Delaying the 6 month immunizations. Worried.

April

So, first off I am very much pro vaccinations. My son received his 2 month and 4 month vaccinations right on time. However, I had to travel abroad to be with my mom for her surgery and now cannot get back home to Canada till December. My son will be 8.5 months when he receives his 6 month booster. I am worried that he may fall sick. I almost feel

like a bad mom. Did speak with a nurse back home and she said they recommend getting the shot as soon as I return and not to get it here. Anybody has experience with this sort of thing? Did you have to delay but things turned out ok in the end? Please do not argue about the vaccines. I strongly believe I owe it to my son and other kids around him. Thanks.
