It’s time to give flu vaccine another shot
WASHINGTON — 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.
According to the CDC, everybody, starting at 6 months of age, should get the vaccine.
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?”
Not enough people get vaccinated, 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.
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.
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.
