Global Alliance for Vaccines and Immunization (GAVI, the Vaccine Alliance) is an international organization built through public-private partnership. GAVI has supported more than 200 vaccine introductions in the last 5 years by financing major proportion of costs of vaccine to 73 low-income countries using a co-financing model. GAVI has worked in close co-ordination with Global Polio Eradicatio...

Genetic Algorithm (GA) is known as method to solve Traveling Salesman Problem (TSP). However, GA needs amount of time for finding approximate solution. Thus, this study proposes Genetic Algorithm with Virus Infection (GAVI). GAVI algorithm is using Virus Theory of Evolution (VTE) to be based on Genetic Algorithm (GA). GA can evolve by natural selection, while VTE can evolve by virus infection. ...

This paper reviews the experience of the Global Alliance for Vaccines and Immunization (GAVI) in introducing hepatitis B and Haemophilus influenzae type b vaccines in the poorest countries, and explores how financing for immunization has changed since GAVI Fund resources were made available during its first wave of support between 2000 and 2006. The analysis of Financial Sustainability Plans in...

STUDY QUESTION Can the equilibration steps prior to embryo vitrification be automated? SUMMARY ANSWER We have developed the 'Gavi' system which automatically performs equilibration steps before closed system vitrification on up to four embryos at a time and gives in vitro outcomes equivalent to the manual Cryotop method. WHAT IS KNOWN ALREADY Embryo cryopreservation is an essential componen...

Haemophilus influenzae type b (Hib) can cause severe invasive diseases which are, however, preventable by vaccination. To increase access to Hib vaccine, GAVI - the Vaccine Alliance - has provided financial support for 73 lower income countries worldwide. At the same time, GAVI has been implementing its co-financing policy, requiring recipient countries to pay a portion of vaccine costs and to ...

BACKGROUND Since 2005, Gavi has provided health system strengthening (HSS) grants to address bottlenecks affecting immunization services. This study is the first to evaluate the Gavi HSS implementation process in either Cameroon or Chad, two countries with significant health system challenges and poor achievement on the child and maternal health Millennium Development Goals. METHODS We triang...

BACKGROUND GAVI's focus on reducing inequities in access to vaccines, immunization, and GAVI funds, - both between and within countries - has changed over time. This paper charts that evolution. METHODS A systematic qualitative review was conducted by searching PubMed, Google Scholar and direct review of available GAVI Board papers, policies, and program guidelines. Documents were included if...

BACKGROUND In 2000, reuse of disposable syringes and inadequately sterilized syringes resulted in 39% of all injections being unsafe, causing 22 million infections. We describe the contribution of measles supplemental immunization activities (SIAs) and Global Alliance for Vaccines and Immunisation (GAVI) funding in replacing disposable and sterilizable syringes with auto-disable (AD) syringes t...

Child mortality has decreased substantially globally-from 12.6 million in 1990 to 6.3 million in 2013-due, in large part to of governments' and organisations' work, to prevent pneumonia, diarrhoea and malaria, the main causes of death in the postneonatal period. In 2012, the World Health Assembly adopted the Decade of Vaccines Global Vaccine Action Plan 2011-2020 as the current framework aimed ...
