Dr. Alvin Lin answered

Any flu shot better : Than none. Thimerosal is preservative used in multi-dose vials of flu vaccines while single-dose vials are preservative free. Other than that, there is no difference between the actual active flu shot. The preservative is used to prevent contamination when a multi-dose vial is punctured several times. Check out http://www.Mayoclinic.Com/health/complex-regional-pain-syndrome/ds00265 for more info.
