Please get a flu shot

It’s always a good idea, even if it’s more effective in some years than in others.

The flu vaccine may not be very effective this winter, according to U.S. health officials who worry this may lead to more serious illnesses and deaths.

Flu season has begun to ramp up, and officials say the vaccine does not protect well against the dominant strain seen most commonly so far this year. That strain tends to cause more deaths and hospitalizations, especially in the elderly.

Only 48 percent of the 85 samples of H3N2 influenza viruses that have been tested since Oct. 1 are closely related to the strain that was picked for the vaccine distributed in North America, according to the agency.

“Though we cannot predict what will happen the rest of this flu season, it’s possible we may have a season that’s more severe than most,” said Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, at a news conference Thursday.

CDC officials think the vaccine should provide some protection and still are urging people to get vaccinated. But it probably won’t be as good as if the vaccine strain was a match.

Flu vaccine effectiveness tends to vary from year to year. Last winter, flu vaccine was 50 to 55 percent effective overall, which experts consider relatively good.

Current flu vaccines are built to protect against three or four different kinds of flu virus, depending on the product. The ingredients are selected very early in the year, based on predictions of what strains will circulate the following winter.

The ingredients always include a Type A H3N2 flu virus. The most severe flu seasons tend to be dominated by some version of that kind of flu bug. The three most deadly flu seasons of the last 10 years – in the winters of 2003-2004, 2007-2008, and 2012-2013 – were H3N2 seasons.

In March, after the H3N2 vaccine strain was vaccine production was underway, health officials noted the appearance of a new and different strain of H3N2. “This is not something that’s been around before,” Frieden said.

But health officials weren’t sure if the new strain would become a significant problem in the United States this winter until recently, they said. Lab specimens from patients have shown that the most commonly seen flu bug so far is the new strain of H3N2. Specifically, about 48 percent of the H3N2 samples seen so far were well matched to what’s in the vaccine, but 52 percent were not, the CDC said.

Not perfect, but your odds are still a lot better with the vaccine than without. As the story notes, in an average year about 24,000 Americans die from the flu. I’ll have to check my math on this, but I’m pretty sure that’s more than the number of Americans that die from Ebola. (Which we still need to fight against as well, but Congressional Republicans have lost interest in Ebola since it’s not generating scary cable news stories any more.) So don’t fall for the hysteria. Please put the odds in your favor and get a flu shot, OK? Thanks.

Some things you can vaccinate against

Saying dumb things isn’t one of them.

CM Jack Christie

As the council considered a proposal Wednesday to accept $3.1 million in federal funding for childhood immunizations, Councilman Jack Christie voiced his opposition to the measure, apparently conflating it with flu vaccinations.

“I’m going to vote against this,” Christie said before the 15-1 vote. “You don’t die from the flu.”

Christie backed down somewhat from his comment on Friday. What he meant to say, he said, was that “People should not die from the flu.”

“First of all, that’s $3 million that the federal government doesn’t really have,” Christie said of the funding proposal. “It’s borrowed money we eventually have to pay back. But more important is the media’s embellishment of the extreme fear of encouraging flu vaccinations.

“Every year there’s going to be a flu,” he said, “and vaccines create synthetic immunity, which does not trump natural immunity to disease.”

Christie, who said he has never taken a flu shot, suggested the medical community should focus more attention on prescription drug abuse that claims thousands of lives annually in the U.S.

Dr. Joshua Septimus, associate professor of internal medicine at Methodist Hospital in the Texas Medical Center, called Christie’s comments irresponsible.

“That is totally wrong,” he said. “The flu kills anywhere from a few thousand to tens of thousands in the U.S. alone. There is very good evidence that the flu shot reduces deaths from the flu. That flu vaccine is a very low risk and with very high potential benefits.”

So much here to deal with. First, the idea that not accepting this funding is fiscally responsible is ludicrous. This money has already been appropriated. Not accepting it doesn’t mean it magically gets transmuted from a liability to an asset on the federal budget balance sheet. It means it gets to be granted to some other city. There are sometimes good reasons to turn down federal funding, but this is money for childhood immunizations. Spending money to keep kids healthy is about the best spending we can do. It’s an investment with a big payoff, both in terms of spending less later on sick kids, and the greater lifetime earnings potential of kids who grew up healthy and in some cases who got to grow up at all.

Second, the bit about the medical community needing to focus more on prescription drug abuse is a complete non sequitur. Last I checked, the medical community was big enough to handle more than one thing at a time. It’s also unlikely to change its priorities based on one screwball City Council voting down a grant for childhood immunizations. If you want to send a message to the American Medical Association, writing a letter to them is probably the better approach.

Finally, and not to put too fine a point on it, but even Helena Brown voted to accept these funds. Let me say that again: Even Helena Brown voted to accept these funds. When you’re off on an island that even Helena Brown isn’t inhabiting, you need to check your coordinates, know what I mean?
