What’s Viral Shedding?

/in /by

Based on the response to my email about the flu vaccination, people raised a few questions and I had one of my own. The first question is about viral shedding. Your first thought is probably “What’s that?”

Viral shedding is the period of time when you’re infected and can transmit the flu virus to someone else—it’s when you’re contagious. The question from the reader wondered whether someone who has been vaccinated will still be contagious to others if they’re infected with the flu. The answer is yes; being vaccinated against this year’s flu will not inhibit your ability to infect others if you get the flu. Remember, some people who are vaccinated will still get the flu.

The problem with the flu is that you can be shedding the virus while you still feel fine. You can be infectious up to a day before the onset of symptoms and up to 24 hours past the end of the fever. The difference may be related to the form of flu, whether influenza A or B. However, the data are not completely clear.

The point is that you should still be cautious if you begin to feel symptoms, whether vaccinated or not. While you can’t catch the flu from the vaccination because the virus used is dead, you might still get the flu. The goal is to protect others. Speaking of others, we’ll talk about herd immunity on Thursday.

What are you prepared to do today?

The Big Chill: Do You Need a Flu Shot?

/in /by

In this final installment of The Big Chill, I’m going to take a look at flu shots: should you get one or not? Before I do that, a word about echinacea.
Echinacea
Many readers have read that echinacea shouldn’t be used long term or used at all if you have an autoimmune disease such as rheumatoid arthritis. The problem is that there are no studies to support either position and no studies to suggest it’s harmful, either. In that situation, the approach is always to proceed with caution until we know more. The only problem with waiting . . .

The Big Chill: Immune-Boosting Supplements

/in /by

Getting ready for cold and flu season, let’s turn to dietary supplements that may help keep your immune system strong. Dozens of supplements are promoted to strengthen the immune system, but let’s stick to what I know works based on the research and my experience: echinacea, garlic, and vitamin C.

Make sure you read this first before you go to the amounts of each supplement to take below because in this case, close enough is. Don’t obsess about the difference between 200 mg or 250 mg, and if I say 300 mg three times a day, don . . .

If you live almost anywhere in the continental U.S. and Canada, you’re in for some chilly weather for the next 10 days at least, so it’s time to boost your immune system for the cold and flu season. Let’s start where your immune system starts and that’s your gut. You guessed it—we’re talking about the microbiome, the 100 trillion or so microbial organisms that live in and on our bodies and contribute to our health.

There are three ways to give your microbiome a boost:
