The Omicron Covid variant “does not provide immunity against reinfection,” the study shows

A study by scientists at Imperial College London has shown that people who have had the Omicron variant appear to have no immunity from being reinfected with the virus

People who have had the Omicron variant appear to have no protection from being reinfected with the Covid strain, a new study has found.

Scientists at Imperial College London have found that while people with the original Covid virus and other subsequent variants had some level of immunity to re-infection, this was not seen in their research on Omicron.

The findings could explain why people who had Omicron caught the variant again quickly afterwards.

The good news, however, is that registered Covid deaths in England and Wales have continued to decline, although the extent of the decline has been affected by the anniversary holiday.

Prof Danny Altmann of Imperial College’s Department of Immunology and Inflammation said that Omicron was able to “fly under the radar” so that people’s immune systems didn’t remember it.

“The message is a bit grim. Omicron and its variants are great at breakthroughs but poor at inducing immunity, so we’re getting reinfections ad nauseam and a severely exhausted workforce,” he said Telegraph.

“Not only can it breach vaccine defenses, it appears to leave very few of the traits we would expect on the immune system.

“It’s more stealthy than previous variants and flies under the radar so the immune system can’t remember it.”

The research found that in those who were triple-vaccinated and had no previous infection, Omicron provided a boost in immunity against previous variants such as alpha, beta, gamma and the original strain – but virtually none against Omicron itself.

According to the Office for National Statistics (ONS), in the seven days to June 3, a total of 186 deaths recorded the coronavirus on the death certificate – a 55% week-on-week drop and the lowest number since July 2021 .

The latest total covers a period encompassing the Queen’s Platinum Jubilee bank holiday on June 2nd and 3rd, when most registry offices were closed.

This means fewer deaths have been registered than would normally be the case.

The holiday-induced disruption in registrations may have exaggerated the week-on-week drop in registrations.

But it is the fifth straight week that the numbers have shown a decline, suggesting that deaths from Covid-19 are continuing a clear downward trend.

It is too early to see any impact on death registrations from the recent slight spike in Covid-19 infections in some parts of the country.

Around 797,500 people in homes in England would likely test positive for Covid-19 in the week to June 2, which is about one in 70, the ONS said.

This is up week-over-week from 784,100, which was also about one in 70.

Infection numbers are estimated to have risen in London, north-west England and south-east England, with early signs of a rise in east England.

In Wales, the number of Covid-19 infections has risen very slightly from 39,600 to 40,500, although both estimates are around one in 75 people and here the ONS describes the trend as “uncertain”.

The increase in prevalence may have been caused by the proliferation of the newer omicron variants BA.4 and BA.5, along with an increase in infections compatible with the original omicron variant BA.1.

However, the BA.2 variant – which caused a record wave of infections earlier this year – remains the dominant strain in the UK.

Separate figures show the recent decline in the number of people hospitalized with the virus may have stalled.

Around 4,602 patients in England had Covid-19 as of June 13, up 12% on the previous week, while the number in Wales appears to have leveled off at around 250-260.

Previously, patient numbers in both nations had been steadily declining since early April following the peak of the Omicron BA.2 wave.

However, they remain well below levels seen in all previous waves of the virus.
