I don't think people were downvoting because the government didn't provide support for the development of this vaccine, but because OP was quoting an extremely unreliable source on this topic.

Also a source that's trying to claim personal responsibility for the successes of others, where none is deserved. A government that had the capacity to develop treatments but choose not to would have been in dereliction of their duty; if there's ever been a clear, classic case for communal response, this is it. Claiming as success a response that only partially obstructed dealing with the virus is obscene; and even the parts that appear to be well-executed were clearly not due to exceptional executive action; many parts of government were involved, not least of which the bureaucrats (aka the deep state, those horrible people that actually keep things running).

Exceptional leadership would have been taking action December 2019 or early January - and as many south-east Asian countries show: even clear guidance and simple public health measure matter hugely; but people need to understand and support the measures, because it all hinges on real people changing their behavior; and creating controversy and abusing possible future treatments as distractions from actions that needed to be taken many months ago - and still do - undermines that.

And to cap it all off, the president is not working towards delivering those treatments and vaccines, because he's actively undermining the normal transition of power. Even if the election outcome were uncertain, gambling with people's lives like that shows a careless disregard for actually serving country - because an ethical person would at least work to protect others when it's not only their job, but easy, and conventional to do so.
