During testing on many of these dead virus’ and even the live virus, they will look at how much antibodies are produced. If during lab tests they get a certain number of antibodies then they consider the vaccine a success. What they do not look at, is the effectiveness of the vaccine fighting the virus. With a dead virus the antibodies don’t have anything to fight because the virus is dead, but it will produce antibodies which will do nothing because there is nothing to fight. This is how they say these vaccines are safe and effective. They are effective at making antibodies, the trick is they are not effective at attacking antibodies. Listen closely at the news when they have “experts” on talking about it, and they will always state carefully the vaccine is effective but never explain it in detail about the antibody creation vs the antibody fighting the virus.
