A ceremony commemorating 50 million coronavirus vaccine jabs was held on Thursday by US President, Joe Biden.

The ceremony has come at a time that there are concerns about the emergence of new variants in at least two states.

Biden came into office as President in January 20 and promised to vaccinate 100 million people in his first 100 days in office.

At the moment, Biden said he is on track to exceed that goal as he hits the 37th day in office, as of the time of this report.

In his words, “Today, I am here to report that we are halfway there,” Biden said adding that he would also celebrate the 100th million doses once it is reached.

Three people – a firefighter, a nurse and a pharmacy worker – were vaccinated during the televised ceremony held in the White House on Thursday.

“We are moving in the right direction,” he said, “despite the mess we inherited from the previous administration which left us with no real plan to vaccinate all Americans.”

The vaccination has been going on until last week after severe winter storms across large swaths of the country impacted transportation and led to dozens of vaccination sites to temporarily shut down.

Before the incident, the US was vaccinating on average 1.3 million Americans every day.
