LONDON, Dec 12 (Reuters) - More children worldwide are now immunized against killer diseases but the task has become harder due to conflicts, epidemics, urbanisation and migration, the head of a global vaccine group said.
Seth Berkley, chief executive of the GAVI vaccines alliance, said his agency was now focusing on how to get vaccines to people in rural areas, those isolated by war and refugees.
