what happens is when the needle is being injected into me and I shake or move just a little is that bad and do I have to get the vaccine again or is there going to be a reaction what should I do.
I imagine the only really worrisome side effect would be that it would hurt more during and after the injection. The only way I can see that you'd need another shot is if you moved so violently so as to not be injected with the vaccine.
