I have read what everyone says about vaccines, that it is my health and I am responsible. I didn't see mention of required vaccines, or if anyone had opted for the suggested vaccines. I spoke with my doctor who referred me to the CDC website. Not helpful, other than to make me rethink taking this tour! It still remains unclear to me what the travelers to this area do as mandatory and as voluntary. I'd appreciate hearing what experienced Tauck passengers have done. Thank you ~
