Do Vaccines Cause Bell’s Palsy?

We don’t usually know what causes Bell’s Palsy, so that makes it a perfect candidate for some people to think it’s a vaccine injury.

Mercola cites a study that looked at VAERS reports, so none of the cases were verified to see if they were actually caused by a vaccine. And he fails to mention all of the real studies that found no association between vaccines and Bell's Palsy!

And for anti-vaccine folks to use in their propaganda to scare you away from vaccinating and protecting your kids.

What Causes Bell’s Palsy?

Although we may not always know what causes it, Bell’s Palsy is fairly easy to diagnose.

“Bell’s palsy is a nerve problem that affects the muscles of your face. It causes weakness or partial paralysis of the muscles on one side of your face. With Bell’s palsy, your eyelid may not close properly and your smile may seem uneven.”

What Is Bell’s Palsy?

So what causes it?

“Bell’s palsy occurs when the nerve that controls the facial muscles is swollen, inflamed, or compressed, resulting in facial weakness or paralysis. Exactly what causes this damage, however, is unknown.”

Bell’s Palsy Fact Sheet

Most experts think that Bell’s Palsy is caused by a viral infection, which leads to swelling and inflammation of the facial nerve. That’s likely why steroids and antiviral medications, like acyclovir, are often helpful treatments.

“The prognosis for individuals with Bell’s palsy is generally very good. The extent of nerve damage determines the extent of recovery. Improvement is gradual and recovery times vary. With or without treatment, most individuals begin to get better within 2 weeks after the initial onset of symptoms and most recover completely, returning to normal function within 3 to 6 months.”

Fortunately, most people with Bell’s Palsy, which mainly affects adults, get better.

Do Vaccines Cause Bell’s Palsy?

Bell’s Palsy was first described by Sir Charles Bell in 1821.

There are reported cases before that though, with the earliest by Cornelis Stalpart van der Wiel (1620-1702) from The Hague, The Netherlands in 1683.

And no, we didn’t have any vaccines in 1683.

That’s not to say that vaccines couldn’t cause Bell’s Palsy.

One vaccine, an inactivated intranasal influenza vaccine that was only used in Switzerland during the 2000-01 flu season, was associated with an increased risk of Bell’s Palsy.

Why? It was likely because of the enzymatically active Escherichia coli Heat Labile Toxin (LT) adjuvant that was used in the vaccine, which is not something you find in any of the vaccines we now use.

While you might find an occasional case report about a vaccine and Bell’s Palsy, remember that a case report published about one patient isn’t strong evidence that it wasn’t a coincidence.

It should be reassuring to everyone that plenty of studies have been done confirming that other vaccines we use do not cause Bell’s Palsy. And even in the case of that flu vaccine, the association was quickly discovered and the vaccine was discontinued.

In fact, since vaccines, especially the chicken pox vaccine and Tdap, can prevent infections that actually cause Bell’s Palsy, if you are worried about Bell’s Palsy, get vaccinated!

  1. I know it was no coincidence that the 2nd day after the flu shot bell’s palsy struck me I could sense the drug wasn’t the right thing to have in me right from the start but once injected it was to late the reason I got the injection to begin with is the year prior I was sent out on deployment for nysdot and got the flu from a co worker on deployment with me so the following year I was coming up for deployment again and choose the shot to protect me while on deployment but instead chronic bells palsy got me instead so don’t tell me it is only coincidence but I will never get a flu shot again and with all experimental drugs there should be a preinjection blood test first that is my feeling on that Ron sturdevant

  2. I got bell’s palsy the morning after receiving tdap and MMR vaccines as a child. Lasted 6 months
