The Department of Medical Sciences (DMSC) plans to test a freeze-dried version of a live attenuated smallpox vaccine that has been stored in Thailand for more than four decades, to see if it can effectively combat monkeypox.
Supakit Sirilak, director-general of the DMSC, said on Friday the vaccine material has been kept under the supervision of the Government Pharmaceutical Organisation (GPO) since smallpox was eradicated in 1980.
