Mission
THE ROSTROPOVICH-VISHNEVSKAYA FOUNDATION (RVF) IS A GLOBAL DEVELOPMENT ORGANIZATION THAT PROMOTES THE HEALTH AND WELLBEING OF CHILDREN IN NEED THROUGH PARTNERSHIPS THAT CREATE SUSTAINABLE, TRANSFORMATIONAL PUBLIC HEALTH PROGRAMS AROUND THE WORLD. RVF IS A NON-POLITICAL, NON-PARTISAN CHARITABLE ORGANIZATION.
Program accomplishments
- RVF'S MAJOR INITIATIVE TO PROVIDE SAFE WATER FOR DRINKING AND PERSONAL HYGIENE TO CHILDREN AND THEIR FAMILIES IN GAZA WAS RESUMED IN APRIL 2024. IN 2025 RVF OPENED 9 POTABLE WATER DISTRIBUTION SITES THROUGHOUT GAZA. OF THE 18 POTABLE WATER SITES OPENED BY RVF SINCE APRIL 2024, 11 SITES REMAINED FULLY OPERATIONAL BY THE END OF 2025, DESPITE HORRIFIC WARTIME CONDITIONS. THESE SITES SERVE APPROXIMATELY 200,000 CHILDREN AND THEIR FAMILIES WITH FREE POTABLE WATER. EACH SITE IS EQUIPPED WITH A WATER DESALINATION UNIT USING REVERSE OSMOSIS AND POWERED EITHER BY A DIESEL-RUN GENERATOR OR A SOLAR POWER SYSTEM. THIS INITIATIVE IS MADE POSSIBLE BY A GENEROUS GRANT FROM THE UAE. ACCESS TO SAFE DRINKING WATER IS A GLOBAL PUBLIC HEALTH PRIORITY. IN THE GAZA STRIP, HOME TO OVER 2 MILLION PEOPLE, THERE IS AN URGENT NEED FOR POTABLE WATER TO HELP CHILDREN AND THEIR FAMILIES SURVIVE. RVF IS CONTINUING THIS LIFE-SAVING WORK IN 2026 AND INTENDS TO SCALE IT UP DRAMATICALLY. GIVEN THE SCOPE OF THE DESTRUCTION IN GAZA, COMMUNITY-BASED FIXED WATER DESALINATION SYSTEMS THROUGHOUT THE TERRITORY ARE THE MOST EFFECTIVE WAY TO PROVIDE POTABLE WATER TO THE POPULATION, AS IT WILL BE YEARS BEFORE PERMANENT INFRASTRUCTURE CAN BE REBUILT. RVF IS IN REGULAR CONTACT WITH THE GOVERNMENT OF THE UAE AND OTHER DONORS TO CONTINUE AND EXPAND THIS LIFE-SAVING WORK.Expenses $2,200,658
- RVF WORKS IN PARTNERSHIP WITH LOCAL GOVERNMENTS TO INTRODUCE MODERN VACCINES FOR CHILDREN INTO THE NATIONAL ROUTINE VACCINATION SCHEDULES IN MIDDLE INCOME COUNTRIES (MICS) AND PUBLISHES THE EPIDEMIOLOGICAL RESULTS OF THE PROGRAMS IN PEER-REVIEWED SCIENTIFIC JOURNALS. THE VACCINATION PROGRAMS ARE IMPLEMENTED ENTIRELY BY LOCAL HEALTH CARE WORKERS, THEREBY BUILDING LOCAL CAPACITY AND OWNERSHIP FROM THE BEGINNING, AND ARE FULLY SUSTAINED BY THE HOST GOVERNMENTS WITHIN 3 YEARS OF INCEPTION. FOLLOWING THE LAUNCH OF THE RVF-INITIATED ROTAVIRUS VACCINATION PROGRAM FOR ALL INFANTS IN GAZA AND THE WEST BANK IN 2016- APPROXIMATELY 135,000 BABIES ANNUALLY RVF, WITH FINANCING FROM THE BILL & MELINDA GATES FOUNDATION, HAS BEEN CONDUCTING SURVEILLANCE DOCUMENTING THE IMPACT OF THE ROTAVIRUS VACCINE ON THE DISEASE BURDEN. THE RESULTS OF THE FIRST PHASE OF THE SURVEILLANCE WERE PUBLISHED IN THE PEER-REVIEWED JOURNAL VACCINE. UNFORTUNATELY, DUE TO THE WAR, THE SUPPLY OF ROTAVIRUS VACCINE WAS INTERRUPTED FROM JUNE THROUGH DECEMBER 2024, SO THERE IS A POSSIBILITY THAT ROTAVIRUS DISEASE WILL REEMEERGE BEFORE THE VACCINE SUPPLY CAN BE REPLENISHED AND VACCINATION RESUME IN 2025. IN EGYPT RVF CONTIUNES ITS INITIATIVE TO INTRODUCE THE ROTAVIRUS VACCINE INTO THE NATIONAL IMMUNIZATION SCHEDULE FOR CHILDREN AND TO TRANSFER THE TECHNOLOGY TO MANUFACTURE THE VACCINE IN THE COUNTRY. THE RVF-SPONSORED BASELINE STUDY OF ROTAVIRUS DISEASE PREVALENCE IN EGYPT, FINANCED BY THE GATES FOUNDATION AND PUBLISHED IN THE EGYPTIAN PHARMACEUTICAL JOURNAL, HAS LENT MOMENTUM TO THE REGISTRATION PROCESS OF THE VACCINE IN EGYPT AND THE PLANNING OF THE TECH TRANSFER FROM THE INDIAN MANUFACTURER TO AN EGYPTIAN VACCINE MANUFACTURER.Expenses $120,831 · grants $67,956 · revenue $81,900
