President Joe Biden’s Covid-19 Response Team is holding a press conference on Friday on the pandemic that infected more than 27 million Americans and killed at least 475,457 people in about a year.

Biden announced Thursday that his administration had signed contracts with Pfizer and Moderna for an additional 200 million doses of Covid-19 vaccine, bringing the US total to 600 million. Since both approved vaccines require two doses three to four weeks apart, a total of 600 million doses would be enough to vaccinate 300 million people.

In addition to securing more doses for states, the Biden government is using the military to support doses and is establishing mass vaccination centers across the country.

On Wednesday, the government announced it would work with Texas officials to build three new community vaccination centers in Dallas, Arlington and Houston. A few days earlier, the government had announced that it would send troops on active duty to California to help vaccination centers for Covid-19 employees.
