The only live vaccine a 6 MO would have gotten would have been the Rotovirus one. Be careful at diaper changes and be fastidious about hand washing. Rota is spread through fecal matter.<br><br>
The live vaccines come at 12 months.<br><br>
The only other thing to consider is that after vaccination, the 6 mo might be more susceptible to other infections because of the assault on their immune system and could pass anything it picks up to your child - a cold etc.
FWIW, I am pretty sure my two unvaxxed boys are the only ones in their entire daycare. HTH <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up">
