Authors: Beth Daley, Editor and General Manager To get the upper hand on the coronavirus, we first need to understand how our immune system reacts to it. Understanding this will lead to better treatments, effective vaccines and knowing how near we are to herd immunity – and if it’s even achievable. Every day, new research […]

Authors: Pablo F Cañete 1, Carola G Vinuesa 2 Abstract Understanding which arms of the immune response are responsible for protection against SARS-CoV-2 infection is key to predicting long-term immunity and to inform vaccine design. Two studies in this issue of Cell collectively suggest that, although SARS-CoV-2 infection may blunt long-lived antibody responses, immune memory might still be […]
Authors: Sarah C.P. Williams A study of antibody-producing B cells from patients who recovered from COVID-19 reveals a new cross-reactive antibody and what makes some B cells more effective at neutralizing the virus. Inside the body of a person with COVID-19, the immune system’s B cells are engaged in a full-scale battle with the SARS-CoV-2 […]
Authors: Isaak Quast1 and David Tarlinton1,∗ Immunological memory is a mechanism to protect us against reinfection. Antibodies produced by B cells are integral to this defense strategy and underlie virtually all vaccine success. Here, we explain how B cell memory is generated by infection and vaccination, what influences its efficacy and its persistence, and how characterizing these […]
Vaccinated people infected with the Delta variant of the CCP (Chinese Communist Party) virus, which causes COVID-19, may be as infectious as their unvaccinated counterparts, early analysis from Public Health England (PHE) suggests. This coincides with a recent study from the United States, where similar results were observed in Wisconsin. “Some initial findings … indicate that levels […]
KEY POINTS The pandemic is not coming to an end soon — given that only a small proportion of the world’s population has been vaccinated, said Larry Brilliant, a well-known epidemiologist. Brilliant, who was part of the WHO team that helped eradicate smallpox, said the delta variant is “maybe the most contagious virus” ever. The […]
Since late last year, the country has been overrun by a succession of coronavirus variants, each with its own suite of mutations conferring slightly different viral traits. For much of this year, the alpha variant — officially known as B.1.1.7 and first seen in the United Kingdom — looked like the clear winner, accounting for the majority […]
They are just making up narratives now, and the media are not calling them out on it…. The Director of the CDC made an important admission during an interview today on CNN. CDC Director Rochelle Walensky stated the vaccine does not prevent COVID-19 infection, nor does it stop the vaccinated person from transmitting the infection or the […]
Speaking at the Center for Strategic and International Studies on Tuesday, Dr. Anthony Fauci inadvertently hinted at why moving the goalposts on herd immunity is important to the Biden Administration’s strategy for mandating vaccines. Because now once the FDA grants final approval for the jabs (already a foregone conclusion), it will give businesses and colleges […]
