Additionally, if you are asked to sign a permission slip before the shot, ask the health provider for the vaccine lot# too. Write it down on the permission slip and ask the health provider for a copy of the permission slip with the vaccine lot# on it. If you are injured by any jab that you take, please report it to the Vaccine Adverse Event Reporting System - hhs.vaers.gov . "Batch-code" = "Lot Number" = the number they write on your vaccination card should be the same number you wrote on your permissions slip.

(If that is even possible.)
