Trump is saying that Biden's isn't up to the challenge of Covid-19..

The goal of OWS was to "produce and deliver 300 million doses of safe and effective vaccines, with the initial doses available by January 2021. The Democrats said they wouldn't get the vaccine, mainly because of Trumps involvement… Then "they" came out with their own vaccine.

Is it true the military was working on a vaccine before covid broke?

When did we start seeing problems with vaccines?
