Getting Another Dog After Losing One to Parvo?

I recently lost 2 Boston Terrier pups to parvo. They had their shots, and were 7 months old. They had gotten loose and went to the neighbor's yard, where the neighbor had already lost 2 pups to parvo, and has had several cases of parvo over the past 5 years; I found out.

We can quarantine the areas off so no person or animal can get to those areas, we bleached them, sun baked the bleach for 10 minutes (full strength), and then flooded the area with water. We have bleached our carpets, and bleach steam cleaned our hard wood floors, all concrete has been bleached, this process is being done every 30 days to make sure we kill off any Parvo in these areas.

How long before we can get a new Boston Terrier? We miss them so much. I gave them IVs, shots, Pedialyte, and Greek yogurt, but they only survived for 3 days. Any current information would be helpful. Thanks.
