Coronavirus vaccine

Now the only possibility to come back to the normality is with a vaccine for coronavirus. The last news we have is that an english laboratory have developed a really successful vaccine that has already been tested in humans with good results, they say it will be launched  into the market in September of this year with an initial quantity of 400 million doses. These are very enlightening news, because we already have a more clear horizon in relation to the pandemic, and when the world is going to begin to recover from the heavy economic consequences of it, but there is still a long way ahead.
