Vaccination for SARS CoV-2

As I had been a researcher in Biochemical field over 30 years ago, I can see better a little bit than ordinary people in relation with SARS CoV-2. Especially, the difficulty and uncertainty in Polymerase Chain Reaction test, how difficult it would be to step the fixed procedures exactly. Catching the aimed Genom by the oral mucosa without any obstacles such as contamination is far above dream. Toy-like kit for the purpose handled by almost a laymen would have any reliability? Before that, PCR test it self is not an actually reliable attitude, the very researcher who invented the method went away leaving an important warning, "PCR must not be utilized as identification of Genom!". Probably an awful Murder! Also it is not clear who will take the responsibility for various foreseen problem, fatal result because of Immunodeficiency, birth of malformed child and residual liposomes and Lipid nanoparticles consistently remain in Liver, Spleen, Ovary and Adrenal grand. Who can say that Miserable results would not be waiting in future? Remember here, bacteria and virus are completely different pathogen each other, so not the specialist in ordinary bacterial infectious disease but that of virology should be in the front of the Govern Expert Meeting. Another specialist in virology says that Herd Immunity in our country has been acquired among us already, so no vaccination to Mass people is required at all.
