MOORPARK (CBSLA) — Ventura County was forced to shut down two of its COVID-19 testing sites because supplies have run out.

The county shut down testing sites at Moorpark and Oxnard colleges at about 2:30 p.m., according to a tweet.

The shortage in COVID-19 testing supplies is a nationwide issue, as public health officials begin to roll out vaccinations amid a spike in new infections, hospitalizations and deaths across the country.

Ventura County says its testing sites at the Ventura County Fairgrounds and in Santa Paula remain open.
