Potential variant of interest in South Africa assigned to the PANGO lineage C.1.2

Continual genomic surveillance of the SARS-CoV-2 strains in South Africa has revealed an increase in the number of sequences belonging to C.1 lineage during the third wave (May 2021) of SARS-CoV-2 infections. This observation was unexpected because C.1 was last reported in January 2021.

Scientists assess SARS-CoV-2 mutants in ferret hosts

In a paper recently uploaded to the preprint server bioRxiv* by the cause of SARS-CoV-2 mutations observed in mink and ferrets is investigated, and the danger posed by such mutations to humans assessed.

Analysis of antibody titer decay following vaccination or SARS-CoV-2 infection

A new study focused on the decrease in antibody titers following two doses of BNT162b2 vaccine or SARS-CoV-2 natural infection in Israel.

Research highlights the potential benefits of SARS-CoV-2 S gene mutants as immunogens

Previous research has shown that the spike (S) protein of -CoV-2 binds to a host cell receptor, facilitating viral entry.

Scientists forecast healthcare burden of future COVID waves

The findings indicate that given the lower vaccine efficacy against the SARS-CoV-2 delta variant, France may face a large epidemic wave infecting 25% of the general population even with a 95% vaccine coverage. This, in turn, could affect the healthcare system in terms of hospital bed occupancy. The study is currently available on the medRxiv* preprint server.

SARS-CoV-2 Delta likely to acquire resistance to wild-type spike vaccines

A new study published on the preprint server bioRxiv* explores the mechanism of the Delta variant's high infectivity and suggests a plausible pathway by which the Delta variant could escape from vaccine-induced immunity.

Breast milk of vaccinated mothers contains antibodies that may protect nursing infants from COVID-19

The breast milk of lactating mothers vaccinated against COVID-19 contains a significant supply of antibodies that may help protect nursing infants from the illness, according to new research from the University of Florida.

New clinical trial to test third dose of COVID-19 vaccine for immunocompromised people

A new clinical trial to determine whether a third dose of vaccine will improve the immune response for people who have weakened immune systems is launching in the UK.

SARS-CoV-2 Delta variant associated with more breakthrough infections

The study highlights that compared to the previously circulating alpha variant, the delta variant is associated with higher infectious virus load and a lower level of humoral immunity in the upper respiratory tract. The study is currently available on the medRxiv* preprint server prior to peer review.

Researchers discover molecule that plays an important role in sperm motility regulation

About 120 million unintended pregnancies occurred each year between 2015 and 2019 worldwide. While there are oral contraceptives for women, the development of oral contraceptives for men has not been successful.

Frameshift deletion mutation in ORF7a may provide fitness advantage to Australia's SARS-CoV-2 delta variants

A team of scientists from Australia has recently identified a frameshift deletion mutation in ORF7a of the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The mutation results in the production of a truncated peptide with altered functionality. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Patients on dialysis show reduced antibody levels four months after COVID-19 vaccination

A new longitudinal study posted to the medRxiv* preprint server suggests vaccinated patients on chronic hemodialysis having waning immunity against severe acute respiratory syndrome 2 (SARS-CoV-2) variants of concern. The German researchers found a drop in neutralizing antibody levels and T cell activity four months after receiving their second Pfizer-BioNTech vaccine.

FDA approves COVID-19 mRNA vaccine that uses fundamental Penn technology

The U.S. Food and Drug Administration has given the first full approval to a COVID-19 mRNA vaccine, which uses modified mRNA technology invented and developed by scientists in the Perelman School of Medicine at the University of Pennsylvania, whose years of research in mRNA science laid a critical piece of the foundation for the largest global vaccination campaign in history.

Expansion of seasonal betacoronavirus antibodies post-vaccination is associated with reduction in neutralization of the SARS-CoV-2 variants of concern

A new study determined the antibody response to SARS-CoV-2 and seasonal viruses induced by BNT162b2-Comirnaty vaccination in healthcare workers.

New study reveals unique immune responses to SARS-CoV-2, Ebola and respiratory syncytial virus using B cell repertoire analysis

A new study has been published on the bioRxiv* preprint server, which takes a long-read repertoire amplification approach to better understand, compare and contrast B cell responses to emerging or endemic viruses.

UK Health Security Agency launches antibody surveillance program for the general public

Thousands of adults a day will be given free access to antibody tests through a new national surveillance programme launched by the UK Health Security Agency next week, to help improve our understanding of immunity against COVID-19 from vaccination and infection.
