Is ringing in the ears a side effect of vaccines?


Joe Graedon and Dr. Teresa Graedon

Question: I received the Moderna vaccine. After the second shot, I developed tinnitus that has lasted five weeks (so far).

I haven’t found much about this side effect online in medical reports. However, I did find a forum with other people complaining of tinnitus that has not gone away. Have you heard of this? Can you give me some hope that it will go away in time?

Answer: As far as we can tell, the clinical trials for the Moderna and Pfizer/BioNTech vaccines did not reveal tinnitus (ringing in the ears) as a side effect. There are, however, some reports in the Vaccine Adverse Event Reporting System (VAERS) database.

We have received a couple of similar stories:

“I’ve had both doses of Moderna vaccine. After the second dose my chronic tinnitus, which was worked up extensively in the past, got louder and continues that way over a month later.”

Another person wrote: “I received my last shot of the Pfizer vaccine two weeks ago. I had COVID in June 2020, and it caused some ringing in my ears. I never connected it to COVID, though.

“Then after each injection, I got more ringing in my ears. It’s now worse than ever. Will it ever go away? I hope it is just temporary and will resolve with time.”

The possibility of tinnitus as a rare vaccine side effect should not discourage people from getting their shots. As our reader above noted, COVID infections themselves can cause tinnitus. One study found that 6.6% of hospitalized patients developed this condition (International Journal of Audiology, online, July 31, 2020). Only time will tell if the ringing will fade.


Question: Thank you for writing about authorized generic drugs. I know this topic too well, as both my teenage son and I have ADD/ADHD respectively.

I have spent months battling with pharmacies to get authorized generic methylphenidate for each of us. The new Patriot brand that uses the OROS delivery system is a true authorized generic, but it is difficult to find.

Answer: The Concerta brand of methylphenidate comes from Janssen Pharmaceuticals, a subsidiary of the Johnson & Johnson drug company. This special extended-release formulation utilizes OROS technology (osmotic-controlled release oral delivery system). The goal of such formulations is to provide a gradual and sustained blood level of the active medication.

According to GoodRx, the price of brand-name Concerta averages around $500 a month. The authorized generic (AG) from Patriot Pharmaceuticals is identical to the brand name and should be far more affordable. Getting your pharmacy to stock the Patriot AG of methylphenidate may take some arm-wrestling, though. For more information on this process, you may want to check here:


Question: I read your column about coffee being helpful against dementia. Does decaf also help? I only drink decaf, whole bean, and grind my own.

Answer: Caffeine is not the only compound in coffee that may help protect the brain. Other potentially beneficial chemicals include caffeic acid, quercetin, chlorogenic acid and trigonelline (International Journal of Molecular Sciences, Dec. 24, 2020). This suggests that decaf might be beneficial.


Question: After using a cortisone nasal spray to treat my allergies for 25 years, I lost my sense of smell. I even got thrush from using the spray at night. It ran down my throat while I was sleeping and created conditions for this fungal infection to flourish. I no longer use this type of nasal spray. Instead, I rely on quercetin. When my allergies are really bad, I occasionally take a Benadryl.

Answer: Corticosteroid nasal sprays have become very popular since they became available over the counter, because they are so effective. Regular use, however, may impact the sense of smell (Annals of Otology, Rhinology and Laryngology, April 3, 2021). Such drugs may also predispose people to fungal infections such as thrush.

Quercetin is sold as a dietary supplement. This flavonoid is found in vegetables and fruits. It stabilizes mast cells that release histamine and other inflammatory compounds (PLoS One, March 28, 2012). As a result, quercetin appears to be effective against allergies and contact dermatitis.
