My concern is that this issue of "leaky virus" might just be intentional in order to increase public necessity of future vaccines.
Another thought that I have is that the use of a zapper right after vaccination might provide significant benefit by possibly killing any virus that might leak. Sadly, it is highly unlikely that the medical community would even consider testing this. If they showed even the slightest efficacy of zapper usage, or even of things such as Colloidal Silver , it could spell doom to their profits.
