Valuing the Cost of Improving Chilean Primary Vaccination: a Cost Minimization Analysis of a Hexavalent Vaccine
Olivera et al. BMC Health Services Research (2020) 20:295 https://doi.org/10.1186/s12913-020-05115-7 RESEARCH ARTICLE Open Access Valuing the cost of improving Chilean primary vaccination: a cost minimization analysis of a hexavalent vaccine Ignacio Olivera1, Carlos Grau1, Hugo Dibarboure2, Juan Pablo Torres3, Gustavo Mieres1, Luis Lazarov1, Fabián P. Alvarez4 and Juan Guillermo López Yescas5* Abstract Background: The phased withdrawal of oral polio vaccine (OPV) and the introduction of inactivated poliovirus vaccine (IPV) is central to the polio ‘end-game’ strategy. Methods: We analyzed the cost implications in Chile of a switch from the vaccination scheme consisting of a pentavalent vaccine with whole-cell pertussis component (wP) plus IPV/OPV vaccines to a scheme with a hexavalent vaccine with acellular pertussis component (aP) and IPV (Hexaxim®) from a societal perspective. Cost data were collected from a variety of sources including national estimates and previous vaccine studies. All costs were expressed in 2017 prices (US$ 1.00 = $Ch 666.26). Results: The overall costs associated with the vaccination scheme (4 doses of pentavalent vaccine plus 1 dose IPV and 3 doses OPV) from a societal perspective was estimated to be US$ 12.70 million, of which US$ 8.84 million were associated with the management of adverse events related to wP. In comparison, the cost associated with the 4-dose scheme with a hexavalent vaccine (based upon the PAHO reference price) was US$ 19.76 million. The cost of switching to the hexavalent vaccine would be an additional US$ 6.45 million. Overall, depending on the scenario, the costs of switching to the hexavalent scheme would range from an additional US$ 2.62 million to US$ 6.45 million compared with the current vaccination scheme. -

Tasked by the Secretary-General, the Department of Operational Support (DOS) is leading a coordinated, UN-system-wide effort to ensure the availability of vaccine to UN personnel, their dependents and implementing partners. The roll-out of the UN System-wide COVID-19 Vaccination Programme (the “Programme”) for UN personnel will provide a significant boost to the ability of personnel to stay and deliver on the Organization's mandates, to support beneficiaries in the communities they serve, and to contribute to our on-going work to recover better together from the pandemic. Information about the Programme is available at: https://www.un.org/en/coronavirus/vaccination ABOUT THE VACCINATION CERTIFICATE Upon administration of the requisite vaccine dosage, a certificate of vaccination is generated through the Programme’s registration platform (the “Platform”). The certificate generated by the Platform uses a standardized format, similar to the one used by the WHO in its “International Certificate of Vaccination or Prophylaxis” (Yellow) vaccination booklet. Note: This certificate may not dispense with travel restrictions put in place by the country(ies) of destination. As the nature of the pandemic continues to rapidly evolve, it is highly advisable to check the latest travel regulations. -
Global Dynamics of a Vaccination Model for Infectious Diseases with Asymptomatic Carriers

Box 812 Yaounde, Cameroon 1;2;3; Jean Lubuma and Berge Tsanou ∗ Department of Mathematics and Applied Mathematics University of Pretoria, Pretoria 0002, South Africa (Communicated by Abba Gumel) Abstract. In this paper, an epidemic model is investigated for infectious dis- eases that can be transmitted through both the infectious individuals and the asymptomatic carriers (i.e., infected individuals who are contagious but do not show any disease symptoms). We propose a dose-structured vaccination model with multiple transmission pathways. Based on the range of the explic- itly computed basic reproduction number, we prove the global stability of the disease-free when this threshold number is less or equal to the unity. Moreover, whenever it is greater than one, the existence of the unique endemic equilibrium is shown and its global stability is established for the case where the changes of displaying the disease symptoms are independent of the vulnerable classes. Further, the model is shown to exhibit a transcritical bifurcation with the unit basic reproduction number being the bifurcation parameter. The impacts of the asymptomatic carriers and the effectiveness of vaccination on the disease transmission are discussed through through the local and the global sensitivity analyses of the basic reproduction number. Finally, a case study of hepatitis B virus disease (HBV) is considered, with the numerical simulations presented to support the analytical results. -

The Hepatitis B Vaccine Is the Most Widely Used Vaccine in the World, with Over 1 Billion Doses Given
Hepatitis B Vaccine Protect Yourself and Those You Love What is Hepatitis B? Hepatitis B is the most common serious liver infection in the world. It is caused by the hepatitis B virus (HBV), which attacks liver cells and can lead to liver failure, cirrhosis (scarring), or liver cancer later in life. The virus is transmitted through direct contact with infected blood and bodily fluids, and from an infected woman to her newborn at birth. Is there a safe vaccine for hepatitis B? YES! The good news is that there is a safe and effective vaccine for hepatitis B. The vaccine is a series, typically given as three shots over a six-month period that will provide a lifetime of protection. You cannot get hepatitis B from the vaccine – there is no human blood or live virus in the vaccine. The hepatitis B vaccine is the most widely used vaccine in the world, with over 1 billion doses given. The hepatitis B vaccine is the first "anti-cancer" vaccine because it can help prevent liver cancer! Who should be vaccinated against hepatitis B? The World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) recommend the hepatitis B vaccine for all newborns and children up to 18 years of age, and all high-risk adults. All infants should receive the first dose of the vaccine in the delivery room or in the first 24 hours of life, preferably within 12 hours. (CDC recommends the first dose within 12 hours vs. the WHO recommendation of 24 hours.) The HBV vaccine is recommended to anyone who is at high risk of infection. -

UNEP Mercury Treaty Protects Access to Thiomersal-Containing Vaccines
UNEP mercury treaty protects access to thiomersal-containing vaccines United Nations Environment Program has developed a treaty on mercury in an effort to protect human health and the environment by limiting mercury releases. In the course of the negotiations, a proposal was made to restrict vaccines that contain the preservative thiomersal under a section of the treaty that prohibits trade of mercury-added products. The implications of restricting thiomersal, an ethyl mercury-containing preservative, would be significant. According to SAGE, “Thiomersal-containing vaccines [are] safe, essential, and irreplaceable components of immunization programs, especially in developing countries, and…removal of these products would disproportionately jeopardize the health and lives of the most disadvantaged children worldwide.” The treaty annex that describes prohibited products specifically excludes “vaccines containing thiomersal as preservatives” under a short list of products the authors intended to emphasize were to be protected. Protecting access to vaccines came as the result of a strong partnership between WHO, UNICEF, GAVI, and civil society advocates and experts around the world to educate country delegates, who predominantly came from ministries of environment. This was also a wonderful partnership with animal health experts, who similarly rely on thiomersal for veterinary vaccines. By facilitating communication between ministries of health and ministries of environment, strong statements are made by delegates about the essential role of thiomersal-containing vaccines in protecting human health. PATH will be collecting and disseminating additional information about how the community came together around this issue and lessons learned in the coming months. . -
(DTP-Hep B-Hib) Vaccine Into the EPI Programme

SS /D.M.OO of Provincial /Base Hospitals, Heads of Decentralized Units and, Medical Officers of Health Introduction of combined pentavalent (DTP-Hep B- Hib) Vaccine into the EPI A decision has been taken to introduce Hib (Haemophilus Influenzae B) vaccine into the EPI programme in Sri Lanka from year 2008. This decision is based on the recommendation by the National Advisory Committee on Communicable Diseases. The Hib vaccine will be in the form of a combined pentavalent (DTP-HepB-Hib) vaccine, which would include DTP and Hep B and therefore would replace both DTP and Hepatitis B in the present schedule. Background The bacterium, Haemophilus influenzae type B (Hib), is an important cause of infections in infants and young children; severe disease in adults due to Hib is uncommon. Where it has been studied carefully, Hib is the leading cause of acute bacterial meningitis in infants and children less than five years old, accounting for one-third to one-half of all cases of bacterial meningitis in this age group. Bacterial meningitis is fatal unless treated immediately with antibiotics. Even with proper treatment 3-25% of affected children may die. Permanent disability with sequelae that include deafness, learning disabilities, and difficulties in movement is not uncommon among those who survive the infection. -
Pentavalent and Hexavalent Vaccines
Pentavalent and Hexavalent Vaccines Cold Chain Equipment Database ID 3_7 Year 2004 The freeze indicator is used to warn of freezing and is packed with vaccines that are sensitive to freezing temperatures: DTP, TT, DT, Td (freezing point of -6.5°C), hepatitis B (-0.5°C), liquid Hib and their combinations (DTP-HepB, and DTP-HepB+Hib vaccines) and JE. Every refrigerator storing vaccines should have a freeze indicator (Freeze Watch™). It is strongly recommended that one freeze indicator be placed in each cold box during vaccine transport and distribution. This is critical in places subject to low temperatures. Immunization in practice: a practical resource guide for Health workers – 2004 update_____Module 3: The cold chain WHO/IVB/04.06 Page 13 Vaccine Handling Database ID 81_1 Year 2006 The recommended conditions for storing vaccines used in immunization programmes are shown in Appendix 81_1. This diagram also indicates the maximum times and temperatures in each case. At the higher levels of the cold chain, i.e., at national (primary), and regional or province level, OPV must be kept frozen between - 15oC and -25oC. Freeze-dried vaccines (i.e., BCG, measles, MMR and yellow fever) may also be kept frozen at -15oC to -25oC if cold chain space permits, but this is neither essential nor recommended. At other levels of the cold chain (intermediate vaccine stores and health facilities), these vaccines should be stored between +2oC and +8oC. All other vaccines should be stored at between +2oC and +8oC at all levels of the cold chain. Liquid formulations of vaccines containing diphtheria, pertussis, tetanus, hepatitis B, Haemophilus influenzae type b, IPV and their combinations should not be frozen. -
