Blindly getting every vaccine available can be foolish. It is good you are putting thoughtful consideration into this. Vaccinations can damage the natural immune system and stunt it from developing fully.
For my husband and I, we agreed to do vaccines that were time tested...such as DTaP and polio (dead). We refused Hep B (my infant was not sexually active and I was negative so he had no need for such a vaccine that would only protect him for 10 years or so anyway) and the rotovirus (that one was actually pulled off the market about 10 years ago because it was killing kids...and only recently brought back into the vaccination schedules!) We will also be skipping chicken pox since that is not a fatal disease and is simply an inconvenience (and by allowing your child to get chicken pox, you are protecting them from getting shingles as an adult which the vaccine does not help with!) We also won't be getting the Hep A vaccine as we do not feel my son is at risk for that either.
The MMR is obviously the one that most people feel is the riskiest. I can tell you two things for certain for us, there is NO WAY I will do the 3-in-1 vaccine. Period. It's not worth the risk to me. IF we vaccinate it will be is 3 separate vaccines, spaced a month apart. Additionally, we will not consider even the separate vaccines until my son is closer to school age. There is NO HARM in waiting!
Additionally, you do not have to have vaccines to attend school in FL. You do have to go to your county health department, watch a brief video about vaccines and then sign a document.
The doctors want to vaccinate on their schedule, but you, as the parent, can alter that schedule to best fit your child. Refuse more than 1-2 vaccines per appointment! Refuse vaccines that are not necessary or contain live viruses if you don't feel comfortable with them. Be your child's advocate and minimize the amount of toxins you inject into your son at one time, or at all. You don't have to be completely against vaccines or totally for them in order to exist in our society....but you should be very thoughtful about them.
You likely wouldn't lose too much sleep if you skipped a chicken pox vaccine and your son caught chicken pox. Would you forgive yourself if he had a bad reaction to the MMR vaccine though?
The bottom line is, can you live with your decision if it turns out badly afterwards?
