Pandemics Don't Mean Profits?

Vaccines are our major protections against viral infections, like the current COVID-19 outbreak, that seems to be spreading in many parts of the globe and may become a pandemic. A rather pessimistic account, however, suggests that the time line and economics of vaccine development (generally taking years and costing a lot) does not fit with the time line of a pandemic (often spreading and killing quickly before disappearing within months). This acts as a disincentive to Big Pharma, where there is a preference to invest in drug treatments that will sell for extended periods generating profits (https://www.theguardian.com/commentisfree/2020/mar/04/market-coronavirus-vaccine-us-health-virus-pharmaceutical-business). It is notable that no vaccines were actually generated for most other recent coronavirus infections of humans including Sars Cov-1, Mers or Zika. The only one with some success is development of a vaccine for Ebola. As the technologies do exist to develop protections against viral infections and we could learn more with each outbreak (if we didn't simply abandon information), we should explore methods of being less reliant on profit-making companies with their tendency to patent anything that generates cash?
