Third dose of mRNA-based COVID-19 vaccine efficiently recalls Omicron-reactive B cell memory

A new study examined how the quantity and quality of antibody and memory B cell responses to SARS-CoV-2 change temporally and with the number of exposures to antigens.

Why pregnant people were left behind while vaccines moved at ‘warp speed’ to help the masses

Kia Slade was seven months pregnant, unvaccinated, and fighting for breath, her oxygen levels plummeting, when her son came into the world last May.

Study reveals sex-dimorphic immune imprints and in vivo functional impacts of mild COVID-19

Researchers used a systems immunology approach to analyze the immune states of healthy and non-obese subjects who recovered from mild COVID-19 and compared them with age- and sex-matched COVID-19-naive controls.

Immunological landscape of England during Omicron-driven SARS-CoV-2 wave

In a new study, researchers determined the immunological landscape of England throughout the SARS-CoV-2 Omicron wave.

Edible egg-derived IgY antibodies against SARS-CoV-2 Omicron

A new study posted to the bioRxiv* preprint server reports on the development of anti-RBD immunoglobulin Y (IgY) antibodies from chicken eggs to block the binding of the viral RBD to human ACE2 receptors. This approach has several advantages since chicken egg-derived IgY can be edible and polyclonal can target multiple epitopes, enhancing neutralizing activity.

Study on Omicron related mortality in cancer patients during recent COVID wave

A recent pre-proof study published in the journal Cancer Cell assessed the CFR of cancer patients during the third wave of the coronavirus disease 2019 (COVID-19) pandemic caused by the SARS-CoV-2 Omicron variant.

Genetics may influence how the body responds to vaccines and boosters

Genetics play an important role in how our bodies respond to vaccines and booster shots, suggesting that certain protective responses elicited by vaccination could be more effective with personalization, according to a new study led by University of Michigan researchers.

Study explores the effectiveness of Moderna COVID-19 vaccine against omicron, delta variants

New Kaiser Permanente research published February 21, 2022 in Nature Medicine shows that while Moderna COVID-19 vaccine protection is strong against coronavirus infection by the delta variant, it is not as strong against infection from the omicron variant.

Understanding the immune responses after secondary vaccinations with Pfizer and Moderna vaccines

In a new study, researchers assessed the serological responses to secondary booster doses of Pfizer's Comirnaty and Moderna's Spikevax COVID-19 vaccines.

Study shows BCG vaccine provides no protection against SARS-CoV-2 in mice and hamsters

Researchers investigated the effectiveness of the BCG vaccines against SARS-CoV-2 infections using three animal models.

SARS-Cov-2 reinfection in Syrian hamsters does not result in disease

Researchers have been investigating the reinfection of different SARS-CoV-2 variants in Syrian hamsters and found that this does not seem to result in disease or any significant pulmonary pathology.

More evidence vaccines prevent ICU admission and mortality from SARS-CoV-2

In a recent study posted to the medRxiv* preprint server, researchers estimated the comparative virulence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between the vaccinated and unvaccinated subjects hospitalized with coronavirus disease 2019 (COVID-19) in Canada.

SARS-CoV 2 Omicron prevalent in vaccine breakthrough cases in Bahia, Brazil

In a recent study posted to the medRxiv* pre-print server, researchers performed genomic monitoring to estimate the magnitude and range of the different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) in SARS-CoV-2 reinfection cases among fully vaccinated individuals in Salvador, Bahia, Brazil.

Low risk of second allergic reaction after SARS-CoV-2 vaccination

In a recent investigation posted to the journal JAMA Internal Medicine,* researchers estimate the risk of a repeated allergic reaction to the second severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger ribonucleic acid (mRNA) vaccine dose in those with a history of allergic responses following the first dose by conducting a systematic review and meta-analysis.

Omicron neutralizing titers after third BNT162b2 dose are persistent

The new study, published in the journal Cell Host and Microbe, also finds that the neutralization against Omicron remains robust at four months after the third dose of the BNT162b2 vaccine.

Study shows Pfizer-BioNTech booster protects over 65s against Delta and Omicron

New research in nursing home residents found that a third dose of the Pfizer-BioNTech COVID-19 vaccine was effective for at least three months in protecting against the Delta and Omicron variant. While two doses of an mRNA COVID-19 vaccine showed poor neutralization to Omicron than Delta, a booster shot increased neutralizing antibody responses.
