Boris Johnson has announced that a memorial to Covid victims will be constructed.
The PM said that a "fitting and permanent memorial" would be built for those who have lost their lives.
"At the right moment" it will be built and the "whole period" will be commemorated, he said.
Johnson told the Downing Street press conference: "At the right moment, we will come together as a country to build a fitting and a permanent memorial to the loved ones we've lost and to commemorate this whole period.
"For month after month, our collective fight against coronavirus was like fighting in the dark against a callous and invisible enemy until science helped us to turn the lights on and gain the upper hand."
Johnson was speaking at a No10 press conference a year after the first lockdown began.
He is accompanied by Chief Medical Officer Professor Chris Whitty and the Chief Scientific Adviser Sir Patrick Vallance.
Sir Patrick said that booster Covid-19 jabs could be needed in the autumn to prevent another wave of infection, although he added that there were no indications that the level of protection offered by the shots was waning.
"There will be a need to think about booster jobs for vaccines in the autumn I suspect, particularly thinking about getting high level of immunity to cover things over the winter," he said.
The press conference comes on a day in which 112 more Covid-19 deaths were suffered in the UK.
The brings the country's pandemic total to 126,284, the fifth highest death toll in the world and by far the highest in Europe.
Johnson said lessons will be learned for future pandemics, as he was asked whether the Government should have imposed lockdown sooner.
He said: "These are very hard decisions and there are no good outcomes either way.
"All these consequences are very tough for people and all I can say is we took all the decisions with the interest of the British people foremost in our hearts and in an effort to protect the public and prevent death and suffering.
"Though doubtless there will be a moment to properly review, to learn lessons for future pandemics of a kind which I'm sure there will be."
Sir Patrick said having adequate testing in place at the beginning of the pandemic would have made a "big difference".
"The one thing that I think would have been really important earlier on is to have much better data on what was happening," he said.
"And that would have required testing to be up and ready immediately and it would have required the ability to get that information into a source and to be able to see it.
"We simply didn't have that at the beginning and it was very difficult to know the speed at which things were moving and therefore make decisions based on the real-time data which we can do now and that would've made a big difference."
On this date a year ago, when the first national lockdown began, 76 people died - the last time daily deaths were not in the hundreds for more than two months.
The PM commemorated those who have lost their lives to the virus and paid tribute to NHS workers.
Yesterday Johnson warned that another wave of cases that are starting to envelop parts of mainland Europe will likely "wash up" on UK shores.
Several hours after Johnson and the advisors leave the stage, at 8pm Brits have been encouraged to take part in a doorstep vigil, using candles, torches or phones to light up a beacon of remembrance.
Labour leader Keir Starmer said he would be joining the minute's silence to remember those who have died.
He tweeted: "As we mark one year since our country entered the first lockdown, my thoughts are with all those who have lost loved ones since the pandemic began."
