Joshua and Alexandra Price say they and their two children were mistakenly given the Covid-19 vaccine instead of a flu shot a week ago at their local pharmacy — and they are now dealing with some adverse symptoms.

The Prices took their 4- and 5-year-olds to the Walgreens in Evansville, Indiana, on October 4 for their yearly shots. About 90 minutes later the pharmacist called saying they had made a mistake. The entire family had been injected with adult doses of the Covid-19 vaccine.
