But the question of the OP should be - when will the vaccine be released to public? Because Covid will be here in the community for years, it will not be totally contained for few months or years. Vaccine or effective treatment is our answer to have peace of mind mingling again with other people. But medical industry should make it economical and not just another source of profits for them. There are some cheap medicines that can treat the infected and those should be the one that they need to develop, not another expensive medicine for their own profits.
the medical community has already shown good decentralised processes of finding a vaccine. many institutions are working on it. take for instance the cambridge trials. they are actually willing to do the work and release the info. they are not going to patent it and charge £xxxx a dose. they are going to let al countries have it and those countries make their own. (just gotta see if cambridge trials pass the tests)
this wont be a case of only the super rich can afford it. everyone will have the oppertunity to have it. including the homeless
