January 14, 2020: There has been an ongoing shortage of yellow fever vaccine in North America. At this time we have only enough to supply travellers who have already booked an appointment with us. Yellow fever exists only in parts of South America and Africa. If you are travelling to a yellow fever zone hopefully you can locate a clinic in town (or elsewhere) that still has doses to administer. If none is available, you can book with us. We can provide you with a waiver certificate if you choose to travel under these circumstances. This usually, though not always, satisfies entry requirements. We will discuss this with you.
We expect to receive information regarding a renewed supply over the next several weeks.
