One in five severe or fatal Covid-19 cases in UK due to under-vaccination

More than 7,000 people were hospitalised or died from Covid-19 in the United Kingdom during the summer of 2022 because they had not received the recommended number of vaccine doses.

This is according to a study released Jan 16 (2024) that was the first to cover the UK’s entire population.

The researchers said the “landmark” population-wide study showed how important it is for people to keep getting booster jabs as Covid-19 continues to pose a major health threat.

More than 90% of the UK’s adult population were vaccinated during the earlier stages of the pandemic.

However, between June to September 2022, after the pandemic’s emergency phase was declared over and attention turned elsewhere, around 44% of Britons were under-vaccinated, the researchers said.

Using individual health data from the UK National Health Service (NHS), as well as modelling, the researchers estimated that there would have been 7,180 fewer hospitalisations or deaths if everyone had been up to date with their shots.

That means that nearly 20% of the 40,000 Covid-19 hospitalisations or deaths over the summer could have been avoided if Britons were fully vaccinated.

Lead researcher and Health Data Research UK chief scientist Professor Dr Cathie Sudlow told a press conference that the results clearly showed that “being fully and properly vaccinated is good for individuals and good across society”.

The research, published in the Lancet journal, used secure, anonymised health data of everyone over the age of five across the UK’s four nations.

The researchers said it was the first time such a study had included all 67 million people in the UK. They called for the same approach to be deployed in other health research areas, such as cancer, diabetes and heart disease.

“We think this landmark study really sets a line in the sand to say this sort of thing is possible – we need to be doing more of it,” said study co-author Prof Dr Angela Wood from the University of Cambridge.

The UK is uniquely suited to carry out such population-wide research because “virtually every interaction” with the UK NHS is recorded, said co-author Prof Sir Dr Aziz Sheikh from the University of Edinburgh.

“There’s nowhere else in the world that can do this,” he added.

The under-vaccinated tended to be male, younger, non-white, from a more deprived background, and have fewer existing health problems, the study said.

The recommended number of Covid-19 vaccine doses has changed over time and varies between countries.

The UK recommendation in June 2022 was one shot for those aged five-11 years, two for 12-15 years, three for 16-74 years and four for people over 75 years.

Last week, the World Health Organization (WHO) warned that transmission of Covid-19 increased in December (2023), fuelled by gatherings over the Christmas holiday period.
