According to official statistics, more over-80s are now carrying Covid antibodies than ever just two years after the booster rollout started.
According to the latest Office for National Statistics Blood Testing Study, 95.8% of those over age 80 were tested positive for proteins in November 7.
Since December last year, the sample collection began at 2.8 million. This record is the highest ever.
The number is slightly higher that when the second doses of anti-Bacterol were given to patients over 80 in May. 94.4 procent had antibodies.
Launched on September 16, this booster campaign targeted first elderly Britons.
However, the 16-24-year-olds currently have the highest antibodies levels. In fact, 96.1 per cent of them tested positive for the disease in their most recent week.
The immune response to Covid includes the formation of antibodies. These antibodies generally indicate that someone is at least partially protected against the virus.
The first rollout targeted over-80s and boosters, as they were most likely to be hospitalized or die from the virus.
After receiving their second dose, 79% have received their booster. Bookings were made starting six months after the first dose.

This graph illustrates the Covid antibody (blue Line) in over-80s. It also shows how many have been vaccinated (pink Line) with at least one dose.

Below is a graph showing the percentage of Covid antibody-positive people over the past week, sorted by age.
As part of this project, the ONS conducts blood tests every week to randomize test 30,000 individuals for antibodies.
Antibodies bind to the spike protein of the virus — which it uses to invade cells — preventing an infection.
These substances are often found in blood after an infection or vaccination, but they disappear slowly.
The T cells are more difficult to detect as they are memory cells that store data on ways to combat a virus after the antibody levels have diminished.
Since October’s start, antibody levels in over-80s has been increasing week-on-week. They reached a low point of 87%.9 percent.
The vaccine takes two weeks to reach effect after the booster drive has ended.
The latest antibody levels are now up 1.4% from two weeks ago and 3.1% from one month ago.
It is also believed that more people over 80 in Scotland have Covid antibodies.
According to the latest estimates, 92.3 percent have these now.
The level in Wales was at 91.3 percent, an increase of 76.1 percentages from the beginning of the month.
In Northern Ireland, over 70s had an estimated 89.7 percent of Covid antibodies, as compared with 84.7 percent a month earlier.
At 95.8 percent, the England over-80s are home to the highest number of Covid fighting antibodies.
The highest percentage is found in 16-24-year-olds, which are 96.1 percent. However, they have not been offered boosters.
Separate numbers show that infection rates in the older age groups are several times greater than those of older adults. This could indicate that immunity is higher.
Britain provides booster doses of a second dose to people over 50 since September. These can be obtained from six months later.
After many seniors complained that they couldn’t find the right place to obtain the next dose, bookings opened five months later.
Over-40s were also welcome to take part in the extra jabs, as it was opened up to other age groups.
Ministers suggested that every person could eventually be given a boost dose.
Britain currently produces 348,000 boosters per day. This is more than triple the pace of September’s drive.
The company has already distributed 15.3 million top-up dosages. This puts it far ahead of European counterparts.
In the UK, 22% of booster-infected people are almost double the rate in Austria (13%), and 3 times that in Germany (7%)
