The flu
forecast is cloudy and it’s too soon to know if the U.S. is in for a third
miserable season in a row, but health officials said Thursday not to delay
vaccination.
While the
vaccine didn’t offer much protection the past two years, specialists have
fine-tuned the recipe in hopes it will better counter a nasty strain this time
around.
“Getting
vaccinated is going to be the best way to prevent whatever happens,” Dr. Daniel
Jernigan, flu chief at the Centers for Disease Control and Prevention, told the
Associated Press.
Last
year’s flu brought double trouble: A new strain started a second wave of
illnesses just as the first was winding down, making for one of the longest
influenza seasons on record. The year before that marked flu’s highest death
toll in recent decades.
So far,
it doesn’t look like the flu season is getting an early start, Jernigan said.
The CDC urges people to get their flu vaccine by the end of October. Typically
flu starts widely circulating in November or December, and peaks by February.
“Painless,”
Health and Human Services Secretary Alex Azar pronounced after getting his own
flu shot at a news conference Thursday.
If people
shrug at the risk, “it’s not just about you,” Azar said. “Vaccinating yourself
may also protect people around you,” such as how newborns have some flu
protection if their mothers were vaccinated during pregnancy.
Scientists
are hunting for better flu vaccines, and the Trump administration last week
urged a renewed effort to modernize production. Most of today’s vaccine is
produced by growing flu virus in chicken eggs, a 70-year-old technology with
some flaws. It takes too long to brew new doses if a surprise strain pops up.
And intriguingly, newer production techniques just might boost effectiveness.
For now,
people who get vaccinated and still get sick can expect a milder illness – and
a lower risk of pneumonia, hospitalization or death, stressed Dr. William
Schaffner of Vanderbilt University and the National Foundation for Infectious
Diseases.
He’s been
known to tell such patients, “I’m always glad to see you’re still here to
complain.”
Here are
some things to know:
Who needs vaccine?
Everybody,
starting at 6 months of age, according to the CDC.
Flu is
most dangerous for people over age 65, young children, pregnant women and
people with certain health conditions such as heart disease, asthma or other
lung disorders, even diabetes.
But it
can kill even the young and otherwise healthy. On average, the CDC says flu
kills about 24,000 Americans each year. Last year, 135 children died.
Parents
wouldn’t “drive off with their child not restrained in a car seat, just in case
they’re in an accident,” said Dr. Patricia Whitley-Williams, a pediatrician
with Rutgers Robert Wood Johnson Medical School. “So why would you not
vaccinate your child against the flu?”
How many get vaccinated?
Not
enough, the CDC says. Because flu mutates rapidly, a new vaccine is needed
every year. Last year, 45% of adults and 63% of children got vaccinated,
according to figures released Thursday.
Some
groups do a little better. Nearly three-quarters of children under age 5 were
vaccinated last year, and just over two-thirds of seniors.
How bad will this year be?
Flu is
one of medicine’s most unpredictable foes.
For
example, last fall started off fairly mild. But in February, a strain notorious
for more severe illness, called H3N2, suddenly popped up. Worse, even though
each year’s vaccine contains protection against H3N2, the circulating bug had
mutated so it wasn’t a good match. A vaccine that had worked well for the first
few months of flu season suddenly wasn’t much use.
But if
that harsh bug returns, this year’s vaccine has been updated to better match
it.
Lots of options
Manufacturers
say up to 169 million vaccine doses will be available this year, and people can
ask about different choices. Most will offer protection against four flu
strains.
Traditional
flu shots are for all ages. For needle-phobic adults, one brand uses a
needle-free jet injector that pushes vaccine through the skin. And the FluMist
nasal spray is for generally healthy people ages 2 through 49, who aren’t
pregnant.
Two
brands are specifically for the 65-plus crowd, whose weakened immune systems
don’t respond as well to traditional shots. One is high dose, and the other
contains an extra immune-boosting compound. Those brands protect against three
flu strains, including the more typically severe ones.
And
people allergic to eggs have two options, one brand grown in mammal cells
instead and another made with genetic technology and insect cells.
No-egg vaccines gaining new interest
Newer
technologies could speed production, which is currently a six-month process.
But
there’s another reason going egg-free is getting scientists’ attention: Certain
strains change a bit while growing in chicken eggs, an adaptation that
can make the resulting vaccine a little less protective.
It’s
mainly a problem for those worrisome H3N2 strains. While it’s not clear how
much difference that makes, Schaffner said some doctors already consider using
egg-free brands for high-risk patients.
Other steps to take
Cover
coughs and sneezes. Wash your hands frequently during flu season. One recent
study showed washing is better than hand sanitizers.
Ask about
anti-flu treatments if you’re at high risk of complications.
And most
important, stay home if you’re sick to keep from spreading the misery.
