Are any vaccines necessary for a 4-month-old baby and us if we are going to Mexico on an all-inclusive package?

Yes, certain vaccines are recommended for travel to Mexico with a 4-month-old baby. The Hepatitis A vaccine is strongly suggested, and should be received at least 1 month before your trip. The Hepatitis B vaccine is not mandatory but can be combined with the Hepatitis A vaccine for added protection. Additionally, a vaccine for traveler's diarrhea (Dukoral) and a preventive medication for malaria (such as Malarone) are also recommended. It is important to consult a healthcare professional for personalized advice and to schedule vaccinations and medications in advance of your trip.
