RE:I cannot understand You don't have a PHD in viral epidemiology, nor decades of research into the 5Ws of preparing and producing vaccines!
The production of these things takes time... a lot of time, because we don't allow Cletus to produce a vaccine from his basement on the basis of giving it to 6 people. Clinical trial runs needs 100s of thousands of trial participants where the research is peer reviewed!
That's because, we don't want the 'vaccine' to kill people before Covid does!
