I have no idea what is going w/ that. It was supposed to be a slow growing virus, maybe there were problems w/ that. Perhaps its just showing low immune response to the virus (as was seen earlier, and kids got upped to 2 rounds) and may require some reformulation of the injectible (say for a higher titer count.)
They are saying tho that kids who recieved that vaccine won't need additional shots, nor was it done for safety reasons. Important point.
There is continous monitoring and testing that is going on w/ the vaccine, so they probably saw something that wasn't going as well as hoped. So far it was only Sanofi, and not any of the other 3 manu's. We shall see.
