How a user remembers the COVID-19 pandemic is affected by motivators, adding how they feel about their vaccination status. Memories of other vaccinated and unvaccinated people are skewed in opposite directions, leading to other retrospective narratives about the pandemic. These distorted memories influence Americans’ comparison beyond political action and will complicate preparedness for long-term crises.
Many human diseases lack accurate mouse models because it is technically complicated to create genetically humanized mice in large part. A strategy that allows giant swaths of DNA to be rewritten in mouse embryonic stem cells can be used to produce advanced animal models.
Molnupiravir, an antiviral drug used to treat COVID-19, induces many mutations in the SARS-CoV-2 genome that can increase the speed at which the virus evolves, generating viral variants that can simply be transmitted.
Here, the authors expand a vaccine against mucosal SARS-CoV-2 and show immunogenicity and coverage in mice, as well as reduced transmission of the virus in hamsters. This protein vaccine is composed of a stabilized spike protein fused to a monomeric IgG Fc. sell its shipment across epithelial barriers by binding to the neonatal Fc receptor.
Here, the authors administer aerosolized human monoclonal antibodies against SARS-CoV-2-infected rhesus macaques and show that the remedy particularly reduces viral RNA and infectious virus in the respiratory tract, limits lung pathology, and decreases inflammatory cytokines.
Huot et al. show that interferon-γ (IFN-γ) regulates severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patience in bronchoalveolar macrophages of cynomolgus macaques up to 18 months after infection.
Evidence from the trials suggests that SARS-CoV-2 binding antibody thresholds would possibly serve as surrogate markers of neutralizing capacity, although it is not yet known whether this is accurate in the context of variants of concern or in cases of prior infection or vaccination. The authors explore the functionality of the IgG thresholds of the receptor-binding domain to wait for a point of neutralizing capacity that has demonstrated coverage against infection in vaccine trials.
Estimates of SARS-CoV-2-associated mortality in sub-Saharan Africa are dubious due to the lack of comprehensive surveillance formulas. Here, the authors analyze data from a detailed surveillance formula in Kilifi, Kenya, and locate that excess mortality rates were low. with the exception of the elderly.
This study evaluates the efficacy of a second mRNA booster vaccine against COVID-19 against severe disease data from Chile. The authors find that the efficacy of the second mRNA booster shot was superior to that of a variety of other baseline vaccination regimens, but declined over time.

An excessive “mycobiota” in the gut could be involved in triggering destructive immune responses.
SARS-CoV-2 infects macrophages, specifically lipid-laden foam cells, in coronary atherosclerotic plaques in COVID-19 patients; This infection triggers a strong proatherogenic inflammatory response, which may contribute to ischemic cardiovascular headaches in those patients.
Investing $1 billion every year for the next ten years in long-term COVID studies can save the lives of millions of people and save trillions in economic costs.
