Remember last year, when flu vaccine shortages left you scrambling for a shot? The CDC recommends lining up now to preempt the bugs that can knock you to your knees and boost your viral load.  A recent review of 328 HIVers in Japan found that 21% of those who didn’t get a vax got the flu, while only 6% of those vaccinated got sick. Call Doc or your druggist for a shot.
