Wait just one minute thar partner! Here's a few things I researched recently. First there were 40 vaccine candidates. Now there are 37 worldwide.
A promising Australian candidate for a coronavirus vaccine has been abandoned after trial participants returned false HIV positive results. - Source BBC - apparently it gave the volunteers positive HIV test results. So they tossed it. Australia is now working on getting the Astra Zeneca vaccine.
Merck's vaccine was sort of ok - BUT it didn't give as much protection as hoped for, so they tossed the whole project - that accounted for the other two tossed.
Also, it's technically not a "vaccine" - it is a biochemical agent. A true vaccine used a dead or weakened virus or bacteria to give the receiver immunity. This one using new technology, not yet fully proven (it's still in the "experimental" stage), that changes DNA. Lovely.
Then if you want to get paranoid - I saw this last night on a show I don't normally watch and was FLOORED by the insinuation. If you don't do anything else this week, watch this short video. Then look up the NIH (National Institute of Health) documents and follow the money! Follow the money!

The coincidences are too much. Way too much.
