Doctors warn CDC to tell public about side effects of COVID vaccines, number of doses needed

Doctors warn CDC to tell public about side effects of COVID vaccines, number of doses needed: 

The first COVID-19 vaccines might be around the corner, but the side effects won't be a walk in the park, doctors say. That could be a problem given that both of the first vaccines likely to arrive on the market require doses to be given twice. This isn't unusual for a vaccine, but it presents a logistical challenge for an inoculation intended to stop a pandemic.
