Many countries are in line to produce the coronavirus or Covid-19 vaccine in the world which is facing an enormous medical epidemic. What is to be maintained that mederna, remdesivir, HCQ,  dexamethasone are just possible vaccines and not the ultimate vaccine. 

Countries like Russia, Israel, USA, China, India and others are trying their best effort corona vaccine making operations to make the vaccine for this deadly disease. Whether or not they will be successful is another question but in reality only WHO (WORLD HEALTH ORGANIZATION) will notify and declare the covid-19 vaccine as the only solution, As far current updates are concerned we might see Russia as the first nation to develop Covid-19 vaccine otherwise it can be Israel and India who might be the first nation to produce corona vaccine for the world.

Till then it is only advised not to try out any medicine or injection just because a news report says it is corona vaccine. By next year or so we might get a corona vaccine throughout the world.
