Your visions will happen
Yes you are correct. There is a lot of money in a vaccine right nowI'm 99% sure there will be a vaccine, but there's always the chance. While there are no vaccines for the other variants of coronaviruses that affect humans, that is mainly due to economic incentives. The coronaviruses in circulation other than covid 19 cause just a common cold, so there's no incentive to produce a vaccine. The other severe coronaviruses (producing MERS and SARS) fizzled out pretty quickly too. The virus itself seems pretty stable (doesn't mutate super fast) and people develop antibodies, so scientists should be able to crack the code.
About the part about being secure financially, I totally agree.
Kyrgios never wanted to play tennis even before Corona so we should hardly take his opinion as gospel haha
