The 2020 COVID-19 (coronavirus) pandemic resulted in several companies competing to make vaccines. One of those companies was Pfizer, Inc. (pronounced without the “p,” like “FI-zer”), a company founded in New York City in 1849.

“Hearing reports that people who’ve taken the vaccine do report one side effect - they can’t hear themselves go to the toilet. Pfizer are yet to issue a statement on whether there’s a silent pee” was posted on Twitter by James on November 10, 2020. “There’s a urinary side effect to the new Pfizer vaccine. It makes your p silent” was posted on Sickipedia on December 2, 2020.

“P” is, of course, a pun on the word “pee.”

“Got my Pfizer vaccine this morning. Pfeeling pfine!” is a related Pfizer joke.

Hearing reports that people who’ve taken the vaccine do report one side effect - they can’t hear themselves go to the toilet. Pfizer are yet to issue a statement on whether there’s a silent pee.

Don’t expect to hear yourself urinate after taking the Pfizer vaccine.
I had a doctor tell me the P was silent.
