On Monday, I received a booster shot so that I can welcome an anticipated grandchild into the world.
The T-dap concoction is to guard me from transferring whooping cough, especially, to the newborn, as well as diphtheria and tetanus.
As a healthy adult I probably dont have any transferable diseases that could prove life-threatening to an infant, but in the off chance I might, getting the vaccination is the least I can do.
