Luanda - Over 6.0 million children will continue at risk of infection by poliomyelitis virus if the levels of vaccination and sanitation are not improved, says a press note.

According to the document, to guarantee the success of the vaccination campaign, the Angolan government calls for the families, communities, municipal and communal administrations to renew their commitment to eradicating this illness, supporting the vaccination campaign for children under age of five.
