It didn't help that some scientists were pushing some sort of agenda. There's a Greek scientist called Ioannidis who works for Stanford, he had published work claiming that the disease wasn't as serious as what it actually is. Since this work was published some of his colleagues have said that he had fudged numbers and they asked not to have their names included in the list of authors.
The really weird thing about him is he was very well respected before this, he had a reputation as someone who had made valuable contributions to evidence-based medicine.
He did make some good points, to be fair - in terms of the need for testing, well-designed randomized and repeated samples; the need for open, fair clinical data so that the efficacy results are reproducible. All of those points are well taken.
But then he also had this contrarian anti-lockdown stance. Later it came out that the project was funded by Jet Blue (an airline company) and I think he was not forthcoming about the funding source. Media latched on to that.
