State officials are offering tips on how to avoid potential scams when entering Ohio's Vax-a-Million campaign.

The contest gives vaccinated Ohioans a chance to win either $1 million or a full-ride college scholarship.

The Ohio Department of Health is reminding people there are only two ways to enter Vax-a-Million: online at ohiovaxamillion.com and by phone at 1-833-4-ASK-ODH (1-833-427-5634).

Officials say not to follow suspicious URLs or call other phone numbers to enter. Also, do not provide social security numbers or other private information.

The ohiovaxamillion.com registration asks for basic contact information including name, email address, phone number, date of birth and where you received your vaccination. 

It's free to enter the drawings, and people will not be asked to provide credit card or bank account information to enter.

When it comes to the drawings, health officials say people will hear about them in many ways including by email, news coverage, messages to Ohio Lottery text message subscribers (from number 91011) as well as messages from local health departments or business organizations.

Officials say the following are signs that the message you received may be suspicious:
Misspelled words
Incorrect grammar
References to a "sweepstakes"
The "from" email address looks suspicious
The URL listed is not ohiovaxamillion.com, or when you hover over the URL with your mouse, a different URL appears
The phone number listed is not 1-833-4-ASK-ODH (1-833-427-5634)

People can contact the Ohio Department of Health's Call Center at 1-833-4-ASK-ODH (1-833-427-5634) if they have questions about an email, text message, social media message or phone call.

Officials say millions of Ohioans have entered the Vax-a-Million drawings.
