Yes. Once there is alcohol to fight infection, the risk goes down. However, the risk also goes up for oxidization and other baddies because once fermentation is complete, there isn't a ceiling of CO2 to protect what lies beneath. And, of course, if your bottles are nasty, then your beer will be nasty too. The alcohol may prevent you from getting sick, but it will still affect taste, etc.
Tried to keep up with this signature, but just couldn't.
