Covid19-Sources

How can a field faced with broken public and professional trust mend itself? A small foray into the fatal dangers of closed-mindedness and myopic thinking, and what can be done about it now.

The mRNA coronavirus disease 2019 (COVID-19) vaccines have shown high effectiveness in the prevention of symptomatic COVID-19, hospitalization, severe disease and death. Nevertheless, a minority of vaccinated individuals might become infected and experience significant morbidity. Characteristics of vaccine breakthrough infections have not been studied. We sought to portray the population of Israeli patients, who were hospitalized with COVID-19 despite full vaccination.

Auch im Sommer infizieren sich immer mehr Kinder mit RSV. Die Niederlande verzeichnen derzeit einen starken Anstieg an Infektionen. Muss Deutschland sich jetzt bereit machen?

Während bei den mRNA-Vakzinen von Biontech und Moderna nur Risikogruppen eine Auffrischung empfohlen wird, gilt dies für die Vektor-Impfstoffe von Astrazeneca und Johnson&Johnson grundsätzlich. Warum ist das so? Müssen sich Impflinge Sorgen machen?

The Oxford-AstraZeneca COVID-19 vaccine ChAdOx1 nCoV-19 is associated with a risk for vaccine-induced immune thrombosis with thrombocytopenia syndrome in the range of one to two cases per 100 000 vaccinations, with younger women showing the highest risk.1,2 Additional cases have been reported for the Johnson & Johnson adenoviral vector-based Ad26.CoV2.S COVID-19 vaccine.3 Vaccine-induced antibodies against platelet factor 4 have been implicated in the pathogenesis.1,2 These antibodies might be amplified by booster vaccination with an adenoviral vector, which prompted recommendations to boost with an mRNA-based vaccine instead, although data on safety and efficacy of heterologous prime–boost regimens are sparse.

Although COVID-19 in children is usually of short duration with low symptom burden, some children with COVID-19 experience prolonged illness duration. Reassuringly, symptom burden in these children did not increase with time, and most recovered by day 56. Some children who tested negative for SARS-CoV-2 also had persistent and burdensome illness. A holistic approach for all children with persistent illness during the pandemic is appropriate.

A heroic community effort at a daring hospital saved lives, led to today’s ventilators and revolutionized medicine — it holds lessons for our times.

Eine neue Auswertung von AOK-Daten zeigt, dass in Deutschland wesentlich mehr COVID-Patienten mit ECMO-Beatmung versterben als anderswo. Sind wir schlechter? Oder was ist los?

As eradication of SARS-CoV-2 will be unlikely, we have high confidence in stating that there will always be variants. The number of variants will depend on control measures. We describe hypothetical scenarios by which SARS-CoV-2 could further evolve and acquire, through mutation, phenotypes of concern, which we assess according to possibility. For this purpose, we consider mutations in the ‘body’ of the virus (the viral genes that are expressed in infected cells and control replication and cell response), that might affect virus fitness and disease severity, separately from mutations in the spike glycoprotein that might affect virus transmission and antibody escape. We assess which scenarios are the most likely and what impact they might have and consider how these scenarios might be mitigated. We provide supporting information based on the evolution of SARS-CoV-2, human and animal coronaviruses as well as drawing parallels with other viruses.

SARS-CoV-2 Lambda, a new variant of interest, is now spreading in some South American countries; however, its virological features and evolutionary trait remain unknown. Here we reveal that the spike protein of the Lambda variant is more infectious and it is attributed to the T76I and L452Q mutations. The RSYLTPGD246-253N mutation, a unique 7-amino-acid deletion mutation in the N-terminal domain of the Lambda spike protein, is responsible for evasion from neutralizing antibodies. Since the Lambda variant has dominantly spread according to the increasing frequency of the isolates harboring the RSYLTPGD246-253N mutation, our data suggest that the insertion of the RSYLTPGD246-253N mutation is closely associated with the massive infection spread of the Lambda variant in South America.

Ein Göttinger Forscherteam hat Mini-Antikörper entwickelt, die das Coronavirus SARS-CoV-2 und dessen gefährliche neue Varianten effizient ausschalten. Die sogenannten Nanobodies binden und neutralisieren das Virus bis zu 1000 Mal besser als zuvor entwickelte Mini-Antikörper. Zudem konnten die Wissenschaftler*innen die Mini-Antikörper so weit perfektionieren, dass sie sehr stabil sind und extreme Hitze unbeschadet überstehen. Diese einzigartige Kombination macht sie zu einem vielversprechenden Wirkstoff, um COVID-19 zu behandeln. Da sich Nanobodies kostengünstig und schnell in großen Mengen herstellen lassen, könnten sie sogar den weltweiten Bedarf an COVID-19-Medikamenten decken. Sie werden aktuell für klinische Tests vorbereitet. (The EMBO Journal, 24.

Rather disappointed by the reporting of what is a heavily flawed study in the media to suggest that long COVID is rare in children. There are many issues with this study that I'm sure long COVID researchers & patients will flag, but here's my analysis🧵 https://t.co/IVPGwWBsFr

Our study is the first to demonstrate the presence of the COVID-19 virus in the penis long after the initial infection in humans. Our results also suggest that widespread endothelial cell dysfunction from COVID-19 infection can contribute to ED. Future studies will evaluate novel molecular mechanism …

Objectives Highly effective vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed but variants of concerns (VOCs) with mutations in the spike protein are worrisome, especially B.1.617.2 (Delta) which has rapidly spread across the world. We aim to study if vaccination alters virological and serological kinetics in breakthrough infections. Methods We conducted a multi-centre retrospective cohort study of patients in Singapore who had received a licensed mRNA vaccine and been admitted to hospital with B.1.617.2 SARS-CoV-2 infection. We compared the clinical features, virological and serological kinetics (anti-nucleocapsid, anti-spike and surrogate virus neutralization titres) between fully vaccinated and unvaccinated individuals. Results Of 218 individuals with B.1.617.2 infection, 84 had received a mRNA vaccine of which 71 were fully vaccinated, 130 were unvaccinated and 4 received a non-mRNA. Despite significantly older age in the vaccine breakthrough group, the odds of severe COVID-19 requiring oxygen supplementation was significantly lower following vaccination (adjusted odds ratio 0.07 95%CI: 0.015-0.335, p=0.001). PCR cycle threshold (Ct) values were similar between both vaccinated and unvaccinated groups at diagnosis, but viral loads decreased faster in vaccinated individuals. Early, robust boosting of anti-spike protein antibodies was observed in vaccinated patients, however, these titers were significantly lower against B.1.617.2 as compared with the wildtype vaccine strain. Conclusion The mRNA vaccines are highly effective at preventing symptomatic and severe COVID-19 associated with B.1.617.2 infection. Vaccination is associated with faster decline in viral RNA load and a robust serological response. Vaccination remains a key strategy for control of COVID-19 pandemic. ### Competing Interest Statement BEY reports personal fees from Roche and Sanofi, outside the submitted work.

Assuming further that 30 and 50% of individuals were immune to Spanish influenza after the wave in April 1918 and the first subsequent wave, respectively, these findings imply that, in a totally susceptible population, an infectious case could have led to 2.4-4.3 and 2.6-10.6 cases in community-base …
