Coronavirus study from China: 285 Covid-19 patients developed antibodies to the virus
A study at China’s Chongqing Medical University, where the coronavirus outbreak began, found that 95 percent of 285 coronavirus (Covid-19) patients developed immune cells of both types fighting the virus.
An investigation into the outbreak was carried out at China’s Chongqing Medical University, where the coronavirus outbreak began.
Researchers at Chongqing Medical Center monitored the blood of 285 Covid-19 patients for signs of immune cells. Antibodies are immune cells that the body uniquely develops in response to a particular pathogen.
If no virus or bacteria like the one that caused Covid-19 have been encountered before, the body has no antibodies against it. In response to most infections, the body begins to produce these special ‘weapons’ that will recognize and target an infection if it is encountered again.
2 TYPES OF ANTIBODIES PRODUCED AGAINST INFECTIONS
British media reported that 2 types of antibodies were produced against infections, including immunoglobulin M (IgM) and immunoglobulin G (IgG), while IGM was produced at an early stage after infection. It was stated that the IgM antibodies provided brief protection before gradually disappearing and that only 40 percent of patients developed IgM antibodies within the first week after infection.
DEVELOPING ANTIBODIES AGAINST THE VIRUS
On the other hand, while patients were under observation for 2 weeks, 95 percent of the patients developed antibodies at detectable levels. More importantly, they all developed IgG antibodies, which are the type with long-term protection potential and take longer to develop. In a subsequent study, it was stated that the researchers took blood from 69 other patients and produced antibodies within 20 days.
