No it isn't. The China Virus is not the flu virus. The China virus might or might not require booster shots like almost almost every vaccine requires - including chicken pox, polio, yellow fever, etc. Once again, the flu is a more complicated virus than most and is not the same as the China Virus and should not be compared to it. They have some similar symptoms but so do most diseases. The viruses themselves are completely different.
