Halloween with a Newborn?

This is my first little one and our wedding anniversary is on Halloween but we don't really have the money to do anything this year we still are trying to decide but honestly I would love to just be able to tag along while my siblings trick or treat my (husband and I are 19 and 20 but my siblings are all 12 and younger) but my question is would it be totally irresponsible to go with our newborn (a week and a half old) since she hasn't had any shots yet but the weather is decent? It hasn't been cold at all and the weather is showing it will be between 70-80 on Halloween.

I kind of feel like it might be fine but a part of me feels like I don't know if I should take the chance of her getting sick somehow maybe from walking around a bunch of people. Obviously I wouldn't be taking her to doors or anything but our family is really close so it would be nice to just go with my step mom nana, and siblings and to get out of the house.

Opinions are fully welcome I'm just not quite sure how to do things like this with a newborn since this is my first child.. I just don't want to make a bad decision or feel too worried if it's really not that big of a deal..
