ATLANTA — Thousands of infectious disease experts are at the Georgia World Congress Center in Atlanta for the annual convention, IDWeek, and vaccines are a hot topic.

It’s the largest annual meeting of experts to trade information about diagnosing, treating and preventing threats from super-bugs to measles to HIV.

Dr. Sean O’Leary from the University of Colorado School of Medicine says many times it’s access to vaccines that’s a bigger problem than vaccine hesitancy.

“Vaccine hesitancy remains a major threat to public health. It may be growing. It’s highly contextual. But remember that our overall vaccination coverage remains high,” says O’Lear.

He says presumptive recommendations tend to work best when it comes to vaccinations.

Lori Handy from the University of Pennsylvania School of Medicine tells healthcare providers politics have to be off the table during the discussion.

CDC researchers are skipping the conference due to the government shutdown.
