The CDC is reporting that just 4 million COVID-19 vaccine doses have been administered so far in the U.S. - far lower than the number originally predicted.

More than 350,000 people have died in the country from COVID-19 - which is more than the populations of cities like Pittsburgh, St. Louis and Lexington.

Hospitalizations also show no sign of slowing, staying above the 100,000 mark for the 32nd straight day.

In hard-hit Los Angeles, doctors are now warning that this is a big problem for anyone with any medical issue.

Former CNN host and talk show legend Larry King is now among the many hospitalized with the virus. A source close to the family tells CNN that the 87-year-old has been at Cedars-Sinai Medical Center for over a week.

Meanwhile, frustrations are growing over a slower-than-expected vaccine rollout. The government's original goal was to vaccinate 20 million people before the new year.

In Florida, some waited for more than 13 hours to be one of just 600 people given the vaccine. Everyone else was turned away.

A similar scene unfolded in Houston, where Mayor Sylvester Turner says they had so many calls for appointments that it crashed the system.

For those lucky enough to get the vaccine, they'll have to come back in a few weeks for the second dose.

The CDC says more than 13 million doses of the vaccine have been distributed.
