In brief: Yes and no

A small percentage of vaccine recipients can and do break out a week or more after varicella vaccination.
This is not the wild chickenpox but a manifestation of the weakened vaccine virus. Most have fewer than a dozen lesions, compared with an average 200-250 with wild chickenpox. Such an event does provide longlasting protection from the wild chickenpox.
