(Please Respond to her post)Hi Shaunglazier,I enjoyed reading your post. I like the idea of the vaccine for Bilharzia but I read that is not common in the United States. However, it does affect almost 240 million people worldwide. It is more common in in tropical places and in Africa. I do think that a vaccine would be great but can you think of any other ways that it can be prevented? Especially for people who travel out of the US to other countries or islands, that may not experience any complications with that specific parasite. Should government officials have services that test natural waters around the areas where the parasite is common?
