Early safety data from the first month of COVID-19 vaccination finds the shots are as safe as the studies suggested they’d be.
Everyone who experienced an allergic response has been treated successfully, and no other serious problems have turned up among the first 22 million people vaccinated, according to the Centers for Disease Control and Prevention.
The data was collected from several tracking systems, including a voluntary one in which people who are vaccinated report their symptoms via text. Another allows people who believe they have been harmed by a vaccine to contribute their information, and a third collects reports from medical records.
Although it’s never possible to prove something is completely safe, data from these tracking systems suggests the vaccines are not causing large numbers of unusual or dangerous results.
