While the analysis found that several rare but non-life-threatening side effects on the skin were possible, researchers noted that skin sores or bumps known as pernio or chilblains—also described as "COVID toes" by some patients—were also reported, USA Today reports. The condition, which was also reported to affect the fingers in 10 percent of patients who saw the symptom, is likely caused by inflammation of blood vessel walls and can cause digits to swell and turn deep red or purple.
Fortunately, researchers say reacting to your shots with discolored digits is not a sign that anything is seriously wrong. "Having your toes turn purple is uncomfortable but it's not a reason to not get the second dose," Esther Freeman, MD, PhD, director of global health dermatology at Massachusetts General Hospital and senior study author, told USA Today.

People have reported experiencing a metallic taste in their mouth as a side effect of the vaccine…The taste is "like having nickels in your mouth," a South Carolina patient named John Howard told NBC News. "It's certainly not debilitating or anything like that, but I do hope it goes away. I would like my coffee to taste normal."
While it may seem strange, Creech notes the metallic taste is not a side effect to be concerned about. It does not "indicate anything that would prevent getting the second dose of vaccine," he said.

And, in the Pfizer trial, there were 47 cases of anaphylaxis. https://www.eatthis.com/news-surprising-side-effects-covid-vaccine/
