If it were me, I would at least go purchase a 5-way and give it to her. Record it, keep the lot number and type "tab" from the shot for your records. Done. You know when your others were last immunized - I would remove all doubt for the new one. If it would give you peace of mind, call your vet and ask him if this is advisable (i.e., "what if" she had them 6 months ago, will it matter).
There is just as much horse sense as ever, but the horses have most of it.
