(CNN)Could wearing a Covid-19 vaccine sticker after you get vaccinated really encourage other people to do the same?
Experts and the US Centers for Disease Control and Prevention hope that's the case.
"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.
The CDC designed two Covid-19 vaccine stickers to encourage health care workers to wear them after getting vaccinated. There's an orange and a white version that say, "I got my Covid-19 vaccine!"
Malaty Rivera specializes in translating complex scientific concepts into accessible information. She is the science communication lead at the Covid Tracking Project, a volunteer organization that compiles state-level coronavirus data.
"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."
She said other research has shown how bracelets have been used to help parents keep their children on a vaccine schedule in developing countries.
After nurse Sandra Lindsay became the first person in New York to receive the Covid-19 vaccine Monday, she donned a white and green sticker on her scrubs. "Crushing Covid-19. Got my vaccine," the sticker read.
"I feel hopeful today, relieved. I hope this marks the beginning of the end of a very painful time," she said in a press conference.
