In an attempt to demonstrate trust and reassurance to the people of America about the safety of the COVID-19 vaccines, US President Joe Biden, on Friday, visited a production plant of the Pfizer vaccine in the US.   

Biden, who has prioritised the curbing of the COVID-19 pandemic after taking office on January 2021, cleared any doubts in the minds of the American people about the safety and efficacy of the jabs. 

While giving a brief address at the manufacturing plant in Michigan, he said, "The vaccines are safe. Please, for yourself, your family, your community, this country, take the vaccine when it's your turn and it's available. That's how we beat this pandemic," with confidence.

Biden said companies making the vaccines are "fastidious" and "it takes more time to do the check for safety than it does to make the vaccine. That's how fastidious they are."

"If there is one message to cut through to everybody in the US, it is this: Vaccines are safe," he stressed.

Biden said the program to deliver the vaccines into people's arms is as complicated as the already intense challenges of manufacturing in huge quantities at speed.

Biden compared the difficulty level of production of the vaccine and safely administering it and hinted that it was at par. 

"There has never ever been a logistical challenge as consequential as what we are trying to do, but we're getting it done," he said.

Biden was optimistic about his set goal of inoculating at least 100 million people in the US in his first 100 days as the President, which seems like an attainable achievement with an average of 1.7 million daily inoculations in the US.

With the death count soon set to breach the 500,000 mark in the United States, Biden said he did not want to provide any firm predictions of when the crisis will be over.

However, he said that 600 million doses -- enough to cover most of the country -- were expected to be ready by the end of July.

"I believe we'll be approaching normalcy by the end of this year. God willing, this Christmas will be different to last, but I can't make that commitment," he said.
