Study: COVID Antibodies Last More Than a Year After Infection
The immune systems of the vast majority of people who have been infected with the CCP virus will continue to carry antibodies against the virus for at least 12 months, according to a peer-reviewed study accepted by the European Journal of Immunology on Sept. 24.
Scientists at the Finnish Institute for Health and Welfare studied the presence of antibodies in 1,292 subjects eight months after infection.
They found that 96 percent of the subjects still carried neutralizing antibodies and 66 percent still carried a type of antibody called nucleoprotein IgG.
The scientists then investigated antibody levels one year after infection by randomly selecting 367 subjects from the original cohort who hadn’t yet been vaccinated.
Eighty-nine percent of the subjects still carried neutralizing antibodies, and 36 percent still carried the IgG antibody.
Antibody levels were higher in subjects who had experienced severe COVID-19 disease.
Compared to those who had mild disease, these subjects had two to seven times as many antibodies for at least 13 months after infection.
“Studies of individuals who have recovered from [CCP virus] infection are crucial in determining for how long antibodies persist after infection and whether these antibodies protect against re-infection,” the scientists wrote (pdf).
Despite lasting protection against the original strain of the CCP virus, the study found that the neutralization efficiency against the Alpha, Beta, and Delta variants waned over time.
The reduction in efficiency was “considerably declined” for the Beta variant and was “only slightly reduced” against the Alpha variant.
For the Delta variant, which is the dominant strain in the United States, the study found that 80 percent of the subjects still had immune protection 12 months after infection.
A study published in Nature Medicine in May found that the levels of neutralizing antibodies in a person are highly predictive of immune protection against infection and severe disease caused by the CCP (Chinese Communist Party) virus, commonly known as the novel coronavirus.
Prior studies have shown that antibodies persist six to 12 months after infection.
Despite the robust and lasting protection after an infection, CCP virus vaccine mandates in the United States offer no exemptions based on acquired immunity.
An Epoch Times review of vaccine mandates for U.S. colleges and universities didn’t find a single school offering exemptions to students who had acquired immunity.
Recent mandates imposed on the state and federal level have likewise ignored acquired immunity.

Sorry to say, but even the title is a complete nonsense! A study for a ‘totally new’ virus which exists ~ 1.75 year finds that the antibodies against it ‘last’ 1 year???? Todays’ science morons indeed completely erased the innate immune system in HUMANS!! Who pays them? Gates and WHO?

Here is the ingenuous problem with this study. Sure C-19 antibodies might be around for a few months, but thinking that immunity is based on circulating antibodies is simply ignorant and uneducated thinking. We do NOT waste our metabolic energy maintaining antibodies against everything we are ever challenged with. Antibodies drop off with times but the immune (T) cells that make this antibodies are always ready to detect the pathogen and start pumping out the correct antibodies. Duh.
This might be like noticing that the heat in your house drops of with time (and panicking) and not recognizing that, when it gets cold enough, the heating system kicks in.
Thinking that antibodies are long term defense is simply either ignorance of how the immune system works or a purposeful denigration, by lying, of how it works.

I was very sick for about 8 days ( early in “pandemic”) but not hospitalized. Well over a year on now, I still have antibodies circulating in me -detected in blood work draw on July 13, 2021. My doctors office said you may not have enough ,get vacs! I showed them four recent reputable studies showing memory cell mechanism protection for COVID 19 ( as well as the fact that it is established science in virology) basically I was more informed than they were!
