Covid vaccines are not perfect and effectiveness tends to weaken with time.  Vaccinated people are still vulnerable to the deadly disease. The flu is also projected to be widely prevalent this fall and winter. To be safe, monitor your family regularly for fever and speak with your healthcare provider at the first indication of fever. Only Exergen thermometers are proven to detect fever by more than 100 published clinical studies, and beware of noncontact devices that miss five out of six fevers. Remember, vaccines are not perfect so protect yourself and your family with the Exergen TemporalScanner. Learn more at EXERGEN.COM.
