Q: We hope that the COVID-19 vaccines are effective and safe. What if one of the vaccines, Moderna or Pfizer, really harms someone, not just a 24 hour nausea, fever or head ache, but something worse (blindness, loss of motor function, or death) — can you sue the company?

A: Before I answer, it’s important to note that both the Moderna and Pfizer vaccines have been found to be safe — to an unparalleled degree, some scientists say. While no is 100% safe, because each person’s body will react differently, the U.S. Centers for Disease Control and Prevention says serious adverse reactions are exceedingly rare.
