Guys, can you imagine, Yale university are using psychologists to study what public messages to use to convince/presuade people to take covid-19 vaccine once it is ready! This is pathetic !
,,Official Title: Persuasive Messages for COVID-19 Vaccine Uptake"
,,This study tests different messages about vaccinating against COVID-19 once the vaccine becomes available. We will compare the reported willingness to get a COVID-19 vaccine."
