I was trying to upload this a file but it was too large so I've copied the link to it. It is scientific study from 2005 on the success of Chloroquine in treating Sars coronavirus infections. It shows that the information on chloroquine was readily available and known about in treating sars infections as far back as 2005, 16 years ago, so why was it not used this time around and why are they insisting on vaccination?
