The Omicron variant of SARS-CoV-2 has spread across the world like wildfire. But the mutant Covid-19 virus, although highly transmissible, has not brought with it the high death counts of previous waves, such as the Delta variant.
Instead, the effects of Omicron have been described as “generally mild,” and comparable to the Common Cold. Even an initial reported single case of a Texas man having died from the Omicron variant has been thrown into question.
One of the mysteries of the Omicron variant is why the reaction appears to be so consistently mild, regardless of vaccination status. There has been a lot of questioning about whether prior infection to Delta and wild variants has provided some antibody response to Omicron, which can cause infections even in those who have been vaccinated and “boosted.”
The Africa Health Research Institute has undertaken an innovative study to look into whether there is any transferrability of natural immunity between the Omicron and Delta variants. The lead author in the pre-print study submitted for publication, Alex Sigal, spearheaded a team of over thirty researchers revealed the promising preliminary results.
“We have submitted new results to medRxiv: Omicron infection enhances neutralizing immunity against the Delta variant,” Sigal announced on Twitter.
We studied people who were infected with Omicron close to when they had symptoms and about 2 weeks later:
“The increase neutralizing immunity against Omicron was expected – that is the virus these individuals were infected with,” Sigal noted. “However, we also saw that the same people – especially those who were vaccinated – developed enhanced immunity to the Delta variant. If, as it currently looks like from the South African experience, Omicron is less pathogenic, then this will help push Delta out, as it should decrease the likelihood that someone infected with Omicron will get re-infected with Delta.”
This may be the proverbial “dead end” for Covid that was once promised. However, unlike the ‘vaccines’ touted by the likes of Dr. Anthony Fauci, nature will put an end to the Covid pandemic. Just like all other pandemics in human history.
“If that’s true, then the disruption Covid-19 has caused in our lives may become less,” Sigal continued, before listing the collaborators in the study. The study itself is worth a closer look.
The study “Omicron infection enhances neutralizing immunity against the Delta variant” provides an overview of the Covid pandemic before delving into the results.
“Omicron has been shown to be highly transmissible and have extensive evasion of neutralizing antibody immunity elicited by vaccination and previous SARS-CoV-2 infection,” the authors state. “Omicron infections are rapidly expanding worldwide often in the face of high levels of Delta infections. Here we characterized developing immunity to Omicron and investigated whether neutralizing immunity elicited by Omicron also enhances neutralizing immunity of the Delta variant. We enrolled both
33 previously vaccinated and unvaccinated individuals who were infected with SARS-CoV-2 in the Omicron infection wave in South Africa soon after symptom onset.”
“We then measured their ability to neutralize both Omicron and Delta virus at enrollment versus a median of 14 days after enrollment,” the authors continue. “Neutralization of Omicron increased 14-fold over this time, showing a developing antibody response to the variant. Importantly, there was an enhancement of Delta virus neutralization, which increased 4.4-fold. The increase in Delta variant neutralization in individuals infected with Omicron may result in decreased ability of Delta to re-infect those individuals. Along with emerging data indicating that Omicron, at this time in the pandemic, is less pathogenic than Delta, such an outcome may have positive implications in terms of decreasing the Covid-19 burden of severe disease.”
Wow. This would be a relief for those who have mused that Omicron may push out Delta and leave us in an enhanced situation of increasing Natural Immunity to Covid-19. The United States is already at approximately 200 million people with natural immunity, which was once argued by the Mayo Clinic to be sufficient to claim “herd immunity.” However, the variants have clouded the picture of what that target might actually be.
The preliminary new research out of Africa shows that the transfer in natural immunity between variants is very strong, thus hinting that the Covid pandemic as we know it is effectively ‘over.’
