But two new scientific studies have discovered that those antibodies start to fade very, very quickly.
For example, a study that was recently conducted in China found that more than 90 percent of COVID-19 patients experience steep declines in COVID-19 antibodies “within 2 to 3 months”…
A new study from China showed that antibodies faded quickly in both asymptomatic and symptomatic COVID-19 patients during convalescence, raising questions about whether the illness leads to any lasting immunity to the virus afterward.
The study, which focused on 37 asymptomatic and 37 symptomatic patients, showed that more than 90% of both groups showed steep declines in levels of SARS-COV-2–specific immunoglobulin G (IgG) antibodies within 2 to 3 months after onset of infection, according to a report published yesterday in Nature Medicine. Further, 40% of the asymptomatic group tested negative for IgG antibodies 8 weeks after they were released from isolation.
And a very large study that was just conducted in Spain found that some patients that had initially successfully developed antibodies “no longer had antibodies weeks later”…
A large study from Spain showed that antibodies can disappear weeks after people have tested positive, causing some to question how possible it will be to attain herd immunity.
A study published in medical journal Lancet showed 14% of people who tested positive for antibodies no longer had antibodies weeks later.
Needless to say, this is absolutely devastating news, and it has very serious implications for vaccine development…
