No more annual flu shot? New target for universal influenza vaccine

A new antibody discovered in the blood of some people vaccinated against or infected with influenza can recognize a broad variety of flu viruses.

Scientists at Scripps Research, University of Chicago and Icahn School of Medicine at Mount Sinai have identified a new Achilles’ heel of influenza virus, making progress in the quest for a universal flu vaccine. Antibodies against a long-ignored section of the virus, which the team dubbed the anchor, have the potential to recognize a broad variety of flu strains, even as the virus mutates from year to year, they reported Dec. 23, 2021 in the journal Nature.

“It’s always very exciting to discover a new site of vulnerability on a virus because it paves the way for rational vaccine design,” says co-senior author Andrew Ward, PhD, professor of Integrative Structural and Computational Biology at Scripps Research. “It also demonstrates that despite all the years and effort of influenza vaccine research there are still new things to discover.”

First exposure to flu virus sets our immunity for life – Study

Were you born in an H1N1 year or an H3N2 year? The first type of influenza virus we are exposed to in early childhood dictates our ability to fight the flu for the rest of our lives, according to a new study from a team of infectious disease researchers at McMaster University and Université de Montréal.

The findings, published this week in the journal Clinical Infectious Diseases, provide compelling new evidence to support the phenomenon known as ‘antigenic imprinting’, which suggests that early exposure to one of the two flu strains that circulate every year imprints itself on our immunity and disproportionately affects the body’s lifelong response to the flu.

How you need to fight the flu

The flu has further tightened its grip on the U.S. This season it is now as bad as the swine flu epidemic nine years ago, according to Medical Xpress.

A government report out Friday shows one of every 13 visits to the doctor last week was for fever, cough and other symptoms of the flu. That ties the highest level seen in the U.S. during swine flu in 2009.

And it surpasses every winter flu season since 2003, when the government changed the way it measures flu.

Here are two of my weapons for fighting the flu.

“I wish that there were better news this week, but almost everything we’re looking at is bad news,” said Dr. Anne Schuchat, acting director of the Centers for Disease Control and Prevention.

Flu season usually takes off in late December and peaks around February. This season started early and was widespread in many states by December. Early last month, it hit what seemed like peak levels—but then continued to surge.

The season has been driven by a nasty type of flu that tends to put more people in the hospital and cause more deaths than other more common flu bugs. Still, its long-lasting intensity has surprised experts, who are still sorting out why it’s been so bad. One possibility is that the vaccine is doing an unusually poor job; U.S. data on effectiveness is expected next week.

I have written an entire page on fighting the flu which you can access here – How to fight the flu. For the record, I recommend flu shots. I know that this is an emotional hot button for people, so if you are against them fine. Your call. I am aware that this year’s flu shot was off as far as nailing the virus and it has been called only 10 percent effective. Okay, that is not as good as the usual round of vaccinations, but I will still take it against no shot. In addition, doctors tell me that if you get the flu after the shot, it is a less virulent dose and you recover faster, also you don’t spread flu germs as much as an unvaccinnated person.

I would like to conclude with a very down to earth recommendation that I hope you will heed. Keep your hands clean. You can bring flu bugs into your body by touching a dirty surface and moving your hands to your face. The virus enters through your open mouth, nose and eyes. If you ride public transportation, wear gloves to hold on to the strap or pole. You don’t know who held it previously or what germs they were carrying. Likewise, in your public dealings. I live in a high rise building. So, I touch a lot of surfaces, elevator buttons, door handles, etc. that others touch. So, I am carrying hand wipes as well as a liquid disinfectant that I rub on my hands.

The flu is hardy and can survive on surfaces for a day. A common way to catch it is to touh your face after  you touch an infected surface. Pay attention and don’t touch your face before washing your hands.

Here is what the CDC says about flu germs spread:

Person to Person

People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses are spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth or nose.

To avoid this, people should stay away from sick people and stay home if sick. It also is important to wash hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand rub. Linens, eating utensils, and dishes belonging to those who are sick should not be shared without washing thoroughly first. Eating utensils can be washed either in a dishwasher or by hand with water and soap and do not need to be cleaned separately. Further, frequently touched surfaces should be cleaned and disinfected at home, work and school, especially if someone is ill.

The Flu Is Contagious

Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 1 to 4 days after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms. During this time, those persons may still spread the virus to others.

We have long weeks ahead of us till the flu threat abates, stay clean.

Flu Outbreaks Spike – CDC

As if the current bone-chilling cold snap (can you say Polar Vortex?) weren’t enough to worry about six days into the new year, flu outbreaks have spiked in the latest week, according to the Centers for Disease Control (CDC). Unfortunately for those of us affected by the cold, it aggravates the situation. As we huddle together to keep warm, we help to spread the virus, according to Dr. Manny Alvarez on Fox News. In addition, “the immune system in your body doesn’t work properly when you have temperatures below zero,” also “viruses love the cold and wet,” he concluded.

Some 25 states are now reporting widespread flu outbreaks. This is a jump of 10 from the previous week.

So far, two children died as a result of flu this week. The total now stands at six flu-associated pediatric deaths.

It appears that the current virulent strain is striking the young and middle-aged very hard.

Despite the apparent lateness in the season, doctors say it is still not too late to get your flu shot. Doctors report that it reduces your risk of catching the flu by 70 percent.

The map displays the widespread nature of the flu till December 28, the latest graphic data available.

I have written repeatedly about combating the flu. You can read details on my Page – How to fight the flu.

Here are some FLU PREVENTION TIPS:

Avoid close contact with sick people.

Cover sneezes and coughs with tissue or crook of elbow, not hands.

Wash hands often with soap and water.

Drink plenty of fluids, but not alcohol.

Get a flu shot.
