More than 2.9 million Hoosiers are fully vaccinated according to the Indiana State Department of Health.

The state said just more than 2,700 people have caught COVID-19 after being fully vaccinated, meaning less than 0.1% of fully vaccinated people in Indiana have been infected with the virus. While that percentage is low, concern among health leaders is growing.

WISH-TV medical expert and former U.S. Surgeon General Dr. Jerome Adams emphasized that vaccinated people are better prepared to protect themselves from severe disease and hospitalization and is not surprised to hear about breakthrough cases, like in the case of Indianapolis Colts Head Coach Frank Reich. He tested positive for COVID-19 after being fully vaccinated.

“What vaccines are designed to do is train your body, just like the Colts train in practice so that when you meet that enemy in real life, you can fight that enemy. It doesn’t mean the enemy is not going to come, it doesn’t mean you are not going to be still assaulted by COVID – especially as we see cases going up and it doesn’t mean it is not going to take a while for you to fight that back, which is when you might test positive, but it does mean you are more prepared to protect yourself against severe disease and hospitalization. So Frank’s vaccine did exactly what it is supposed to do and it’s why we need more people to get vaccinated so they can protect themselves,” said Adams, who was also Indiana’s Health Commissioner from 2014-2017.

Adams said the biggest thing to pay attention to is whether or not you go to the hospital with the virus or die from it.

“Still 90% effectiveness from these vaccines, even in the midst of the Delta variant, against severe disease and hospitalization. So, we are going to see some breakthrough infections in terms of people testing positive, but we are not seeing very many, very many at all breakthrough infections from the standpoint that people are getting really sick,” said Adams.
