INDIANAPOLIS (WISH) – The US Centers for Disease Control and Prevention has released new evidence that the mRNA vaccines are five times more effective at preventing hospitalizations than natural immunity, with Moderna doing slightly better.

However, a new study by scientists in Israel emphasizes that it is the other way around. Natural immunity, they say, is the clear winner, offering 13 times more immunity than vaccination.

News 8 spoke to Dr. Shaun Grannis, vice president of data and analytics at the Regenstrief Institute in Indianapolis. Grannis first weighed in in the CDC study. “I think this study provides good evidence all around and I think the reassurance that the vaccine offers more protection than natural immunity,” he said.

Grannis then offered thoughts on the Israel study. Although it is a valid study, he says. it is impossible to compare the two. “The United States has a different population distribution. other comorbidities than Israel (and) is a younger country. So there are a number of other demographic factors that are different.”

Examples of comorbidities include heart disease, high blood pressure, and obesity. More than 18 million Americans have heart disease. Nearly half of the population has high blood pressure. Nearly 70% of the nation is overweight or obese. This is why Grannis prefers the CDC study over the Israel study.
