One study found that a person has higher levels of antibodies, which reduce the risk of infection.
–
Antibodies against the coronavirus last at least six months and provide protection against a second infection, according to a study by health workers in the UK.
–
Staff at Oxford Hospital are constantly testing for Covit-19 infection and for antibodies that reveal past infections.
–
Because a person has more antibodies, they are less likely to regenerate.
–
Another separate study found that antibodies or immunity from other types of coronavirus can protect against Govt-19.
–
Dr. Infection Consultant Cavid Jeffrey called the Oxford findings “good news” before Covid realized the vaccine.
–
They pointed out that people who have been infected with the virus are given “at least short-term protection” from reinfection.
–
The Oxford study followed more than 12,000 healthcare workers, 11,000 of whom tested negative for the antibody to Covit-19.
–
Antibodies are formed during viral infection, preventing the virus from entering body cells and attacking the immune system.
–
Of those without antibodies at study entry, 89 had symptoms of infection confirmed by TECECA (Wipe with a cloth).
–
Meanwhile, among those who have specific antibodies to the corona virus, none developed symptoms of infection during the study period.
–
Despite the positive antibody tests, three people developed Covit-19 infection without symptoms, compared with 76 in the no antibody group.
–
However, none of the three fell ill.

T-cells from the common cold
The results were consistent with “repeated exposure to SARS-Cowie-2, which did not cause repeated symptoms,” said the study.
–
The antibody studied was the type that binds to the “spike” or sharp tip of SARS-COV-2, which causes infection COV-19.
–
This is a “boom” area that is the target of many vaccines currently being developed.
–
The tested employees were then followed for up to 30 weeks.
–
Earlier this week, a study by the UK government agency, Public Health UK, focused on T cells – another organ of our immune system for infection.
–
A study in June found that a quarter of workers in critical or critical sectors had the highest levels of T cells, which they recognize in their blood as Covit virus – but only half of them have Covit-19.
–
The researchers concluded that this infection may be caused by previous infection with a coronavirus other than the common cold virus “SARS-CoV-2”.
–
And people with high levels of associated T cells “appeared to be protected against Covit-19 for four months of recruitment,” whether they had Covit-19 or not.
–
However Dr. Rupert Peel of the Francis Creek Institute Research Institute “This equates to a very low proportion of the adult population (less than 10%, maybe less than 10%”), who are protected by T cells already present in the immune system.
–
Previous paper suggested that a focus solely on antibodies might overlook many people who are protected from regeneration by T cells – another part of the immune system response.
