RFK Jr. to remove controversial ingredient from all flu vaccines in the US
Source: USA Today
Health Secretary Robert F. Kennedy Jr. signed a controversial recommendation July 23 from a vaccine panel that advised removing thimerosal from all influenza vaccines.
Thimerosal is a preservative that has largely been phased out of U.S. vaccines and has long been targeted by anti-vaccine advocates despite broad scientific consensus on its safety.
The call against thimerosal was first presented by Lyn Redwood, former leader of Children's Health Defense, an anti-vaccine group founded by Kennedy, during a June 26 meeting for the Advisory Committee on Immunization Practices.
During the meeting, ACIP members voted against recommending certain vaccines to contain thimerosal, despite widespread disapproval from the medical community.

KEY POINTS
- Thimerosal is a mercury-based preservative that has been used for decades in the United States in multi-dose vials (vials containing more than one dose) of medicines and vaccines.
- There is no evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site.
- In July 1999, the Public Health Service agencies, the American Academy of Pediatrics, and vaccine manufacturers agreed that thimerosal should be reduced or eliminated in vaccines as a precautionary measure.
About thimerosal
Mercury is a naturally occurring element found in the earth's crust, air, soil, and water. Two types of mercury to which people may be exposed methylmercury and ethylmercury are very different.
Methylmercury is the type of mercury found in certain kinds of fish. At high exposure levels methylmercury can be toxic to people. In the United States, federal guidelines keep as much methylmercury as possible out of the environment and food, but over a lifetime, everyone is exposed to some methylmercury.
Thimerosal contains ethylmercury, which is cleared from the human body more quickly than methylmercury, and is therefore less likely to cause any harm.
Purpose of thimerosal
Thimerosal is added to vials of vaccine that contain more than one dose (multi-dose vials) to prevent growth of germs, like bacteria and fungi.
Introduction of bacteria and fungi has the potential to occur when a syringe needle enters a vial as a vaccine is being prepared for administration. Contamination by germs in a vaccine could cause severe local reactions, serious illness or death. In some vaccines, preservatives, including thimerosal, are added during the manufacturing process to prevent germ growth.

(8,240 posts)I would think that in a mass vaccination campaign, they would go through vials pretty quickly.
The UK has banned thimerosal for years, so not sure how big an impact it would really have.

(10,072 posts)So it should not affect mass vaccination.
Single doses are better on many levels - because if a pharmacist doesnt shake the multidose flu vials just right or forgets to shake it between patients - different amts of ingredients can be injected into people - too much shaking and bubbles can be injected. Also, no one wants an infant to be injected with mercury just because some pharmacy is too cheap to buy single dose vials.

(6,610 posts)... We vaccinate over a thousand employees.
Thimerosal makes this possible, because it allows multiple doses in the same container. Without it, we would need over a thousand single dose units, and more time per injection.
I hope we can continue our mass vaccination campaigns despite this unnecessary cost and complication.
womanofthehills
(10,072 posts)- so it should have very little effect. Most people dont even know a small percentage of flu vaccines still have mercury and I have yet to meet someone who would get a vaccine with mercury if they knew they could get a mercury free vaccine.
Trouble with multi dose - the needle doesnt always draw up equal amounts of vaccine. The person who gets the first dose might have a totally different amt of ingredients than the one who pulls the last dose.
TheRickles
(2,888 posts)And even if only a small percentage of vaccines still use it, the ideal % would be zero. Similar to mercury in dental fillings - amalgam is now being replaced by resin composites. Safer substitutes are available for both vaccines and fillings, so we should use them (apart from what you think of RFK Jr's other policies).

The amount of mercury in a flu shot is about the same as in a serving of salmon. I guess salmon is bad for our health.
Mass vacination campaigns rely on multi dose units, which are made possible by thimerosal. Prohibiting thimerosal complicates and increases the expense of mass vacation campaigns, which - needlessly - erodes public health efforts.

Also, please tell me you are pushing for everyone to stop eating fish.
womanofthehills
(10,072 posts)Everyone believed ethyl mercury was safer than methyl mercury because they could still find methyl mercury in blood up to 100 days - after a week studies said they could find no ethyl mercury in blood. But some recent studies said when they tested both mercurys on monkeys - both had both types in their brains.
There was a much higher proportion of inorganic Hg in the brain of thimerosal monkeys than in the brains of MeHg monkeys (up to 71% vs. 10%). Absolute inorganic Hg concentrations in the brains of the thimerosal-exposed monkeys were approximately twice that of the MeHg monkeys. Interestingly, the inorganic fraction in the kidneys of the same cohort of monkeys was also significantly higher after im thimerosal than after oral MeHg exposure (0.71 ± 0.04 vs. 0.40 ± 0.03). This suggests that the dealkylation of ethylmercury is much more extensive than that of MeHg.

Consumer Reports recommends avoiding Abacore tuna as some cans they tested had mercury way over gov limits. Some Abacore was not recommended for anyone to eat.
Abacore is the largest tuna so it has the most mercury. Other tunas they recommend not eating more than once a week.

(31,192 posts)RFK Jr may be a nutcase, but I support what he is doing when it comes to pushing changes that other countries have already made. We have been held back on health initiatives because of the profit concerns of big corporations.
Dental amalgams contain elemental mercury. Ethyl mercury is what's in Thimerasol. The amount is miniscule and does not stay in the body nearly as long as Methylmercury.

(520 posts)The concentration in the brain was for inorganic Hg, which is not the organic form which is the more concerning form. The brain concentrations are noted as being high, but the actual effect of that is not known other than a high number of microglia cells (immune system) being present. The other measures for ethyl mercury confirm that it clears the system far more quickly the methlymercury, even in the brain, save for the questions about the inorganic form. I'm fine with more research, but I tend to doubt that any research reference by RFKjr is being quoted properly.
Total Hg derived from im thimerosal is cleared from the infant M. fascicularis much more quickly than MeHg. The washout T1/2 of total blood Hg after im injections of thimerosal in vaccines is much shorter than the T1/2 of MeHg (6.9 vs. 19.1 days).
A much lower brain concentration of total Hg was observed in the thimerosal monkeys compared with the MeHg monkeys, that is, a 3- to 4-fold difference for an equivalent exposure of Hg. Moreover, total Hg is cleared much more rapidly from the brain after thimerosal than after MeHg exposure (24 vs. 60 days).
Absolute inorganic Hg concentrations in the brains of the thimerosal-exposed monkeys were approximately twice that of the MeHg monkeys. Interestingly, the inorganic fraction in the kidneys of the same cohort of monkeys was also significantly higher after im thimerosal than after oral MeHg exposure (0.71 ± 0.04 vs. 0.40 ± 0.03). This suggests that the dealkylation of ethylmercury is much more extensive than that of MeHg.
Previous reports have indicated that the dealkylation of Hg is a detoxification process that helps to protect the central nervous system (Magos 2003; Magos et al. 1985).

(20,006 posts)The type in vaccines has been proven safe and easily excreted, as is evidenced by the fact that, 20 yr after we stopped using it, there has been no drop in autism rates or chronic diseases.
Of course, that makes sense since you're quoting a 20 yr old article. The question it asked then has been answered.

.... as soon as the seal is pieced, those pesky pathogens can get at it. They might even be on a new needle.
Another factor may be logistics and handling. Single doses used infrequently at a doctor's office can be kept refrigerated. A large number, thousands, of multidose vials for a mass campaign can be shipped without refrigeration, and stored for use without a massive on site refrigeration unit. Reported below that refrigeration is required regardless.
In fact, since there is no reason to forgo the preservative, those advantages could be gained throughout the health system by simply using it for all vials, and forgoing the single dose units. We are wasting public health resources for no good reason. We are doing so based on FUD - irrational fear, uncertainty and doubt.

Notably, this is from a site that is against Hg in vaccines. But it appears refrigeration is probably standard in developed countries.
