Amazon AWS RDS: how to make the database Publicly Accessible to the internet

I have a database running inside AWS, region South America (Sao Paulo) that I could access with no problems from anywhere in the internet.

Then I wanted to create the same database on US East (North Virginia), but I wasn’t able to access it from the internet. I compared creating a database on both regions to see the diferences and noticed the US East region doesn’t list me any VPC to make it available to the internet.

Sout America Region

US East Region

I’ve been trying to create this VPC with subnet DB, etc, but no success! Anybody know what steps I need to do in order to make the database available to the internet?
