This Year’s Flu Vaccine Was 23 Percent Effective


The LA Times passes along the news that this year’s flu vaccine gives you a 23 percent lower chance of contracting the flu:

That 23% figure is a measure known as “vaccine effectiveness,” and it’s certainly on the low end of the spectrum. In the decade since experts began calculating a “VE” for flu vaccines, it has ranged from a low of 10% to a high of 60%.

….But the vaccine didn’t help everyone equally. Kids benefited the most — the VE for those between the ages of 6 months and 17 years was 26%. Among adults, the VE was 12% for people ages 18 to 49 and 14% for people 50 and older. The figures for adults were too small to be statistically significant.

Just my luck. This year was the first time I ever got a flu shot, and all I got out of it was a 14 percent lower chance of getting the flu. And my arm was sore for days afterward! Hmmph.

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
