More than 23,000 units of blood have been donated since the Red Spring festival was launched in 2008.

The information was released by the National Institute of Hematology and Blood Transfusion at a June 30 conference to review five years of the campaign in Hanoi.

The 2012 drive set a new record of 7,684 units of blood collected in one day.

Over the past five years, the event has become an important campaign for compassionate, kind-hearted people. A number of blood donation models have been developed, which has contributed significantly to the campaign in Vietnam.

Addressing the conference, Minister of Health Nguyen Thi Kim Tien said the campaign has upheld the tradition of social generousity in the community.

She said she hopes that the Institute will continue developing the campaign to bring it closer to every citizen.

On the occasion, Vice President Nguyen Thi Doan granted the Labour Hero title to Director of the National Institute of Hematology and Blood Transfusion Professor Nguyen Anh Tri in recognition of his contributions to the campaign.
