I totally agree with you that every chapter of the Spillover book we have read has been its own kind of interesting. Ebola being a zoonotic disease and its transmission, was also something that was new to me. It is incredible that they now have a certified vaccine against Ebola and I'm glad you updated everyone through the forum. It is surprising though that the vaccine has an age restriction. Humans invading the ecosystem has thrown it off-balance, and as a result, it is being balanced through natural mechanisms. So, it is understandable to be careful around what other microbes animals carry, especially primates.
