There is a new drug called Remdesivir still in the testing phase just been approved in Australia for use, although not a cure but showing signs of increasing recovery times in severe cases of COVID-19. I have only found info on a trial currently undertaken by a German company called CureVac that is testing a possible vaccine, their trial will last up to 15 months which started early June which looks promising but won’t be available until late 2121 if successful.
Return to normality Internationally solely relies on a Vaccine as country’s have worked hard to slow it down. I couldn’t see any country allowing US or Chinese tourist in otherwise.
