Because of the production of aneurysms, we'll add to this Kawasaki link, recalling that The Netherlands is a major vaccine-producing country.
'The Post-SARS Era. During 2000-3 winter season, a new HCoV, strain NL63, was isolated in The Netherlands. Initially isolated from a young child with lower respiratory tract disease, NL63 represents a group of newly described group 1 coronaviruses which are associated with both upper and lower respiratory disease in young children.....Shortly after publication of the discovery of HCoV-NL63 at the Amsterdam Medical Center, a report from the Rotterdam Erasmus Medical Center described a newly identified HCoV (named HCoV-NL) from a clinical sample obtained in 1988.
Furthermore, less than a year later, the discovery of the New Haven coronavirus (HCoV-NH) in the United States was described at Yale University. An association was suggested between HCoV-NH and Kawasaki disease, a systemic inflammatory disease of unknown etiology, but this possible association is controversial, as two reports have failed to show any link between this disease and HCoV-NH. As mentioned above, HCoV-NL63, -NL, and -NH probably represent three strains of the same viral species.'

Noting that it was in 1988 that USAMRIID's military began experimenting with chloroquine and bungarotoxin from the Chinese krait, Bungarus multicinctus. Chloroquine was shown to increase snake venom potency 17-fold.
