There is nothing inherently dangerous about this vaccine over other vaccines. Some adults and children may have severe reaction to vaccine components or the manner in which a particular vaccine is manufactured. All childhood vaccines have a risk. A parent should understand that before allowing your child to be vaccinated for a whole host of childhood diseases. On a percentage basis there are always going to be adverse effects and some deaths from anaphylaxis. If you, as a parent don’t understand that, I suggest you retake Bio 101!
As I have repeatedly stated my major problem is making it mandatory for 9 year olds........
