Many trials of hydroxychloroquine are designed to fail because they deliberately omit zinc. HCQ requires high levels of zinc in the body to work well. Only some people have sufficient natural body levels of zinc for HCQ to block virus replication. Most people must take zinc pills along with HCQ for the therapy to work.
Evil dems would rather see people die than something President Trump recommends succeed.
Zinc with hydroxychloroquine causes a two-fold hit on the virus. HCQ prevents the virus from entering the cell where it hijacks the reproductive machinery. It also provides pathways into the cell for zinc. At high levels in the cell, zinc destroys the RNA dependent RNA polymeras, which stops the replication process.
