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.
