Multi-dose flu shot has only 25 mcg of mercury - most commercial fish contain 23 mcg of mercury per 8 ounces of fish

Are multi-dose vials less expensive?

Economics are a bit complicated due to wastage with multiple vials:

Most of the Western world, apart from the US, has moved on to single vials:

Whenever possible, CDC recommends that single-use vials be used and that multi-dose vials of medication be assigned to a single patient to reduce the risk of disease transmission (http://www.cdc.gov/injectionsafety/patients/syringeReuse_faqs.html).

Where to get a thimerosal/mercury-free flu shot?

Many local Costco stores carry only single vials and the cost is $14.99 if no insurance is used. The availability of additional options may improve immunization rates.

Search for a Costco pharmacy near you here, and call them to verify availability: Warehouse Locations - Costco: www.costco.com/warehouse/locator.aspx

Personal Flu Stories - CDC:



Each year in the US, nearly 20,000 children under age 5 are hospitalized due to flu-related complications. CDC recommends that children aged six months through 18 years old get a flu vaccination. Moving personal stories help parents and caregivers learn about the dangers of influenza to children and the benefits of vaccination.

65-yo patient received a standard-dose flu shot already this season. Should she get the high-dose shot too? Or get a second regular flu shot?

A 65-yo female patient received a standard-dose flu shot already this season. Should he get the high-dose shot too? Or try to get a second regular flu shot?

The simple answer is no. The patients should consider herself immunized. Studies show that getting a delayed second dose doesn't necessarily increase antibody response, and there's some concern that it might actually have a negative effect on the immunity. If you've already had the regular seasonal dose, wait until next year for another dose.

From CDC's Immunize.org website:

Sometimes patients age 65 years and older who have received the standard-dose influenza vaccine hear about the high-dose product (Fluzone High-Dose, sanofi) and want to receive that, too. Is this okay to administer?

No. ACIP does not recommend that anyone receive more than one dose of influenza vaccine in a season except for certain children age 6 months through 8 years for whom two doses are recommended.

Would giving an older patient 2 doses of standard-dose influenza vaccine be the same as administering the high-dose product?

No, and this is not recommended.
