Dan Rodricks: I recently had conversations with a middle-aged man who is extremely careful about what he puts into his body. He eats lots of fruits and vegetables and stays away from red meat and processed foods. He also refuses to get the vaccine against COVID-19, even as infections are on the rise again.

Since early on, the pandemic has highlighted inequality both on a micro scale—within countries, between social classes and ethnic groups—and a macro one—between rich and poor countries. It also confirmed what many of those working in global health—particularly in and for low- and middle-income countries—expected: In an emergency, no matter the declared values and intention, people will first and foremost, and in many cases only, care about themselves and their own.

HIV-1 can be transmitted through vaginal, anal, and oral sex, whether it’s with a same-sex or different-sex partner. But the risk of developing it seems to vary depending on how the disease is transmitted. In fact, the HIV virus may be more virulent when passed between male and female partners who have penile-vaginal sex than among men who have anal sex with other men, according to a new study from the Indian Institute of Science.

Americans, by and large, are putting the pandemic behind them. Now that Omicron is in the rearview mirror and cases are plummeting, even many of those who have stayed cautious for two full years are spouting narratives about “going back to normal” and “living with COVID-19.” But in the global South, COVID-19 is much harder to ignore. More than a year after the start of the mass-vaccination campaign, nearly 3 billion people are still waiting for their first shot.

Over two years since the first cases started appearing in Wuhan, China, there is much we don’t know about the origins of SARS-CoV-2, the virus causing COVID-19. But a quick resolution to that question is possible: scientists could find bats in a cave somewhere in China or in southeast Asia and trace a chain leading from those bats to the COVID-19 outbreak in Wuhan. Realistically, however, recent history offers little promise for this to happen quickly.

Could a “broad spectrum” booster increase our immunity to many pathogens simultaneously? The first tuberculosis vaccine was developed in 1921, by two French scientists, Albert Calmette and Camille Guérin. It was called Bacillus Calmette-Guérin, or B.C.G., and has long been one of the world’s most widely administered shots. From the beginning, its power was surprising. B.C.G. contains a bacterium similar to the one that causes TB, and engenders an immune defense specific to that disease. But, as Calmette noted in a paper in 1931, those vaccinated with B.C.G. at birth were around seventy-five per cent less likely to die in their early years of any cause.

Weather Channel: Mystery Thickens Over COVID-19's Origin; Claims of Hidden Early Genetic Information Attracts Further Scrutiny
COVID-19 pandemic has been wreaking worldwide havoc for nearly 20 months now. Yet, Its origin and early spread continue to be one of the most intriguing scientific puzzles of recent history. Claims that the earliest coronavirus strains leaked out from a lab in the Wuhan Institute of Virology in China have resurfaced and subsided multiple times, throughout the course of the pandemic. While many such claims were eventually disregarded as unfounded speculations of conspiracy theorists, allegations have continued against the Wuhan lab having known about the infection and its subsequent threat, much before the world at large was aware.
Tuesday, June 22, 2021
The Wuhan lab has drawn global scrutiny because of its research on bat coronaviruses in the city where the pandemic began. The events have shined a light on a research niche that — in China, the United States and elsewhere — operates with heightened secrecy because of the national security risks of handling deadly pathogens.
Monday, June 21, 2021
A third wave of coronavirus infections is likely to hit India by October, and although it will be better controlled than the latest outbreak the pandemic will remain a public health threat for at least another year, according to a Reuters poll of medical experts.

What has COVID-19 taught us about preparing for future epidemics? Can we trigger innate immune responses – our first lines of defense - to mitigate novel infections? Can we use live-attenuated vaccines (LAV) meant for other infections to protect us while we develop specific vaccines for new pathogens? On this episode, we talk to virologists Konstantin Chumakov and Robert Gallo about their recent paper entitled “Old vaccines for new infections”.
Thursday, June 03, 2021
More than a year into the COVID-19 pandemic, scientists still aren’t sure where exactly the virus that caused this mess came from, and how it was able to spread so rapidly among humans. With the origins of the coronavirus still up in the air, there’s been a lot of talk of the so-called lab leak theory—the idea that the virus spread to people in a laboratory accident, rather than jumping from a wild animal to a human. In recent days, there’s been a flurry of speculation, and it can be hard to parse what the lab leak theory is all about, how likely it is, and why it matters at all. Here’s our attempt to sort some of that out.

The Baltimore Sun: Maryland sees little flu this season as researchers wonder if flu vaccine staves off COVID-19
February is typically the cruelest month for the flu with thousands of infections, hundreds hospitalized and some dying in Maryland. Not this year. Due in part to the coronavirus pandemic and preventative measures associated with it, the influenza virus is downright rare in Maryland and across the nation. But researchers are wondering if there’s a chance that the flu shot you got in the fall may yet fend off a nasty infection — of COVID-19.

Business Insider: People who had COVID-19 may develop 10 times more antibodies after a single vaccine dose - a sign they might only need one shot
Business Insider - People who had COVID-19 developed at least 10 times more antibodies after their first vaccine dose than the average uninfected person who received two doses, new research shows. Another preliminary study similarly found that healthcare workers who had COVID-19 responded to their first shot the way most people respond to their second. The researchers both suggested that post-COVID patients may only need one shot to sufficiently protect them from the disease again.

A safe, effective vaccine against Covid-19 could resurrect jobs, send kids back to classrooms--change our lives. But how safe and effective? And how quickly can we have it? Dr. Robert Gallo, the AIDS-research pioneer now leading virus science at the Institute of Human Virology at the University of Maryland School of Medicine and the Global Virus Network, argues we could get much of the benefit by inoculating people with an old, very cheap drug -- the oral Polio vaccine developed seven decades ago. Gallo contends it would trigger our ‘innate immunity’-- the body’s emergency response when a threat shows up.

Institute of Human Virology and Italian Researchers identify a SARS-CoV-2 Viral Strain with Deletion in a Protein, Possibly Reducing Fatalities
The Institute of Human Virology (IHV) at the University of Maryland School of Medicine, a Global Virus Network (GVN) Center of Excellence, in collaboration with scientists from Campus Biomedico in Rome, Italy announced today the results of studies showing the emergence of a SARS-CoV-2 viral strain with a deletion in a protein known as nsp1. These data, accepted for publication today by the Journal of Translational Medicine, (link here) may indicate the emergence of a less pathogenic viral strain.
Monday, August 03, 2020
Virologist Robert Gallo, MD, has had a long and storied career in academic and government research. He is the Homer & Martha Gudelsky Distinguished Professor in Medicine, co-founder and director of the Institute Human Virology (IHV) at the University of Maryland School of Medicine and co-founder and international scientific adviser of the Global Virus Network. Despite his deep roots in HIV, Dr. Gallo’s current focus is, not surprisingly, COVID-19, which emerged in China last year and within four months morphed into a full-blown pandemic. As usual, Dr. Gallo’s research strategy has raised eyebrows. Unlike the antibody and RNA vaccines that are all the rage in COVID-19 science, Gallo is putting his energies behind repurposing the oral polio virus vaccine developed in the 1950s by Albert Sabin.

Social distancing is one of the curses of COVID-19, and may fall more heavily on people with HIV than on those without this burden. “People with HIV, and in particular certain subsets of that group—the LGBTQ community, older adults aging with HIV, etc.—face more mental health issues than the general population,” said Sarah Schmalzle, MD, an assistant professor of medicine at the Institute of Human Virology, University of Maryland School of Medicine, in Baltimore. “Many of our patients also already face significant isolation and loneliness due to a combination of HIV stigma, losses of friends and family to HIV, and aging.”
Friday, July 31, 2020
Dr. Robert Gallo, director of the Institute for Human Virology at the University of Maryland School of Medicine, joins the show to give his take on the prospects for an effective COVID-19 vaccine. Gallo is skeptical of the approach many organizations are taking with antibody vaccines, citing the similarly low efficacy those treatments had with HIV due to the low durability of the antibodies. Dr. Gallo’s research is mainly related to Oral Polio Vaccine, which he thinks needs to be tested more in regard to innate immunity.

What would you think if someone told you that we already have a vaccine that at least helps fight Covid-19? That may already be the case. Two American scientists, Dr. Robert Gallo and Dr. Konstantin Chumakov, are positing that decades-old live vaccines for things like polio and tuberculosis strengthen the immune system’s first line of defense a more general way to fight infection. And the history books show us that that sometimes translates into at least some cross-protection against completely different viruses.

CNN: There is plenty of evidence that existing inoculations such as polio vaccines protect children against a wide range of infections and it's worth trying them out against the new coronavirus, a team of experts wrote in Science magazine Thursday.
Thursday, June 11, 2020
NBC News: As the world waits for a coronavirus vaccine, some scientists are proposing that existing vaccines could give the body’s immune system a much-needed temporary boost to stave off infection. It’s still unclear whether such an approach would work, and some experts are skeptical. Others — including researchers in Israel, the Netherlands and Australia — are already investigating whether a tuberculosis vaccine could help jump-start the immune system and make COVID-19 less deadly, though the World Health Organization strongly advises against using that vaccine until it’s proven effective against the coronavirus.

(Source: Business Insider) According to the World Health Organization-China Joint Mission on COVID-19, as of February 20, 80% of laboratory-confirmed cases were mild to moderate, 14% were severe, and 6% were critical. Just to be clear, a mild case of COVID-19 is not like a mild cold. The symptoms will still be pretty severe. Anything less than needing oxygen puts you in this category. Severe cases do need supplemental oxygen, and critical ones are defined by respiratory or multi-organ failure.
