â TB Answer: Weâre moving closer to a vaccine against COVID-19 being available widely to the public. Scammers are aware of this and already taking advantage of it. Criminals are becoming increasingly savvy and are always looking to make quick cash through a variety of scams and phishing tactics often targeting the elderly. The scam you mention is one of the latest. Calls appear on your caller ID to be coming from the Centers for Disease Control (CDC) to request donations. Itâs possible to make the call look as though itâs coming from a federal agency because there are downloadable apps that make it easy for someone to make a call appear to be coming from another phone number. Remember, federal agencies do not request donations from the general public.
