Get some protection
The incubation for chicken pox is about 10-21 days (time of contact to development of disease), and vaccine results in some immnity as early as 10 days as well and excellent by 3 weeks time.
So, in your case, you will likely get some protection. However, it is a good chance that you are already immuned to it..Likely exposure to it when u were younger..Consult your doc. Good luck.
