just finishing up 12 days in my primary and about to rack to my secondary..primary has bottom spigot to transfer..question is:when draining to the secondary,there will be a vaccum pulled on the primary..should the air lock be in or out ??...afraid of any contamination that might get sucked in...

Don't worry about the airlock's water contaminating the beer. Sure its good practice to remove the airlock but its best not to worry too much. Its all good.
 
That is the reason I use vodka in my air locks.

No germs get sucked in, just alcoholic goodness.
 
Take the airlock out. There will be a blanket of CO2 on the beer and any air pulled in will be lighter than the CO2, so the chances of contamination are very small.

Current wisdom - just leave it in the primary bucket, rack into bottling bucket?
