Thanks for Healthcaremagic,
Your question regarding vaccination
when you are visiting Tanzania which is endemic for yellow fever and tropical region so Typhoid is always risk.
You should take vaccination 10 days before travel and these vaccine can be taken simultaneously. Yellow fever vaccine
should be used care fully in immune compromised individual and egg allergy
should report to your medical person.
In case of malaria they would give you chemo prophylaxis.Demyelinating disease
there is small risk but can be given.
Hope this helps.
