Will buy 100 million additional Johnson and Johnson vaccine doses, US President Joe Biden on Wednesday came back to the MIC to make a pledge.

If we have a surplus, we're going to share it with the rest of the world.

Speaking to reporters alongside the CEOs from Johnson and Johnson and Merck, Biden said vaccinating Americans is the only way to beat the pandemic and that Americans will get access to the vaccines first.

But if there are extras the United States will share, this is not something that can be stopped by a fence, no matter how high you build a fence or a wall, so we're not going to be ultimately safe into the world is safe and so we're going to start off making sure Americans are taken care of first.

But we're then going to try to help the rest of the world.

The World Health Organization has long called upon rich countries to ensure that vaccines are shared equitably.

Biden said that on Saturday the US hit a new record of 2.9 million vaccinations in one day.

He reiterated that his administration is on track to have enough doses to vaccinate all American adults by the end of May.

Biden plans to make a primetime address on Thursday detailing the next phase of the government's covid response and what will be asked of the American people.

There is light at the end of this dark tunnel in the past year.
