Scientists from Ludwig-Maximilians-Universitaet (LMU) in Munich, Helmholtz Munich, and Technical University of Munich have shown that the immune system is capable of neutralizing even Omicron after a total of three exposures to the viral spike protein.

Since the beginning of the COVID-19 pandemic, SARS-CoV-2 has continued to evolve, with new variants of concern (VoCs) spreading rapidly.

The clinical and imaging characteristics of COVID-19 breakthrough infections in fully vaccinated patients tend to be milder than those of partially vaccinated or unvaccinated patients, according to a new multicenter study published in the journal Radiology.

The number of confirmed COVID-19 cases worldwide now exceeds 270 million with an overall mortality rate of approximately 2%.

A powerful class of antibiotics called carbapenems can circumvent antibiotic resistance thanks to a particular chain of atoms in their structure. Now, a team of researchers from Penn State and Johns Hopkins University have imaged an enzyme involved in the creation of this chain to better understand how it forms - and perhaps replicate the process to improve future antibiotics. A paper describing the process appears in the journal Nature.

A team co-led by scientists at Scripps Research has found evidence that a compound contained in the medicinal and culinary herb rosemary could be a two-pronged weapon against the SARS-CoV-2 coronavirus that causes COVID-19.

The scientists, in experiments described in a paper published January 6, 2022 in the journal Antioxidants, found that the compound, carnosic acid, can block the interaction between the SARS-CoV-2 outer "spike" protein and the receptor protein, ACE2, which the virus uses to gain entry to cells.

A highly mutated version of SARS-CoV-2, the virus that causes COVID-19, the Omicron variant has been shown to cause breakthrough infections among the vaccinated thanks to its ability to evade the virus-killing neutralizing antibodies that the body makes in response to getting vaccinated.

The Clalit Research Institute, in collaboration with researchers from Harvard University and Tel-Aviv University, analyzed one of the world’s largest integrated health record databases to examine the indirect protection provided to unvaccinated children through parental vaccination with the BNT162b2 (Pfizer) vaccine.

A new study by Yale School of Public Health (YSPH) researchers suggests that the Pfizer-BioNTech vaccine was more than 91% effective at reducing transmission of coronavirus in Israeli households before the emergence of the delta variant. However, the combined effect of the new variant and waning vaccine-induced immunity considerably reduced the vaccine's effectiveness against transmission over time.
