Corona viruses have caused two other recent epidemics severe acute respiratory syndrome (Sars) and Middle East respiratory syndrome (Mers). An essential precursor to regulatory approval is Clinical trials which usually take place in three phases. The first is involving a few dozen healthy volunteers, tests the vaccine. The second is involving several hundred people who are usually in a part of the world affected by the disease and the third does the same in several thousand people. COVID-19 is new and scientists understand to some extent about how it behaves and spreads. The cost of creating a vaccine to protect people against the new corona virus will run into billions of dollars and could take many months. Here are some of the reasons why. •            COVID-19 vaccine time to get into the market is likely to be at least 18 months. •            Potential treatments require ...

What does Corona Virus Mean? Coronavirus  derives from the Latin which means Crown, as it is in shape of a sphere but covered in spikes, which resembles a crown. It has emerged from the Wuhan in China. As it continues to spread around the world, scientists are striving to develop ways of fighting this previously unknown threat. Computer Modelling is being used to track and predict its transmission, while virologists are attempting to engineer a vaccine while others are seeking drug treatments that can help those who fall ill with the infection. Coronavirus belong to a large group of viruses that can infect both humans and animals and can occasionally jump the species barrier. But while the first cases likely occurred in people who had close contact with infected animals, it seems that most new cases from this 2019-nCoV are being passed human to human. Some of the most common and challenging diseases are caused by coronaviruses. One of th...
