Fading Antibodies … So Much for a Covid-19 Vaccine! By Brian Simpson

     Cry your heart our Mr Vaccinate-the-Globe Bill Gates. It seems that he antibodies produced against Covid-19 fade, which makes production of a vaccine extremely difficult. Still, one way of looking at this from old Bill’s perspective is that at least there will be an infinite chain of vaccines needed, forever, ensuring maximum profits, if the people play along!

“Over the past several months, there has been a tremendous amount of debate about almost every aspect of the COVID-19 pandemic.  People have been eager to debate about the severity of the virus, they have been eager to debate about the wisdom of the lockdowns, and they have been eager to debate about the effectiveness of wearing masks.  But the one thing that everyone could pretty much agree on is that eventually this pandemic would end.  Virtually all of us assumed that one way or another eventually most of the population would develop COVID-19 antibodies and that once we got to that point the pandemic would fizzle out.  Unfortunately, it appears that was not a safe assumption to make. Yes, those that have had COVID-19 do develop antibodies. 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… Such findings have implications for vaccine development, since the efficacy of a vaccine hinges on the idea that a dose of weakened or dead virus can prompt your body to generate antibodies that protect you from future infection. If those antibodies are fleeting, a vaccine’s protection would be fleeting too. Short-lived antibodies also diminish hopes of achieving widespread or permanent herd immunity.”


     Covid-19 is the bug that just keeps on giving, a gift from the Dark Side. And, the latest fear is a mutated version, allegedly 30 percent more infectious, which is surprising since these sorts of virus normally stabilise with their hosts, but there you go:

“As Hong Kong reimposes new social distancing restrictions and orders gyms and arcades to close, while asking restaurants to close dine-in service in the evenings, one of its top virus experts is warning the city state might be on the cusp of its biggest and deadliest outbreak yet, and that Hong Kongers must be careful to do their part to help stop SARS-CoV-2 from spreading. Professor Gabriel Leung, dean of the University of Hong Kong’s medical school and a frequently quoted voice whose statements and views help influence the government's response, says he believes there are a least 50 hidden cases in the community, many caused by international travelers according to the SCMP. Moreover, the doctor warned, apparently citing evidence obtained from local researchers, that a new mutation had been discovered in Hong Kong - a mutation that, according to Dr. Leung, has caused the virus to become 30% more infectious. He highlighted Kowloon East and Sha Tin as two areas of heightened risk, and insisted that the city state provide more resources for the elderly there. Like all statements about mutations, this should be taken with a grain of salt, though some research certainly does suggest that minor variations that affect how the virus attaches to the human ACE2 reception could make the virus more infectious. "This is the start of a sustained massive local outbreak the likes of which we have never seen before," Leung said during a radio interview on Sunday. The day before, HK health authorities warned that a third wave of the virus appears to be the most serious by far, as at least 61 people in the city are believed to have been infected, or highly suspected to have been but are awaiting final test results.

Unlike when SARS swept through Hong Kong's financial district in 2003, Hong Kong has been largely spared by COVID-19, with a total of roughly 1,500 cases and only a handful of deaths. Still, officials have remained on guard, and Dr. Leung warned that the location of the latest cases suggests that the city didn't do a good enough job suppressing several known clusters. Saturday’s new local infections arose from restaurants in Ping Shek Estate of Kwun Tong district and in Jordan of Yau Tsim Mong district, along with an old folks’ home in Tsz Wan Shan. "It is very obvious that when the government relaxes social-distancing measures, the pandemic situation gets worse," said Professor Yuen Kwok-yung, a microbiologist at the University of Hong Kong. "There were many restaurants around the elderly care centre in Tsz Wan Shan, including a cha chaan teng frequented by taxi drivers. Many of the reported cases lived in areas of East Kowloon such as San Po Kong, Wong Tai Sin, Kwun Tong, Yau Tong, and Tseung Kwan O," Leung said. During the interview, the doctor urged every Hong Konger to do their part, otherwise the effort will fail. "It is very obvious that when the government relaxes social-distancing measures, the pandemic situation gets worse. The change is immediate," he said. Yuen said Hongkongers needed to be more cautious again and avoid eating out, as the virus could easily transmit from one person to another in enclosed spaces if people did not wear masks.”

     Like everything else associated with this “pandemic,” we need to take it with a semi-trailer load of salt, and see what pans out.
