“The FDA, the CDC and the vaccine advisory committee have looked at all of these issues and found that by far, the benefits of getting the Johnson & Johnson vaccine outweigh the risks,” said Dr. Rodger MacArthur, an infectious disease expert at the Medical College of Georgia. He says if you’re concerned about getting the vaccine, do your research. “Talk to friends who have been vaccinated,” Dr. MacArthur said. “Talk to family members. Discuss any concerns you might have about it.”
