We've decided to try to have more children and just realized our attempts were successful.

My oldest are 9, 11 and 12 and they got whatever the recommended childhood vaccinations are (mumps, measles, etc). I'm unaware of any issues the previous vaccinations may have caused, they have always been healthy.

After what has happened, I'm aware and concerned about all vaccinations. Is the general consensus here that all vaccinations are potentially dangerous? Can we safely avoid all vaccinations of any kind, including the common childhood vaccines?
