Whether you’re worried about getting a COVID-19 vaccine or are already inoculated and want to help sway your hesitant friends and family, it may help to know the science behind some common vaccine fears and misconceptions.

Daniel Salmon is the director of the Institute for Vaccine Safety at Johns Hopkins School of Public Health, where his research focuses on vaccine safety and factors that influence vaccine acceptance.

The institute’s website, vaccinesafety.edu, centers on providing objective, up-to-date information on vaccine safety. However, Salmon acknowledged that it’s been a challenge combating the misinformation that’s helping to fuel COVID-19 vaccine hesitancy.
