The Coronavirus may be caused by a US biological attack that targeted China first and then Iran.
There are great scientists who confirmed this concept (biological attack), including the Russian biological scientist Igor (Nikulin) who emphasised that this is not a normal virus and was formulated in laboratories.
The US has 25 dangerous laboratories surrounding China, Russia and Iran.
Even in American films, we see that the American administration carries about experiments and testing on Americans themselves.
It’s quite possible that Europe and America will gradually reveal the fact that they already possess a vaccine (for the Coronavirus), but are just waiting for the price to be raised in order to make more money by using it later on commercially.
