Coronavirus: Antibodies fall rapidly after COVID infection, dashing hopes of herd immunity - study
Researchers find that the number of people with antibodies in their study fell by 26% since lockdown measures were relaxed.
https://news.sky.com/story/coronavirus-herd-immunity-hopes-dashed-as-study-shows-covid-19-antibodies-fall-rapidly-after-recovery-12115510

Hopes that the population will become immune to COVID-19 have been dashed by new research showing antibodies fall rapidly after recovering from the disease.

So-called herd immunity has been proposed by some scientists as a better alternative to lockdowns in tackling the coronavirus pandemic.

It would require around 50-60% of the population to have protection against the virus so it could no longer transmit efficiently.

However, a major UK study has found that rather than building immunity over time, the number of people with antibodies has fallen by 26% since lockdown was eased over the summer.

Researchers from Imperial College London screened 365,000 people over three rounds of testing between June and September.

Results of the REACT-2 study showed that 6% of people had antibodies to the virus around the time lockdown was eased in late June and early July.

But by the start of the second wave last month, this dropped to just 4.4%.

Professor Helen Ward, one of the researchers, said the new results strongly suggest that herd immunity is unachievable.

"When you think 95 people out of 100 are still likely to be susceptible, we are a long, long way from anything resembling population level protection against onward transmission," she said.

"It's not something you can use as a strategy for infection control [for COVID-19] in the population."

The finding is another blow to scientists behind the controversial Great Barrington Declaration, who had suggested that vulnerable people could be shielded at home while the virus spreads through the young and healthy to build up herd immunity.

The proposal has been strongly criticised by many other scientists.

The researchers found younger people, those from black, Asian and minority ethnic (BAME) communities and health workers had higher antibody levels, possibly because they were in regular contact with infected individuals.

The fall in antibodies suggest people will be regularly re-infected, just as they are with related coronaviruses that cause the common cold.

Professor Wendy Barclay, an infectious diseases specialist and one of the researchers, said antibodies peak three to four weeks after symptoms and then drop away, as they do for related viruses.

She said: "Seasonal coronaviruses that circulate every winter and cause common colds can re-infect people after six to 12 months.

"We suspect that the way the body reacts to infection with this new coronavirus is similar to that."

There have so far only been a handful of documented cases of re-infection.

Dr Alexander Edwards, associate professor in biomedical technology at the University of Reading, said: "What is not clear is how quickly antibody levels would rise again if a person encounters the virus a second time.

"It is possible they will still rapidly respond, and either have a milder illness, or remain protected through immune memory.

"So even if the rapid antibody test is no longer positive, the person may still be protected from re-infection."

The study, which is yet to be peer reviewed, only measured antibodies.

It is possible that another arm of the immune system called T-cells, may remain active, but there is currently no available test for them.

Scientists are cautious about using the results to predict the protection provided by a vaccine.

They say immunisations may lead to a more robust antibody response.

Health Minister Lord Bethell said the study "is a critical piece of research, helping us to understand the nature of COVID-19 antibodies over time, and improve our understanding about the virus itself".

He added: "We rely on this kind of important research to inform our continued response to the disease, so we can continue to take the right action at the right time.

"It is also important that everyone knows what this means for them - this study will help in our fight against the virus, but testing positive for antibodies does not mean you are immune to COVID-19."

It seems to be very exceptional you hear of a double dose, which hardly seems to corroborate this??

If you didn't know you had it first time you might not know you had it second time.

The probably of getting the virus is pretty low to start with. The probability of getting the virus again is also low so you have to multiply the two probabilities together. Which seems consistent with the fact that, so far, not many people have caught it twice.

i had a good chuckle reading we might need  at least a vaccine every year as covid can mutate and come back in different forms. errrm a bit like flu eh?

Antibodies in the bloodstream fall following the resolution of infection as they are no longer needed in huge quantities. The memory of how to make them is retained in immune system cells and the numbers can be restored rapidly if another attack is detected.

Whats it matter? Next year one of two things happens. We either have a decent vaccine and go back to normal or we dont have a decent vaccine and go back to normal. Restrictions were always going to be time limited and that times is running out fast at Italy is showing today.

Healthy population that eats good stuff like kebab pizza all day, walks five miles a day, has low obesity rates and naturally, even without SARS-CoV-2 around, avoids contact with humans they don't know well like the others all have the plague.Happy

The naturally avoiding people like the plague is probably the biggest reason.

You can see it in Germany too. Those nasty southerners that are raised hug each other all day, raised to talk to humans out of their free will, have massive numbers. The people in the region that used to be Swedish, and is still pretty similar in temperament, have some of the lowest number of cases and death per capita you will see in any western European country.

1tp,367 deaths.

thats people who have died within 28 days of being tested positive of covid. could of been knocked over by a car or electrocuted.still counts covid.

this is misinformation and should be stopped

Perhaps you think that they managed to sign all those people up to pretend they are ill and therefore pack out hospital beds, all those doctors and nurses too playing along.

This car crash red herring just isn't significant in the figures. It really doesn't matter for the stats if "only " 365 died of Covid & 2 were hit by a car.

The death certificate deaths with Covid are thousands more than this daily figure. If anything UK (& other countries) are under reporting number of Covid deaths.

Also the stats guys predicted a rise in weekly deaths because of increase in cases, are we supposed to believe they knew about thousands of extra car crashes & predicted them?
Wouldn't the police & insurance companies notice if loads more car crashes every day.

How many people do you think have tested positive & get killed by a car within 28 days?
