Thinking impaired in 60% of COVID-19 survivors

In a sample of over 400 older adults in Argentina who had recovered from COVID-19, more than 60% displayed some degree of cognitive impairment, a researcher from The University of Texas Health Science Center at San Antonio reported July 29 at the Alzheimer’s Association International Conference.

Advantages of intranasal vaccination against SARS-CoV-2

There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, University of Alabama at Birmingham immunologists Fran Lund, Ph.D., and Troy Randall, Ph.D., write in a viewpoint article in the journal Science.

Antibiotics may help to treat melanoma

Some antibiotics appear to be effective against a form of skin cancer known as melanoma. Researchers at KU Leuven, Belgium, examined the effect of these antibiotics on patient-derived tumours in mice. Their findings were published in the Journal of Experimental Medicine.

Take your best shot: Which SARS-CoV-2 vaccine should I get, if any?

Vaccine hesitancy continues to be a hurdle in the development of widespread immunity within the U.S. population as the COVID-19 pandemic enters its second year.

Researchers at the University of Cincinnati College of Medicine have developed a computerized decision analytic model to compare projected outcomes of three vaccine strategies:

Study shows why second dose of COVID-19 vaccine shouldn't be skipped

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.

The finding strongly supports the view that the second shot should not be skipped.

Are silver nanoparticles a silver bullet against microbes?

Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They can be in the form of antibiotics, used to treat bodily infections, or as an additive or coating on commercial products used to keep germs at bay. These life-saving tools are essential to preventing and treating infections in humans, animals and plants, but they also pose a global threat to public health when microorganisms develop resistance to them, a concept known as antimicrobial resistance.

One shot of the Sputnik V vaccine triggers strong antibody responses

A single dose of the Sputnik V vaccine may elicit significant antibody responses against SARS-CoV-2, finds a study published July 13 in the journal Cell Reports Medicine.

"Due to limited vaccine supply and uneven vaccine distribution in many regions of the world, health authorities urgently need data on the immune response to vaccines to optimize vaccination strategies," says senior author Andrea Gamarnik of the Fundación Instituto Leloir-CONICET in Buenos Aires, Argentina.
