More than $4.3 billion was pledged by major public and private donors at a conference in London on Monday to aid projects vaccinating children in developing countries. The conference — co-hosted by the British Government and the Global Alliance for Vaccines and Immunization (GAVI) — had hoped to raise $3.7 billion.
Donors included corporations, philanthropists like Microsoft co-founder Bill Gates and governments donating to GAVI for the first time, including Japan and Brazil.
