Time for flu shots — getting one is more important than ever!
Wondering when to get your flu shot? The best time is before influenza (flu) starts circulating widely. For most people, September or October is ideal for protection through the whole flu season, as the immune response from the vaccine wanes over time. And while changes and restrictions due to COVID-19 may make getting a flu vaccine less convenient for some this year, the pandemic makes it more important than ever. Why do I need to get a flu vaccine yearly? Influenza A and Influenza B cause most cases of flu in humans. Both have many strains that constantly change, accumulating genetic mutations that disguise them from the...

Cough, Cough, Hack, Hack, It’s Flu Season Again
While reading one of my favorite magazines yesterday, NATURAL HEALTH, I ran across a small list of facts about the flu compiled by a fellow writer, Kate Wertheimer. Depending on your propensity for yukiness, you may want to read this list with caution however, we’re all out there together getting exposed to all those live viruses who often are being carried by folks with little if any sense about how contagious they are. We’ll get to her list later, which was compiled in New Zealand. Apparently they do a great deal of research in most countries about the strains of viruses they can and will choose for their flu inocula...

1977 H1N1 influenza virus is not relevant to the gain of function debate
Image credit The individuals who believe that certain types of gain-of-function experiments should not be done because they are too dangerous (including Lipsitch, Osterholm, Wain-Hobson,) cite the 1977 influenza virus H1N1 strain as an example of a laboratory accident that has led to a global epidemic. A new analysis shows that the reappearance of the 1997 H1N1 virus has little relevance to the gain-of-function debate. Human influenza viruses of the H3N2 subtype were circulating in May of 1977 when H1N1 viruses were identified in China and then Russia. These viruses spread globally and continue to circulate to this day. Th...

Influenza A viruses in bats
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another reservoir with even greater genetic diversity. A new influenza virus had previously been isolated from little yellow-shouldered bats (Sturnira lilium) in Guatemala. Three of 316 rectal swabs were positive when tested by a pan-influenza polymerase chain reaction assay. Viral sequences were also detected in liver, intestine, lung, an...

What ’s new with the flu shot?
Should you get the influenza (flu) vaccine this year? The short, quick answer (barring any medical reasons you shouldn’t, such as severe allergies), is yes! But recent research raises another important question: When should you get the shot? Why a flu shot every year in the first place? Getting infected with the flu can be dangerous — we’ve seen patients in the ICU who were previously healthy but had a horrible response to a strain of the virus and became very sick. Every year the Centers for Disease Control and Prevention (CDC) and other agencies release flu vaccination guidelines in late summer to early fall. The f...

Pharma Needs to Step Up & Help Develop a Universal Flu Vaccine
Discussion with Ian Wilson").It's great to be a small part of the history of virology, but it would be even better if that history eventually includes the successful development of a universal vaccine for the flu. And this is where the drug industry needs to step in according to Bloomberg View:"[T]he government has limited means and little product-development experience. Making a new vaccine typically takes a decade and can cost $1 billion. A project of that size is better suited to large pharmaceutical companies. Most, however, have been loath to seriously invest in new vaccines, which offer low returns."Given this market...

The value of influenza aerosol transmission experiments
A Harvard epidemiologist has been on a crusade to curtail aerosol transmission experiments on avian influenza H5N1 virus because he believes that they are too dangerous and of little value. Recently he has taken his arguments to the Op-Ed pages of the New York Times. While Dr. Lipsitch is certainly entitled to his opinion, his arguments do not support his conclusions. In early 2013 Lipsitch was the subject of a piece in Harvard Magazine about avian influenza H5N1 virus entitled The Deadliest Virus.  I have previously criticized this article  in which Lipsitch calls for more stringent H5N1 policies. More recently Lipsi...

CDC Reports Flu Widespread, Google Search Trends Alarming
According to new surveillance statistics released on Friday from the Centers for Disease Control and Prevention (CDC), forty-seven states in the U.S. are now reporting widespread influenza activity [1]. The virus, which first appeared in the Southeast, has reached epidemic levels. Forty-seven states have reported widespread geographic influenza activity (i.e. incidence of flu) for the week between December 30, 2012 and January 5, 2013, and twenty-four states and New York City have reported high influenza-like illness (ILI) activity (i.e. the proportion of outpatient visits to healthcare providers for influenza-like illne...

Influenza H5N1 x H1N1 reassortants: ignore the headlines, it’s good science
Those of you with an interest in virology, or perhaps simply sensationalism, have probably seen the recent headlines proclaiming another laboratory-made killer influenza virus. From The Independent: ‘Appalling irresponsibility: Senior scientists attack Chinese researchers for creating new strains of influenza virus’; and from InSing.com: ‘Made-in-China killer flu virus’. It’s unfortunate that the comments of several scientists have tainted what is a very well done set of experiments. Let’s deconstruct the situation with an analysis of the science that was done. It is known that avian inf...

Is it Time for Your Flu Shot or Extra Nutrition?
Conclusions Flu vaccinations have caused serious disease and death, including miscarriages, Guillain-Barré Syndrome, and influenza. The influenza vaccine has been reported to be effective zero to 50% of the time. Safer practices exist to build one’s immune system and stay healthy this winter. Some suggestions for avoiding illness include eating nutrient-dense foods, taking vitamins C and D, resting and detoxifying through Epsom salt baths.

65-yo patient received a standard-dose flu shot already this season. Should she get the high-dose shot too? Or get a second regular flu shot?
A 65-yo female patient received a standard-dose flu shot already this season. Should he get the high-dose shot too? Or try to get a second regular flu shot?The simple answer is no. The patients should consider herself immunized. Studies show that getting a delayed second dose doesn't necessarily increase antibody response, and there's some concern that it might actually have a negative effect on the immunity. If you've already had the regular seasonal dose, wait until next year for another dose.Image of the H1N1 Influenza Virus, CDC.From CDC's Immunize.org website:Sometimes patients age 65 years and older who have received...

Flu shots during pregnancy
Is your head already spinning from all of the confusing information about the safety of routine vaccinations? Well, news of the latest findings regarding the flu vaccine during pregnancy certainly won’t help things. A group of researchers recently reported an association between a pregnant woman getting the flu vaccine and having a miscarriage. The authors were clear that the study could not establish that flu shots cause miscarriage. It could only report the observation that, in this small group of women, miscarriage was slightly more common within 28 days of getting the flu shot. But only in women who had also gotten a...

Reconstruction of 1918-like avian influenza virus stirs concern over gain of function experiments
The gain of function experiments in which avian influenza H5N1 virus was provided the ability to transmit by aerosol among ferrets were met with substantial outrage from both the press and even some scientists; scenarios of lethal viruses escaping from the laboratory and killing millions proliferated (see examples here and here). The recent publication of new influenza virus gain of function studies from the laboratories of Kawaoka and Perez have unleashed another barrage of criticism. What exactly was done and what does it mean? According to critics, virologists should not be entrusted to carry out gain of function studie...

Influenza virus in breast milk
During breastfeeding, mothers provide the infant with nutrients, beneficial bacteria, and immune protection. Fluids from the infant may also enter the mammary gland through retrograde flux of the nipple. Studies in a ferret model reveal that influenza virus replicates in the mammary gland, is shed in breast milk and transmitted to the infant. Virus may also travel in the opposite direction, from infant to mother. The role of the mammary gland in influenza virus transmission was studied using a ferret model comprising lactating mothers and nursing infants. Intranasal inoculation of nursing mother ferrets with the 2009 H1N1 ...
