB incidence (247 smear- positive cases per 100,000). Second, the study considered indirect costs incurred by parents and families of infected children and revealed that these costs constituted a large share of the societal costs. In addition, sensitivity analyses also revealed that the maximum benefits gained in two-way sensitivity analyses assuming 90% vaccine efficacy and 300% increased treatment cost compared to baseline were only US$23.6 million compared to the total BCG revaccination cost of US$32.1 million. https://www.canada.ca/.../page-2-bacille-calmette-guerin-vaccine.html The study by Nettleman et al. Consequently, Japan has met the criteria established by the IUATLD to discontinue universal BCG vaccination. © 2012 Expert Reviews Ltd. CBA: Cost-benefit analysis; CEA: Cost-effectiveness analysis; DOTS: Directly observed treatment, short course; PPD: Purified protein derivative. The authors combined an epidemiological analysis with a CEA to compare the current vaccination policy with the proposed extended policy. carried out another CEA of TB prevention strategies for physicians, who work in TB high-risk healthcare settings. It was suggested that investment in BCG revaccination in Japan would better be used for other health interventions that provide more health benefits.

| [5,13,15–17,19,20,23] Only two cost–effectiveness studies presented the costs per disability-adjusted-life-year (DALY).
Articles are reviewed in chronological order, from the earliest to the most recent.
The overall aim of the study is to assess how a future TB vaccine could influence the economic benefits by measuring the reduction of medical expenditure and productivity loss. Despite the fact that the study was done a long time ago, the results remain valid, at least in terms of selective BCG vaccination for high-risk TB groups in developed and countries with low incidence of TB.[28]. It is important to note that the results of this study might not be applicable for other high-incidence countries or other regions of the world. [19] The results showed that in Japan the treatment costs for a 2-year-old child infected with pulmonary TB is less than the cost of preventing a TB case through vaccination ($10,500 vs $35,950).
Indications for use in Europe and in developing countries]. It is important to note that the papers reviewed on BCG revaccination are more than a decade old. BCG is a live vaccine that has been processed so that it is not harmful to humans. BCG Vaccine for percutaneous use, is an attenuated, live culture preparation of the Bacillus of Calmette and Guerin (BCG) strain of Mycobacterium bovis.1 The TICE® strain used in this BCG Vaccine preparation was developed at the University of Illinois from a strain originated at the Pasteur Institute.The medium in which the TICE® BCG organism is grown for preparation of the freeze-dried cake is composed of the following ingredients… [13,19,20,23] Only two studies measured the cost spent to prevent DALY.
In the CBA, the baseline benefit–cost ratio was 0.13 showing that economic costs exceeded the benefits. Revaccination efficacy was assumed to be the same as the at-birth efficacy. No writing assistance was utilized in the production of this manuscript. BCG vaccination can cause a false positive Mantoux test, although a very high-grade reading is usually due to active disease.
