What side effects are known and expected for the approved mRNA vaccines?
After nearly 15 million mRNA vaccine doses administered, Swissmedic has so far evaluated approximately 15'000 reports of side effects.
The most common side effects after receiving the mRNA vaccine include soreness at the injection site, fatigue, headache, muscle soreness, chills, joint pain, nausea, vomiting, and fever. These symptoms occur up to seven days post vaccination and tend to be stronger after the second dose.
Reports of serious allergic reactions are extremely rare. A report issued by the Center for Disease Control and Prevention (CDC) in the United States indicates that, on average, 1 person in 100,000 (Pfizer/Biontech vaccine) or 1 person in 400,000 (Moderna vaccine) had experienced a serious adverse allergic reaction.
The Swiss FOPH has also released a video on this subject.
