The most common side effects after vaccination include:
Pain, swelling, or redness where the shot was given
Muscle and joint aches
Vaccines work by tricking the body into thinking it has a virus and mounting a defence against it.
That may cause arm soreness, fever, headache, muscle aches or other temporary symptoms of inflammation that can be part of that reaction.
For many, the side effects are more powerful after the second dose is administered.
Health experts say these side effects are just normal signs your body is building the immune response it needs to protect you from severe disease.
Soreness after being vaccinated is a sign that your body is developing an immune response to the vaccine.
To treat the pain, the Centers for Disease Control and Prevention suggests applying a “clean, cool, wet washcloth” to the site of the injection.
Other methods to help include using warm compresses.
Moving the arm will also help to reduce soreness as opposed to just staying still which will increase muscle soreness.
For a fever, the CDC recommends people drink lots of fluids and dress lightly.
Rest and relaxation will help with the fatigue and tiredness.
Many doctors suggest people avoid scheduling their vaccine appointment before a busy day, so they’re able to rest if they feel sluggish afterward.
The Norwegian Medicines Agency are currently investigating the cause of 13 deaths so far and concluded that common adverse reactions of mRNA vaccines, such as fever, nausea, and diarrhoea, may have contributed to fatal outcomes in some of the frail patients.
Side effects shouldn’t last longer than 48 hours after getting the shot, and they often fade sooner than that.
However, if you’re experiencing side effects days after getting the COVID-19 vaccine, contact a doctor.
