You are right that no alternative solution has been found but I feel it's been possible to stop tons of diseases without vaccines. The front will come under more control.
The word here is not "stop", but prevent since as long as there is no vaccine, it will not stop. We can prevent the viruses from spreading jus by following the protocols being stated by WHO or the people who have knowledge when it comes to this type of viruses. Avoid sharing fake news every time and let's take care of ourselves as long as we can since the vaccine is still not done.
