Antibody levels remain high nine months after SARS-CoV-2 infection, study shows

Testing of an entire Italian town shows antibody levels remain high nine months after SARS-CoV-2 infection, whether symptomatic or asymptomatic.

Study: Second dose of COVID-19 vaccine induces a powerful boost to the immune system

The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study led by investigators at the Stanford University School of Medicine.

Study suggests children develop short-term humoral immunity following SARS-CoV-2 infection

A single-center, cross-sectional epidemiological survey conducted in Israel has recently pointed out that antibodies induced by natural SARS-CoV-2 infection in children start declining just after 4 months of acute infection. However, their seropositivity rates are not impacted by school reopening. The study has recently been published in the journal Acta Paediatrica.

Grab your mask and notepad, we’re headed back to California’s state Capitol

The best part about returning to the pandemic-besieged state Capitol is that the elected officials are so unused to seeing us reporters after more than a year that some are occasionally extra chatty. The bad part is that the masks make it harder to eavesdrop on the rest of them.

Do mRNA-based COVID-19 vaccines induce memory T cell response similar to natural infection?

A team of scientists from the United States has recently compared the epitope-specific T cell response after natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or vaccination in both naïve and previously infected individuals.

Stronger and longer SARS-CoV-2 RBD-ACE2 binding associated with glycans in new study

A new study has been published on the bioRxiv* preprint server, which focuses on the mechanism behind the binding of SARS-CoV-2 with the host receptor, using a molecular dynamics approach. The authors of this study aim to highlight the role of glycans in initiating the interaction between S and ACE2.

Patient's case report reveals link between Bell’s palsy and Pfizer-BioNTech vaccine

The case of a patient who experienced two facial palsies – one after the first and another after the second dose of the Pfizer-BioNTech COVID-19 vaccine – strongly suggests that Bell’s palsy (facial nerve palsy of unknown cause) is linked to the Pfizer-BioNTech vaccine, doctors write in the journal BMJ Case Reports.

Plant-based vaccines for COVID-19 and other viruses

A review published in the journal Vaccines, explored the history and current status of plant-produced vaccine candidates against enveloped viruses, focusing on virus-like particles (VLPs), which mimic authentic viral structures without containing infectious genetic material.

SARS-CoV-2 B.1.617 mutations L452 and E484Q do not work together to evade antibodies

A short report recently published in the Journal of Infectious Diseases demonstrates how spike mutations L452R and E484Q found in the variant B.1.617.1 of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) each confer modestly diminished sensitivity to Pfizer-BioNTech (BNT162b2) mRNA vaccine-elicited antibodies – with combined mutations having a similar impact as either one of them alone.

Pfizer-BioNTech and Moderna COVID-19 vaccines establish recall responses to reinfection

Researchers in the United States have conducted a study showing that the coronavirus disease 2019 (COVID-19) vaccines developed by Pfizer-BioNTech and Moderna generate a coordinated adaptive immune response that is capable of eliciting recall responses to future infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

How do immunocompromised patients respond to COVID-19 vaccines?

The COVID-19 vaccines produce a boost in antibody activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, new research suggests vaccine responses aren’t all created equal. Their findings showed that immunocompromised patients, such as transplant recipients, with no prior exposure to SARS-CoV-2 produce little to no neutralizing antibodies.

Evaluation of a synthetic DNA SARS-CoV-2 vaccine INO-4800 using a nonhuman primate model

A new study published in Vaccine assesses the safety and efficacy of the synthetic DNA vaccine candidate INO-4800, delivered as a single or double dose regime.

A drug candidate to prevent adverse reactions due to COVID-19 infection or vaccines

A new study describes the promising results of a new drug candidate in combating the illness caused by the binding of COVID-19-specific antibodies to infected cells.

Researchers isolate human monoclonal antibodies that may neutralize several norovirus variants

Researchers at Vanderbilt University Medical Center and the Baylor College of Medicine in Houston, Texas, have taken a big step toward developing targeted treatments and vaccines against a family of viruses that attacks the gastrointestinal tract.

Study provides insights into vaccine acceptance and hesitancy in low- and-middle income countries

New research published in Nature Medicine reveals willingness to get a COVID-19 vaccine was considerably higher in developing countries (80% of respondents) than in the United States (65%) and Russia (30%).

Messenger RNA vaccines against COVID-19 not found in breast milk

Messenger RNA vaccines against COVID-19 were not detected in human milk, according to a small study by UC San Francisco, providing early evidence that the vaccine mRNA is not transferred to the infant.

India's Mission Indradhanush improves vaccination outcomes for children

Researchers at CDDEP recently published 'Improving vaccination coverage and timeliness through periodic intensification of routine immunization: evidence from Mission Indradhanush' where they evaluated the performance of India's Mission Indradhanush (MI) child vaccination campaign -- a periodic intensification of the routine immunization program.

Moderna SARS-CoV-2 vaccine highly effective against alpha and beta variants

The Moderna SARS-CoV-2 vaccine was widely distributed and had a reported efficacy in clinical trials of 94.1% against the wildtype SARS-CoV-2 following the second dose administration. Therefore, Chemaitelly et al. used this as an opportunity to measure the vaccine's efficacy against these variants as reported in a recent Nature Medicine paper, finding that the vaccine has good efficacy in all aspects.

Mixing COVID vaccines generates a comparable immune response

The validity and safety of mixing first and second doses of different types are explored in a paper recently uploaded to the preprint server medRxiv* by Rose et al. (July 13th, 2021), finding that robust antibody response is induced, comparable to, and perhaps even exceed that generated by homologous dosing.

Water-soluble vitamin E compounds directly inhibit SARS-CoV-2 replication and synergize with remdesivir

Researchers in the United States have shown that water-soluble derivatives of vitamin E (α-tocopherol) exhibit potent antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).
