Study finds mRNA vaccines induce poor neutralizing antibody response against SARS-CoV-2 variants in dialysis patients

Scientists studied plasma samples from 130 hemodialysis (HD) and 13 peritoneal dialysis patients and showed a poor neutralizing and rapidly decaying antibody response to mRNA vaccines in such individuals.

mRNA-1273 and mRNA-1273.529 Omicron-specific boosters highly effective in mouse model

In a study posted to the bioRxiv* preprint server, a team of researchers from the United States evaluated the protective effect of the preclinical version of the current Moderna Omicron-targeted mRNA-1273.529 vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.529 Omicron infection in mice.

Study looks at potential impact of BBIBPCorV and CoronaVac SARS-CoV-2 vaccines on thyroid

In a recent study posted to Preprints with The Lancet* server, a team of researchers from China performed a serology study of thyroid function and antithyroid antibody levels in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-vaccinated recipients and further evaluated their correlation with SARS-CoV-2 neutralizing antibodies (NAbs) levels.

14 Feb 2022

Study shows IgA antibodies play a significant role in neutralizing SARS-CoV-2

A recent paper by researchers from Australia, currently available on the medRxiv* preprint server, shows how Immunoglobulin A (IgA) antibodies in individuals who were infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) contribute to the neutralization of the virus and its variants, even though this response is heterogeneous and less potent when compared to IgG antibodies.

90 minutes of exercise after vaccination may provide an extra immune boost

Researchers at Iowa State University found 90 minutes of mild- to moderate-intensity exercise directly after a flu or COVID-19 vaccine may provide an extra immune boost.

Performance of SARS-CoV-2 antibodies improves only after previous infection, not vaccination

New research to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) shows that, although over time the number of SARS-CoV-2 antibodies falls in both previously infected and vaccinated patients, the performance of antibodies improves only after previous infection (and not vaccination).
