Viral load could not predict transmissibility of SARS-CoV-2, study finds

The transmission of SARS-CoV-2 virus is dependent on many factors. Although some in vitro studies indicate that the amount of virus isolated from infected individuals affects the successful rate of virus transmission, whether the viral load carried at the individual level can determine transmissibility was unknown.

Obtained SARS-CoV-2 immunity, naturally or via vaccination persists 12 months

In a research paper recently uploaded to the preprint server medRxiv* by Havervall et al. (August 12th, 2021), neutralizing antibody titers towards wild-type SARS-CoV-2 and several variants of concern in individuals having either been vaccinated or infected with mild COVID-19 one year earlier are assessed, finding a reduced neutralization capacity against some strains.

Response to a third SARS-CoV-2 vaccine dose amongst immunocompromised

In a research paper recently uploaded to the preprint server medRxiv* by Schrezenmeier et al. (August 12th, 2021) the potential benefit of three vaccine doses in either a homogenous or heterogeneous dosing regimen amongst kidney transplant patients is assessed, finding that the search for viable vaccination approaches amongst these patients remains an urgent medical need.

Primate study shows benefit of mRNA vaccine booster shot against SARS-CoV-2 variants

In a recent bioRxiv* preprint research paper, a large group of US scientists demonstrate how a booster dose of the mRNA-1273 vaccine can substantially improve both the potency and range of neutralizing antibody responses and mediate protection against upper and lower airway infection by a range of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern – even those relatively resistant to in vitro neutralization.
