Vaccinations for traveling teen

[Guest guest]

My 17-yo-son is going to the Dominican Republic this July with church youth

group. They are recommending highly (but not requiring) many vaccinations prior

to trip.

I am worried about this. We are currently chelating and my son has high levels

of aluminum. So far, his mercury levels are not that elevated, but we haven't

been chelating all that long.

The group leader said he would at least like for my son to get the Malaria

vaccination.

Any thoughts or advice on this would be much appreciated.
