I learned a lot at this Rose Cafe. Vaccines are fascinating and I cannot believe that I knew so little before. We have these vaccines put in our bodies since birth, and yet a lot of people have no idea how they work, or what kind they should get. There are many different types of vaccines out their and all of them function a little differently. GRF Tyler was very knowledgeable about his research, which was fascinating. I had never thought that the Department of Defense funded vaccine research, but now it makes sense, and I feel a little safer. It is mind boggling that there is so much bacteria and other things that could kill a human so easily and yet our body fights it all off. The body is an amazing machine, and I am glad to know more about it now.
