âFalse sense of securityâ: Study finds some thermal imaging temperature checks show inaccurate readings By Kelly Hayes What we know about children and COVID-19 vaccines When will children be able to get COVID-19 vaccines? It depends on the child's age, but some teenagers could be rolling up their sleeves soon. Since the onset of the coronavirus pandemic, many people have undergone thermal imaging temperature checks at schools, airports, workplaces and even sports venues — part of a larger approach to help lower the risk of COVID-19 in these public areas. But researchers behind a new study say some of these devices show inaccurate temperature readings, with some reporting fever-level temperatures as normal, which could further lead to a "false sense of security."
