Which statement is true regarding the Adacel/whooping cough vaccine?

The Adacel vaccine, which is used to protect against whooping cough (along with tetanus and diphtheria), is typically not administered directly in-house by healthcare facilities but rather through authorized providers or pharmacies. This means that patients may need to visit a designated location to receive the vaccine, reinforcing the understanding that the vaccine is commonly provided externally rather than within the primary healthcare setting. This aligns with the common practices surrounding vaccinations, where specific vaccines are managed through larger distribution networks or specialized clinics rather than being offered as a standard in-house service.
