Has This Really Been the Longest Flu Season in a Decade?

Many folks were probably surprised by reports that this has been the longest flu season in ten years.

After all, just about everything about this year’s flu season has likely seemed mild compared to last year.

“There have been 21 straight weeks of elevated flu season in the U.S., making the current 2018-2019 flu season the longest in ten years.”

CNN

But here we are.

Has This Really Been the Longest Flu Season in a Decade?

What does it really mean to have 21 straight weeks of elevated flu season?

Where is it elevated and by how much?

“Influenza-like-illness levels have been elevated for 21 weeks this season, breaking the previous record of 20 weeks set during the 2014-2015 flu season.”

Situation Update: Summary of Weekly FluView Report Week 15

It’s likely that the media reports have been generated by a statement in the latest Weekly FluView Report that influenza-like-illness levels have been elevated for a little longer than usual this season.

What does that mean?

Well, influenza-like-illness levels are the proportion of outpatient visits for influenza-like illness (ILI), or basically, how many people are going to the doctor with flu symptoms. Once we get above the national baseline of 2.2%, we know that flu season has started.

“The proportion of outpatient visits for influenza-like illness (ILI) decreased to 2.4%, but remains above the national baseline of 2.2%. Seven of 10 regions reported ILI at or above their region-specific baseline level.”

And it ends when we get back below 2.2%.

Flu season is the time we spend above the national baseline level of influenza-like illness activity.

What’s missing in the talk of the longest flu season, is that it doesn’t tell you much about the severity of the flu season. For example, the peak ILI this year was well below that of last year.

And flu season doesn’t start and end at the same time all over the country.

The bottom line? This has been an average flu season and a lot of people still died, including at least 91 children.

So whether it is a long or short flu season, severe or mild, get a flu vaccine and be protected.

Did Dr. Bob Uncover a CDC Plot to Give Adult Flu Shots to Babies?

Have you heard the news?

Uh, the ACIP can't request a license for a vaccine...
Uh, the ACIP can’t request a license for a vaccine…

Dr. Bob and his new podcasting side kick think that the “CDC wants the FDA to approve adult doses of the flu vaccine for babies, because the normal half-doses approved for babies don’t work well enough.”

Did Dr. Bob Uncover a CDC Plot to Give Adult Flu Shots to Babies?

This is likely going to surprise Dr. Bob, but many infants already get the same dose of flu vaccine as adults.

Both FluLaval and Fluarix are given at the same 0.5ml dose, containing 15 µg of HA per vaccine virus, to infants, older children, and adults.

Fluzone, on the other hand, is still given at a 0.25ml dose, containing 7.5 µg of HA per vaccine virus, to children between the ages of 6 months to three years, and a larger 0.5ml dose to older kids and adults.

Why the differences?

“In a randomized trial comparing immunogenicity and safety of 0.5 mL FluLaval Quadrivalent with 0.25 mL Fluzone Quadrivalent, safety and reactogenicity were similar between the two vaccines.”

Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices—United States, 2018–19 Influenza Season

Because they are just as safe at the lower doses and might actually work better.

Then why did we ever use a lower dose for infants?

That recommendation was based on the older, whole-virus version of the flu shot, which did cause more side effects for infants when given at a full dose. We now use split-virus flu shots that don’t have this problem.

And now, the manufacturer of Fluzone has done a study, and not surprisingly, they have also found that “safety profile of a 0.5 ml (full-dose) is similar to 0.25 ml (half-dose) and may be more immunogenic.”

So they are submitting a BLA to the FDA for the use of the 0.5ml dose of their flu vaccine for infants.

What about the idea of an “adult dose of mercury” for infants?

Over 80% of flu vaccines were thimerosal free this year. You almost have to go out of your way to get your kids a flu vaccine with thimerosal, so no, this won’t mean an “adult dose of mercury” for your infant.

Most importantly though, if you understand how vaccines work, you know that the dose of vaccines for kids and adults is not calibrated by weight or age, so none of this really matters. The immune reaction that helps antibodies travel all through your body starts locally, near where the vaccine was given, so a 20-pound infant and a 200-pound adult can get the same dose of flu shot and both can be protected.

Flu Season Predictions

No, I can’t see into the future…

I predict that I will continue to get a flu shot each year, at least until they come out with a universal flu vaccine.
I predict that I will continue to get a flu shot each year, at least until they come out with a universal flu vaccine.

But some things are very easy to predict.

Flu Season Predictions

Here are some predictions for this year’s flu season.

  1. We will have a flu season epidemic in the United States this year. Surprised by that prediction? Don’t be. Flu activity reaches epidemic levels each and every year. What we don’t always have are flu pandemics, during which flu activity is very high in multiple parts of the world. By definition, flu season is an epidemic.
  2. Almost all states will eventually report having widespread influenza activity as flu season peaks. Again, this is not a bold prediction. It happens every year. How severe is flu season going to be? No one can really predict that, but we can look at the proportion of people seeing their health care provider for influenza-like illness (ILI) and laboratory-confirmed influenza-associated hospitalization rates as flu season moves along to get some idea. Remember, measures of the geographic spread of the flu don’t really tell you anything about the severity of flu activity.
  3. Dozens of kids will die with the flu – most of them unvaccinated. Remember, 37 kids died in the mildest flu season we had.
  4. A little under half of adults will get a flu vaccine, even though the current recommendation is that everyone who is at least six months old without a true contraindication get vaccinated each year.
  5. A little over half of parents will get their kids a flu vaccine.
  6. Some people who get a flu vaccine will still get the flu. You know the flu vaccine isn’t the most effective, but it still has plenty of other benefits, so even if you did still get the flu, hopefully you got a milder case, weren’t hospitalized, and didn’t die.
  7. Some people who get a flu vaccine and get the flu will blame their flu shot, even though it is well known that the flu shot can’t give you the flu.
  8. Many people who aren’t high risk will be prescribed Tamiflu. Or Xofluza, because it is new.
  9. Tens of thousands of adults will die with the flu. Even in a mild flu season, the flu is very deadly.
  10. Some folks will continue to push the idea that there is a vaginal spermicide in flu shots, even though that anti-vaccine talking point has been refuted a thousand times already.

What else can you predict about flu season?

Some folks will think it is too late to get a flu shot.

It isn’t.

Get your flu shot if you haven’t and get protected for the rest of flu season.

Another bold prediction? Elderberry syrup and Oscillococcinum are not going to help prevent or treat your flu symptoms.

Did a Healthy NY Senator Die After Getting a Flu Shot?

Update: the medical examiner has ruled that Senator José Peralta, of Queens, passed away from natural causes, complications of acute promyelocytic leukemia.

Anti-vaccine folks are heavily pushing the idea that José Peralta, a New York State Senator, died as the result of getting a flu shot.

Senator Peralta did not die of a severe allergic reaction.
All of the same things? Exactly? Senator Peralta did not die of a severe allergic reaction. He died of sepsis.

While Senator Peralta did die several days after getting a flu shot, it appears that he had already been sick for several weeks. And no, that doesn’t mean that the flu shot made him even sicker.

“The senator would be disappointed to find that conspiracy theorists are using his death to forward their agenda by misrepresenting the facts.”

Chris Sosa on No Evidence New York Legislator Died from Flu Shot

New York State Sen. José Peralta had reportedly just gotten his flu shot at a public event, where he was encouraging others in his community to get protected with free flu shots.

Senator Jose Peralta partnered with a local hospital to help get members of his community free flu shots.
Senator Jose Peralta partnered with a local hospital to help get members of his community free flu shots.

And while he did die about four days later, there is absolutely no reason to think that his getting a flu shot was connected to his death.

Anti-vaccine folks have no shame, as they not only don’t respect the privacy of Senator Peralta’s wife, children, family and friends, but also are using him to attack his legacy.

Of course, this is the method of operation of the modern anti-vaccine movement. They make folks think that anything and everything is a vaccine injury and they actually go out of their way to exploit people who have died.

Learn the Risk of falling for anti-vaccine propaganda.

There is no evidence that New York State Senator Jose Peralta died from getting a flu shot.

In fact, the medical examiner has ruled that he had acute promyelocytic leukemia when he died.

Don’t let anti-vaccine folks dishonor his legacy by pushing false stories about flu shotsscaring people away from getting vaccinated and protected.

Vaccines are safe, effective, and necessary.
