Mercury in Vaccines vs Tuna Fish Sandwich

Introduction:
Which contains more mercury?
Flu vaccine from a Multidose Vial or a Tuna Fish Sandwich?

From another FDA page: Advice about Eating Fish
"For children, a serving is 1 ounce at age 2 and increases with age to 4 ounces by age 11."

1 ounce of Tuna, canned light (includes skipjack): 1 oz x 28.35 = 28.35 grams x .144 ppm = average of 4.08 micrograms of mercury. Three servings for a week's recommendation, equals a total of 12.25 micrograms.
This very small "sandwich," even repeated 3 times, contains LESS total mercury than the 12.5 micrograms of mercury in a single pediatric dose of flu vaccine from a multidose vial.

On the other hand, 1 serving of Tuna, albacore/white tuna, canned or fresh/fresh frozen would have an average of .350 ppm to .410 ppm meaning at .410 ppm the mercury content would be 11.6235 micrograms of mercury. This is the recommended total for one week and again is LESS than the 12.5 micrograms of mercury in a single pediatric dose of flu vaccine from a multidose vial.

So under current recommendations, a flu vaccine from a multidose vial does contain more mercury than a serving of tuna recommended for a 2 year old child or younger. Ingested mercury is 90% excreted quickly whereas injected mercury is slow to leave the body and may cross the blood-brain barrier to damage the brain. Thus the effective poisoning from eating a "tuna fish sandwich" is significantly less than the poisoning from the mercury in a flu vaccine from a multidose vial even when the actual amount of mercury in a fish is greater than 12.5 micrograms.

For children older than 2 years, the amount of allowable mercury in fish increases and thus becomes more than the 12.5 micrograms of mercury in a pediatric flu vaccine but when the difference between ingestion and injection is taken into account, it is clear that the EFFECTIVE amount of mercury in a tuna fish sandwich is far less than "allowable" mercury from a multidose vial of flu vaccine.

Mercury in vaccines may be up to 50 TIMES more toxic to the brain than mercury in fish
03/02/2017 / By Tracey Watson [Vaccines.News]
They noted that although methylmercury is considered dangerous in even tiny amounts, the World Health Organization (WHO) approves small doses of thimerosal in multiple vaccines taken repetitively during pregnancy and childhood. With this in mind, they compared the toxicity and potential harm of both etHg (ethylmercury) and meHg (methylmercury).

Their study abstract states: “In vitro studies comparing etHg with meHg demonstrate equivalent measured outcomes for cardiovascular, neural, and immune cells. And then it gets really interesting, because they note that since the two types of mercury have different toxicity profiles, in vivo testing indicated that, “in real-life scenarios, a simultaneous exposure to both etHg and meHg might result in enhanced neurotoxic effects in developing mammals.” [Emphasis added]

So, not only are both types of mercury equally bad, but exposure to both would compound their toxic effects. That means, for example, that exposure to ethylmercury in a vaccine, combined with exposure to methylmercury in a tuna fish sandwich, would result in even greater harm.

Thimerosal and Vaccines 02/01/2018
.../thimerosal-and-vaccines
"A vaccine containing 0.01% thimerosal as a preservative contains 50 micrograms of thimerosal per 0.5 mL dose or approximately 25 micrograms of mercury per 0.5 mL dose. For comparison, this is roughly the same amount of elemental mercury contained in a 3 ounce can of tuna fish."

Thimerosal Content of Available FDA-Approved Seasonal Influenza Vaccines .../thimerosal-and-vaccines#table


[Editor's note: A .5 mL dose is an adult dose. A pediatric dose is half that amount.
Also note that these mercury content figures are for multi-dose vials containing mercury as a preservative.

A single dose vial of flu vaccine will have less than 1 microgram of mercury (trace amount),

Half size dose (pediatric) in a multidose vial contains about 12.5 micrograms of mercury,

Full size dose in a multidose vial contains about 25 micrograms of mercury.

See below for a discussion of how much mercury a 6 ounce serving of tuna might contain from a UK website. Current recommendations [2019] from the FDA would put 6 ounces as two ounces more than the 4 ounce recommended adult serving, clearly not suitable for children.]

How often should I eat tuna? [Excerpts below are from article:]

Tuna is a widely eaten species of fish. However, canned tuna is often the most common source of mercury in the diet.

The term tuna encompasses several species of fish, including skipjack, albacore, yellowfin, and bigeye. Skipjack is the most commonly consumed species.

...
There are two main types of canned tuna: White albacore and chunk light.

Chunk light is made mostly from skipjack tuna, a smaller species of tuna. Albacore tuna is a larger species and contains higher levels of mercury.

Canned white albacore tuna typically contains about 0.32 parts per million of mercury. Canned light tuna contains about 0.12 parts per million of mercury.

The following table contains the recommended amount of canned tuna that an individual should eat according to their body weight:

The figures in the table above are taken from U.S. Food and Drug Administration (FDA) test results for mercury and fish, and the Environmental Protection Agency's (EPA) determination of safe mercury levels.

The FDA recommends avoiding fresh albacore tuna and tuna steak during pregnancy. It is only safe to eat up to one serving of less than 170 g per week. Canned tuna, however, is safe to eat during pregnancy.
...
[Ed Note: 170 grams = 6 ounces. 170 grams x .12 parts per million, from above sentence equals 20 micrograms of mercury in a 6 ounce serving.]

New advice from the FDA, Content current as of: 07/02/2019, says "For children, a serving is 1 ounce at age 2 and increases with age to 4 ounces by age 11." Recommended for light tuna, 2 to 3 servings per week. Albacore/white-Tuna only 1 serving per week. Source: https://www.fda.gov/food/consumers/advice-about-eating-fish
