A man who works in the medical profession defends the indefensible, so how is it possible that in less than 1 year a vaccine can be invented, tested, produced and declared safe if any other drug requires at least 5 years of clinical research?
Firstly, near enough every vaccine scientist in the world was working on the same problem. Secondly, vaccine trials involve giving some people the vaccine, giving a control group a placebo, and then waiting. It is not ethical to deliberately expose people to a disease, so we have to wait. In the case of most diseases, it takes years to be sure there has been enough exposure to the disease in both groups to reveal a difference. In the case of global pandemic, the same exposure can be reached in months or even weeks.
That's the problem of you and others like you, you don't accept anything that doesn't work in your favor, regardless of who it is and how good the research is.
I don't accept opinions. Show me some evidence. I've asked anti-vaxxers on this board countless times for a single shred of evidence; they always respond with nothing.
