Assessment on Quality of single polio vaccine type 1 produced on primary monkey cells

ABSTRACT

Background: \r\n', u'October 2000, Vietnam was acknowledged as the country to successfully eradicate the polio by WHO.This success was partly due to the oral polio vaccine (OPV) produced on the primary money cells by the Centre of Research, Production of vaccines and biologicals, Ha Noi. In 2006, the Centre developed the single polio vaccine type 1 from primary monkey cells.\r\n', u'Objectives: \r\n', u'To evaluate the safety and antibody titre .\r\n', u'Subjects and method: \r\n', u'6 lots of single polio vaccine type 1 (ISO- 90, Antibodies of Polio type 1,2,3; the standard sample F113 from Japanese research on Polio Institute\ufffd?\r\n', u'Using the tests (T- maker, D maker, PFU, CCID50) to check the safety of single polio vaccine type 1. \r\n', u'Results:\r\n', u'After 14 days, 6/6 lots of viruses were observed via the microscope that they stayed in well developed, and of no serious adverse affects.There was no appearance of degenerated cells. \r\n', u'Conclusion:\r\n', u'6/6 lots of single polio vaccine type 1 produced on Macca mulltta monkey kidney cells with the first time passage at POLYVAC in 2006 are safe and high antibody titre.\r\n', u'
