Anyone has their 2 months vaccination done yet ?

I'm considering splitting the number of vaccines and only give 2 per visit once every 2 weeks . Anyone has done the same ? 
Also , considering not to vaccinate for Hepatitis B since he already had one at birth. 
Please share your thoughts on this , I want to be informed before our appointment , I'm also doing my research . Pease feel free warn me if you think some of the vaccines are dangerous .
