Again, we do not know the giraffes have been vaccinated. We know that the zoo has doses and have given them to OTHER animals. You are assuming the vax was given to the giraffes.

A lot of these articles are mentioning causes of deaths as different diseases. Before the vaccine, animals dying from diseases is not new. That happens constantly. You'll find articles of animal deaths every single year. None of the articles in the link you provided links an animal death to the vaccine.
