Pfizer-BioNTech’s COVID-19 vaccine effective and safe for use among cancer patients

Researchers in Israel have conducted a study showing that the use of Pfizer-BioNTech’s coronavirus disease 2019 (COVID-19) vaccine appears to be safe and effective among patients with cancer.

Durable antibody response at least 8 months following vaccination with J&J COVID vaccine

A recent study by a team of scientists at Beth Israel Deaconess Medical Center and Janssen Vaccines & Prevention has demonstrated that humoral and cellular immunity elicited by the coronavirus disease 2019 (COVID-19) vaccine Ad26.COV2.S remains active for at least eight months.

Using commensal bacteria to produce vaccine-like immune responses to dangerous bacterium

Researchers have produced vaccine-like immune responses to a dangerous bacterium by colonizing 26 healthy volunteers with a related, but harmless, commensal bacterial species. The first-in-human, controlled infection study showed the strategy was safe, as no side effects were reported and the volunteers didn't transmit the commensal bacteria to bedroom-sharers over the 90-day study.

Striking increase in SARS-CoV-2 antibodies seen with prime dose AstraZeneca vaccine followed by Pfizer-BioNTech

Researchers in Germany have provided evidence that a booster shot of a messenger RNA (mRNA)-based coronavirus disease 2019 (COVID-19) vaccine following prime immunization with AstraZeneca’s adenoviral vector-based vaccine is sufficient to achieve high levels of neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Changes to COVID-19 vaccination strategy could speed up herd immunity

Researchers in the United States have proposed changes to the current coronavirus disease 2019 (COVID-19) vaccination strategy that they say would increase the likelihood of herd immunity being achieved in the most timely and cost-effective manner.

New biological pathway selectively controls how key immune cells mature into functional components

Immunologists at St. Jude Children's Research Hospital have identified a biological pathway that selectively controls how key immune cells, called T follicular helper cells, mature into functional components of the immune system.

New study reports low SARS-CoV-2 breakthrough infections in vaccinated healthcare workers

Researchers examined cases of SARS-CoV-2 infection in fully and partially vaccinated healthcare workers, finding that vaccination provided strong immunity to the virus even though VOCs are on the rise in the non-vaccinated community at large.

Will the US’s COVID-19 vaccination campaign be undermined by novel SARS-CoV-2 variants of concern?

New research from Arizona State University, USA, uses a novel mathematical model to predict the impact of vaccination and vaccine-induced cross-protection on the B.1.1.7 variant and other SARS-CoV-2 variants circulating in the US as of June 2021. The study has been published in medRxiv* preprint server, while it undergoes peer review.

COVID-19 vaccination may be stemming evolution of “fitter” SARS-CoV-2 variants

Researchers in the United States and India have presented the first known evidence that the rollout of coronavirus disease 2019 (COVID-19) vaccination is restricting the evolutionary and immune escape pathways accessible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Moderna’s COVID-19 vaccine elicits durable T cell memory and antibody responses

Researchers in the United States have shown that Moderna’s mRNA-1273 coronavirus disease 2019 (COVID-19) vaccine induces durable antibody and T cell responses to the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are comparable to those seen in cases of COVID-19 caused by natural SARS-CoV-2 infection.

Two chemoattenuated PfSPZ malaria vaccines provide strong and lasting protection

A team of researchers recently optimized regimens for CVac, wherein aseptic, purified, cryopreserved, and infectious PfSPZ were inoculated and mixed with PYR and CQ.

Lack of symptoms following COVID-19 mRNA vaccination doesn't mean vaccine not working

A study conducted by researchers from Maryland in the United States has found no correlation between the symptoms that develop following vaccination against coronavirus disease 2019 (COVID-19) and the antibody responses that are generated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Varenicline blocks SARS-CoV-2 infection in cells and animal models

A new paper released on the bioRxiv* preprint server suggests that the nicotinic acetylcholine receptor (nACHR) agonist, varenicline tartrate, has antiviral activity against the virus.

Novavax COVID-19 vaccine demonstrates ~90% efficacy against SARS-CoV-2

The findings reveal that the two-dose regimen of the vaccine is almost 90% effective against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Moreover, the vaccine shows high efficacy against the B.1.1.7 variant (Alpha) of SARS-CoV-2.

COVAX urges equal recognition of all COVID-19 vaccines

COVAX was built on the principle of equitable access to COVID-19 vaccines to protect the health of people all across the globe. That means protecting their lives and livelihoods, including their ability to travel and conduct trade.

Unprecedented lobbying effort scores big win for California public health

After more than a decade of fruitless entreaties from public health advocates, Democratic lawmakers have secured a landmark agreement that promises $300 million a year in new state funding to fortify and reimagine California's hollowed-out public health system, a complex network of services shouldered largely by the state's 61 local health departments.

Is there a link between circadian rhythms and COVID-19 severity?

This study showed that the time of day of SARS-CoV-2 infection could impact the severity of the viral infection and the host immune response.

Scientists reveal the role of newly introduced lineages in COVID-19 resurgence in Europe

Following the first wave of SARS-CoV-2 infections in spring 2020, Europe experienced a resurgence of the virus starting late summer. Although it appears clear that travel had a significant impact on the circulation of the virus, it remains challenging to assess how it may have restructured and reignited the epidemic in the different European countries.

Antibody development against SARS-CoV-2 following Moderna vaccine

In a paper recently uploaded to the preprint server medRxiv* by Belda et al. (June 27th, 2021) two seroconversion panels containing the sera of individuals that received the Moderna (mRNA-1273) vaccine are compared, and the impact on neutralizing IgG antibody titers in these individuals is analyzed.

Intranasal COVID-19 vaccine developed from bacterial extracellular vesicle induces robust antibody response in preclinical trials

A team of US-based scientists recently developed a novel vaccine candidate against SARS-CoV-2, the causative pathogen of COVID-19. The vaccine is composed of extracellular vesicles of Salmonella typhimurium incorporated with the spike receptor-binding domain (RBD) of SARS-CoV-2. Upon intranasal administration in hamsters, the vaccine induces strong blood antibody titers and protects against severe COVID-19.
