On December 14, 2017, a faculty member of a university in Hunan Province reported that an anthrax vaccine strain might have recovered virulence during an undergraduate experiment and potential exposure could not be ruled out for the students involved. Upon receiving the case report, the CDC, health bureaus, and local governments at the county, prefectural, and provincial levels promptly organized experts in different fields (including epidemiologists, biosafety experts, and laboratory testing experts) for case investigation, evaluation, and response. As the investigation results showed, no virulence recovery was identified in the involved anthrax vaccine strain;and no contamination of Bacillus anthracis was detected at the involved areas. Thus, the university returned to normal functioning.

The title compound 2-（2-methoxy-4-nitrophenylcarbamoyl）phenyl-4＇-fluorobenzoate （C21H15FN206, Mr = 410.35）, a fluorine-containing derivative of salicylamide, was conve- niently synthesized through two steps and crystallized in the orthorhombic space group P21/c with a = 7.6453（15）, b = 14.323（3）, c = 17.035（3） A, V= 1865.4（6） A3, Z = 4, Dc = 1.461 Mg/m^3, 2 = 0.71073 A, μ（MoKa） = 0.115 mm-1, F（000） = 848, R = 0.0705 and wR = 0.1834 for 3267 independent refections with 1 〉 2σ（I）. X-ray analysis reveals that the dihedral angles formed between the 2-methoxy-4-nitrobenzene and benzene ring, the benzene and 4-fluorobenzene, and the 2-methoxy-4-nitrobenzene and 4-fluorobenzene ring are 3.2（4）, 69.8（3） and 72.9（2）~, respectively. Bioassay shows that the title compound has anti-parasitic activity against hydatid protoscoleces.
