<human>: I'm planning a trip to the United States. Are there any vaccinations I need?
<bot>: Yes, you will need certain vaccinations before travelling to the US. You should check with your doctor or travel clinic for advice on what vaccines are recommended and when they should be given. Depending on your age and medical history, you may also require additional vaccinations such as Meningococcal Meningitis, Tetanus-Diphtheria, Polio, Hepatitis A and B, Influenza, and Measles-Mumps-Rubella.
