What other travel vaccines are recommended (other than Yellow Fever)?

There is no "legal" requirement for any vaccine other than Yellow Fever (for most countries). However you MUST confirm the same by checking the CDC website here or by contacting the local embassy of the specific country.
As far as our Charak Clinics is concerned, we are recommending the following Optional vaccines for Personal Protection to travelers to African and South American countries

• Typhoid Vaccine (repeat every 3 years)
• Hepatitis A (2 doses at 6 months interval for life-long protection)
• Cholera Vaccine (new drops available - 2 doses at a gap of 15 days)

These would help prevent common serious water-borne diseases prevalent in these regions.
