Ben Osborn, national director of the UK pharmaceutical company, said it was still unclear whether they would be required every six months or annually.
His remarks come on the anniversary of the first Pfizer vaccine given as part of a mass immunization program – for Marguerite Keenan, a 91 year old grandmother who has since suffered a second and third jab.
Mr Osborn said the UK campaign has been an ‘incredible undertaking’, while the Prince of Wales and the Duchess of Cornwall paid tribute to the “remarkable ingenuity and determination” of those involved.
Charles and Camilla confirmed that they have both received their booster, saying: “We urge everyone to get vaccinated and take the booster, just like we did ourselves. “
“To all those who have not yet had the vaccine – or who are hesitant to receive a booster – we can only urge you to look at the evidence in our intensive care units and to listen to those who work there,” said they added.
Some 6.4 million – 11% of the population – across the UK have yet to have their first COVID-19 vaccine.
Mr Osborn said giving booster shots to all adults is the most important thing that can be done to fight the Omicron variant at the moment.
He said Pfizer is ready to develop a new vaccine if needed and would be able to produce doses “on a large scale”.
“We are all waiting for the release of various data, not just from Pfizer and BioNTech, but from governments and healthcare systems around the world,” he said.
He said the company was trying to understand ‘the level of transmission this new variant gives and whether it will outperform Delta here in the UK’, its impact on hospitalizations and deaths, and how it is impacted by the vaccine.
More data on these factors will be available in the coming weeks, he said.
Asked how long people should expect to need boosters, he said: “I think it’s hard to say in terms of many years because neither of us can predict how the virus will progress over time. time.
“I think what the science and the data are showing us now is that we’re probably going to need some level of strengthening in our adult population for a number of years to come. “

He said Pfizer is also set to provide vaccines to children as young as five – something already happening in other countries – if the UK drugs regulator approves the company’s request.
Since the UK vaccination program began a year ago, just over 51 million first doses of the vaccine have been administered, along with over 46 million second doses and 20 million boosters.
Mr Osborn said: ‘I don’t think anyone would have imagined that we would be in the position that we are today here in the UK, where we obviously have over 80% of our population on two doses, and we are now in the reminder program. ”
