The White House Coronavirus Task Force is calling on states to push ahead with vaccinations, particularly among senior citizens, according to a new report obtained by ABC News.

States should not "delay the rapid immunization of those over 65 and vulnerable to severe disease," the report said. It also recommended creating vaccination sites with EMTs on hand to deal with any allergic reactions and using nursing students to help with the rollout.

"No vaccines should be in freezers but should instead be put in arms now; active and aggressive immunization in the face of this surge would save lives," the memo said.

Operation Warp Speed officials announced on Tuesday that 19,141,175 vaccine doses have been delivered so far. The U.S. Centers for Disease Control and Prevention's data shows 17,020,575 doses have been distributed and 4,836,469 Americans have received a dose.

COVID-19 deaths in Los Angeles County have reached 11,000 as hospitalizations have increased to critical levels, according to Los Angeles County health officials.

As of Tuesday, officials identified 840,611 positive cases of COVID-19 across all areas of L.A. County and a total of 11,071 deaths.

Dr. Barbara Ferrer, L.A. County Director of Public Health, said the county must continue to wear masks and social distance and not just wait for the coronavirus vaccine.

"As a community, we must commit to stopping the spread of COVID-19 in its tracks so that we can save as many lives as possible. Roll out for COVID-19 vaccine continues in the phases recommended by the State and CDC as supply allows," Ferrer said in a statement Tuesday. "And while vaccines are a powerful tool, we do not need to wait for vaccine to stop new COVID-19 cases, hospitalizations and death. We can do that now.

"It takes every business and every resident to purposefully follow public health directives and safety measures. Please stay home and leave only for essential work or essential services," Ferrer said.

The county reported 224 new COVID-related deaths Tuesday along with 13,512 new cases. L.A. County has had more than 1,000 new COVID-19 deaths in less than a week, according to health officials. There are a record 7,898 people hospitalized with COVID-19 in L.A. County and 21% of those are in intensive care units.

"Health care workers and hospitals continue to be taxed and overwhelmed with COVID-19 patients," the L.A. County Health Department said in a statement Tuesday. "The devastating impact of the pandemic is disrupting emergency medical care due to the sheer volume of COVID-19 patients and staffing limitations. These challenges will get worse if we don’t slow COVID-19 spread."
