The Trek to Elysium Chronicles by Hugh Williams

This book is the first of three than I plan to write for this series. It tracks the travels of myself and 3 friends as we attempt to escape the Zombie apocalypse. The story is initially set in Southern Illinois, Carbondale to be specific, as that is where I currently live. The apocalypse was caused by a combination of factors. One was our government allowed people with the Nova virus to come to our country to get help. We are still the only country that allows that. Second, a corrupt (are there any others) mega corporation that was given a huge government contract to perfect a vaccine to cure Nova allowed the vaccines to become contaminated. Millions of people took the vaccine and I think the reader will figure out what happened as a result of the contamination.
