“I definitely think that public health swag has some weight,” infectious disease epidemiologist Jessica Malaty Rivera told CNN. “The flu vaccine band aid has become iconic. Something similar like that for Covid-19, like a button or a sticker, would be something that I would personally wear proudly and encourage others to as well.”

Research shows that visual displays of public health measures are a good thing, from normalizing getting the flu shot to wearing a mask to prevent the spread of coronavirus. As the United States started vaccinating health care workers this week, some hope something as simple as a sticker may help spread the message to get vaccinated…

“There’s definitely psychology to it,” Malaty Rivera said. “The ‘I got the flu shot’ sticker for health care providers definitely gives patients and people coming hospital settings some confidence that they are entering places that are safe and protected.”
