SAN FRANCISCO — The ride hailing companies Uber and Lyft have started providing free transportation to and from COVID-19 vaccination sites in the United States.

Uber said Monday that it will provide four rides valued at up to $25 each through July 4 while Lyft has said that it is offering two rides of up to $15 each.

The federal government said earlier this month that it would partner with the ride-hailing companies to encourage more Americans to get vaccinated as the pace of the shots nationally started to decline.

President Joe Biden has set a goal of delivering at least one dose of vaccine to 70% of adult Americans by Independence Day and fully vaccinating at least 160 million by then.
