Like most vaccines, the new Coronavirus vaccines come with their own side effects. These include fevers, muscle aching, headaches, fatigue, and soreness around the injection area.

For example, the Moderna vaccine trials included “severe” side effects which included 8.9% myalgia (muscle pain) and 9.7% fatigue. These events were “generally short-lived”, according to the company, and are subject to change with further ongoing analysis of the study data.

According to CNBC, Patsy Stinchfield, a nurse practitioner at Children’s Hospital and Clinics of Minnesota, said, “if you feel something after a vaccination, you should expect to feel that.”

She added, “When you do, it’s normal to have some arm soreness or fatigue, some body aches and maybe even a fever.”

Any vaccine can cause side effects, and there are mostly minor and tend to go away within several days.

“We’re going to have to accept that there are going to be risks — nothing we do in this world is risk-free,” Dr. Grace Lee, a professor of pediatrics at the Stanford University School of Medicine and a member of the Advisory Committee on Immunization Practices for the CDC.

 She added, “Of course, we want perfect data, but given where we are in the pandemic right now, we have to find that balance.”
