Thank you for your query on Healthcare Magic,
As you are going to Africa and you have to campaign outside a lot there is risk for animal bite especially dog bite.
In this situation I advise you to take anti rabies vaccination
prior to going Africa as a pre-exposure prophylaxis
As rabies vaccine
is safe and preformed antibodies
against rabies due to pre-exposure prophylaxis always more protective than post exposure prophylaxis and more appropriate in risky professions and regions.
Hope I have answered your query.
