Summary
Foot- and- mouth disease vaccines have played an important role in the disease control programs in Taiwan since the outbreaks of this disease in 1997. To understand the changes in vaccine imports and inspection situations, data were collected and analyzed from 1998 to 2005. 
The number of importing companies decreased gradually from seven to three. The imported batches were also decreased from 30 per year during the early time to about 14 in the past two years. Virus strains used for vaccine production contained the O-Manisa, O-Campos, and O-Taiwan at the early time and only the O-Taiwan strain had been maintained since 2003. The imported doses were increased gradually to 17 million doses in 2002. A dramatic decrease or increase of imports was observed during 2003-2004 and in 2005. Doses in each batch were increased from 350,000 to 1,750,000 in 2005. The markets were mainly occupied by one company during the first four years and were equally shared by three companies from 2002 to 2005. A total of 194 batches of foot-and-mouth disease vaccines were inspected during 1998-2005, including 9 batches that failed to meet the efficacy test during 1998-2000. The totally satisfactory rate was 89.53 % during 1998 to 2000, and it was improved to 100 % during 2001 to 2005.
