Contrary to myths circulating on social media, COVID-19 vaccines do not cause erectile dysfunction and male infertility. What is true: SARS-CoV-2, the virus that causes COVID-19, poses a risk for both disorders. Until now, little research has been done on how the virus or the vaccines affect the male reproductive system. But recent investigations by physicians and researchers here at the University of Miami have shed new light on these questions.

People who have recovered from COVID-19 tend to score significantly lower on an intelligence test compared to those who have not contracted the virus, ...

A full course of two of the most widely available coronavirus vaccines is about as effective against the more contagious delta variant as it was against a previously dominant version of the virus, according to a study published in the New England Journal of Medicine.

Life expectancy in the United States declined by a year and a half in 2020, according to the Centers for Disease Control and Prevention, which says the coronavirus is largely to blame.

Many factors influence our risk of illness from SARS-CoV-2, the coronavirus responsible for COVID-19. That includes being careful to limit our possible exposures to the virus, as well as whether we have acquired immunity from a vaccine or an earlier infection. But once a person is infected, a host of other biological factors, including age and pre-existing medical conditions, will influence one’s risk of becoming severely ill.

Scientists have harnessed CRISPR gene-editing technology to block the replication of the novel coronavirus in human cells — an approach that could one day serve as a new treatment for COVID-19.

Moderna has given out the first doses of an mRNA-based influenza vaccine to participants in an early-phase clinical trial, the company announced Wednesday. Moderna ultimately plans to test the vaccine on about 180 people in the Phase 1/2 randomized, stratified, observer-blind trial. The trial will look at safety, different doses, and immune responses.

For the first time, researchers have found a way to predict when a pregnant woman will go into labor by analyzing immune and other biological signals in a blood sample, according to a study from the Stanford University School of Medicine.

The COVID vaccines currently being deployed were developed with unprecedented speed, but the mRNA technology at work in some of them is an equally impressive success story. Because any desired mRNA sequence can be synthesized in massive quantities, one of the biggest hurdles in a variety of mRNA therapies is the ability to package those sequences into the lipid nanoparticles that deliver them into cells.

Some Canadians are experiencing more intense reactions after a second dose of a COVID-19 vaccine, and experts say that’s to be expected. The usual side effects people feel after vaccines, including fever, soreness, and headache, can feel stronger following the second dose. That’s been the case for many people around the world.

Preliminary results from a landmark clinical trial suggest that CRISPR–Cas9 gene editing can be deployed directly into the body to treat disease. The study is the first to show that the technique can be safe and effective if the CRISPR–Cas9 components — in this case targeting a protein that is made mainly in the liver — are infused into the bloodstream.

Bouncing ultrasound waves around inside your skull sounds ill-advised, but it might provide a way to boost the effectiveness of other treatments in Alzheimer's patients, according to a recent study published in the journal Alzheimer's Research & Therapy.

Psychedelic drugs creating hopes for breakthroughs in depression, anxiety, pain and addiction are being tested at UAB. The university is one of a handful in the nation conducting trials with psilocybin, the active ingredient in hallucinogenic mushrooms.

The highly contagious Delta variant of the coronavirus is surging through Asia, with record numbers of infections in Australia and South Korea, prompting some countries to tighten curbs and others to step up vaccinations.

In patients with mild cognitive impairment, taking lipophilic statins more than doubles their risk of developing dementia compared to those who do not take statins. According to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting, positron emission tomogra

A wireless pacemaker that can dissolve in the body has been created for patients who need only temporary help to regulate their heartbeat. Since the first pacemaker was implanted in 1958, millions of people have benefited from the devices. According to the national audit for cardiac rhythm management, 32,902 pacemakers were implanted for the first time in the UK in the year 2018-19 alone.

People who have previously been infected with COVID-19 may need only one dose of the two-dose mRNA vaccines to achieve maximum protection against the virus, a new UCLA study suggests. But all vaccinated individuals, whether previously infected or not, will likely require booster shots moving forward because antibodies created through both vaccines and natural infection wane at the same relatively rapid rate, the authors say.

BACK IN 2012, daytime TV celebrity Dr. Oz touted the benefits of a miraculous new weight loss solution: green coffee bean extract. He cited a study he claimed proved it. People, he said, didn’t need to change what they ate or how they exercised. They could simply “do whatever they wanted to do” and in the process lose “a pound per week.”
