As for the spreading of STIs...education is the key here not RIC. I have no control over what my son does when he reaches that stage in life but do hope I would have taught him enough about the importance of protection. They mentioned the risk factors with penile cancer in the article are so low that they're negligible whether the boy is intact or circumcised. The instances of UTIs can be reduce through proper care and hygiene though there will still be some cases no matter what.
I'm with others who have commented though. Comparing RIC and vaccination is ludicrous. There are other much more effective ways to prevent the spread of STIs and this is the only way that RIC would impact anyone else's health. Vaccinating is the only way to stop the spread of VPDs and they definitely impact of the health of others.
