News from U.S. manufacturer Moderna that its COVID-19 vaccine is still “expected to be protective” against a virus variant first detected in South Africa came as a relief to scientists and the public. But the 25 January announcement included a caveat: Antibodies triggered by the vaccine appear to be a little less potent against the new variant, named B.1.351, than the one the vaccine was developed for. So researchers were perhaps even more relieved to hear the company will start developme...

BackgroundTo mitigate the effects of COVID-19, a vaccine is urgently needed. BBV152 is a whole-virion inactivated SARS-CoV-2 vaccine formulated with a toll-like receptor 7/8 agonist molecule adsorbed to alum (Algel-IMDG) or alum (Algel).MethodsWe did a double-blind, multicentre, randomised, controlled phase 1 trial to assess the safety and immunogenicity of BBV152 at 11 hospitals across India. Healthy adults aged 18–55 years who were deemed healthy by the investigator were eligible. Individua...

BackgroundPatients with COVID-19 pneumonia have an excess of inflammation and increased concentrations of cytokines including interleukin-1 (IL-1). We aimed to determine whether anakinra, a recombinant human IL-1 receptor antagonist, could improve outcomes in patients in hospital with mild-to-moderate COVID-19 pneumonia.MethodsIn this multicentre, open-label, Bayesian randomised clinical trial (CORIMUNO-ANA-1), nested within the CORIMUNO-19 cohort, we recruited patients from 16 University hos...

Johnson & Johnson Announces Single-Shot Janssen COVID-19 Vaccine Candidate Met Primary Endpoints in Interim Analysis of its Phase 3 ENSEMBLE Trial

• Vaccine Candidate 72% Effective in the US and 66% Effective Overall at Preventing Moderate to Severe COVID-19, 28 Days after Vaccination• 85% Effective Overall in Preventing Severe Disease and Demonstrated Complete Protection Against COVID-19 related Hospitalization and Death as of Day 28• Protection Against Severe Disease Acro...

NIAID’s Rocky Mountain Laboratories (RML) in Hamilton, Montana, produced images of the novel coronavirus (SARS-CoV-2, previously known as 2019-nCoV) on its scanning and transmission electron microscopes on Tuesday, Feb. 11, 2020. SARS-CoV-2 causes COVID-19 disease, which has grown to be a global public health emergency since cases were first detected in Wuhan, China, in December 2019. RML investigator Emmie de Wit, Ph.D., provided the virus samples as part of her studies, microscopist...

Johnson & Johnson (NYSE: JNJ) (the Company) today announced the European Commission (EC), acting on behalf of the European Union (EU) Member States, has approved an Advance Purchase Agreement in which the Janssen Pharmaceutical Companies will supply 200 million doses of its COVID-19 vaccine candidate to EU Member States following approval or authorization from regulators. The EU Member States also have the option to secure up to 200 million additional doses.

“The COVID-19 pande...

Johnson & Johnson could deliver the first doses of its COVID-19 vaccine to Europe in April, an EU official told Reuters on Wednesday after a top lawmaker said the U.S. healthcare company was likely to seek EU regulatory approval in February.
Clinical data on the vaccine has been assessed by the European Medicines Agency (EMA) since Dec. 1 under a rolling review to speed up possible approval.

A senior EU official, who is involved in negotiations with vaccine makers and spoke on c...

Abstract
We are currently faced with the question of how the CoV-2 severity may change in the years ahead. Our analysis of immunological and epidemiological data on endemic human coronaviruses (HCoVs) shows that infection-blocking immunity wanes rapidly, but disease-reducing immunity is long-lived. Our model, incorporating these components of immunity, recapitulates both the current severity of CoV-2 and the benign nature of HCoVs, suggesting that once the endemic phase is reached and prim...

Vaccines typically require years of research and testing before reaching the clinic, but in 2020, scientists embarked on a race to produce safe and effective coronavirus vaccines in record time. Researchers are currently testing 68 vaccines in clinical trials on humans, and 20 have reached the final stages of testing. At least 90 preclinical vaccines are under active investigation in animals.

The UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) has revised its guidance so that pregnant and breastfeeding women can receive the covid-19 vaccine.

Writing in BMJ Opinion, Helen Hare, an acute medicine trainee, and Kate Womersley, an academic foundation trainee, said that the change had come after strong pressure from campaigners, clinicians, and some of the women affected.1

The MHRA had previously recommended that breastfeeding women should not be given ...

For most of November, 2020, England was in lockdown to force down the incidence of COVID-19 cases that had steadily increased in the late summer and autumn. Other countries in the UK (Wales, Scotland, and Northern Ireland) had also been reimposing and subsequently lifting restrictions, since each of the four nations is in charge of its own COVID-19 control plans.For a while, the strategy in England appeared to have worked, with many areas that previously had high case incidence seeing rates d...

Abstract The SARS-CoV-2 lineage B.1.1.7, now designated Variant of Concern 202012/01 (VOC) by Public Health England, originated in the UK in late Summer to early Autumn 2020. We examine epidemiological evidence for this VOC having a transmission advantage from several perspectives. First, whole genome sequence data collected from community-based diagnostic testing provides an indication of changing prevalence of different genetic variants through time. Phylodynamic modelling additionally...
