This actually sucks because my dad man. I couldn't convince him not to get the shots. Lucky for me he had no adverse reactions, praying he got saline. Is that crazy to ask since we live in the suburbs? Maybe if a community has money they give the shots that won't make you sick if indeed they are different batches. Anyway he is 64 and based on the past I feel as if he will want to get it. Its weird with him. I think he falls into a category where he has just given up.its sad.
