A new study says side effects from the COVID-19 vaccines are a lot less common than you'd think.

The study found that a large number of side effects reported by patients after receiving their shot can be attributed to the placebo effect.

The placebo effect occurs when people anticipate certain effects from a medical treatment so much so, that they feel the symptoms they were expecting.

As COVID-19 cases continue to spread in the U.S., experts say this information could be key to getting more people vaccinated.
