Amazon takes another shot at health care, this one a virtual care service that costs $9 per month

Amazon is taking another shot at becoming a regular health care source for customers with the launch of a service centered on virtual care.

The e-commerce giant says its Prime customers can now get quick access to a health care provider through a program that costs $9 a month or $99 annually.

The announcement arrives less than a year after Amazon announced the $3.9 billion acquisition of the membership-based primary care provider One Medical, which has medical offices in more than 20 markets.

The company has made a number of attempts to incorporate healthcare into its platform and has started building momentum after some initial setbacks.
