I have always gone on schedule for all my kids. I have not seen any adverse effects. I've never heard of an alternative schedule, but I've never looked into Dr. Sears either so I just looked it up and just on the first paragraph I see something off. He says to wait 2 months to give your child the first dose of Hep B vaccine because it is an STD. It is not an STD, it is passed by infected blood and bodily fluids with blood in them. I haven't looked too much into it, but I just feel that if a majority of Doctors feel these vaccines are safe and necessary, and most have been given for many years to children, why question it? You can research all day on both sides if you want, but still, majority rules. What I'm not getting is the H1N1 vaccines for my children because it is a new vaccine, even if they are saying it's the same. Overall, I think I would much rather an alive child, then one that has gotten one of the awful diseases that we've managed to ultimately obliterate in US society. That's my 2 cents, just another mom with another opinion!
