Is it normal for a vesicular rash to erupt 7-10 days at the site of varicella vaccination in a 15 month old? The overall size of the rash is 1cm.

In brief: Yes it can be

Varivax is a live virus vaccine.
The incubation for natural chickenpox is 10-21 days. To have a little chickenpox rash at the site of the vaccine 7-10 days afterwards does happen in about 10% of cases. Some will develop mild chickenpox and break out all over the body.

The virus in the vesicles is the weakened varicella virus, not the wild form.The material from the sores could pass the weakened virus if ingested but the effect on the recipient would likely be unnoticed.
