Health researchers are learning more about the vaccine's possible side effects as more patients get it. The Centers for Disease Control and Prevention (CDC) recently revised its catalog of COVID-19 vaccine side effects, adding muscle pain, nausea, and injection site redness to the list.

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, prepares to receive his first dose of the COVID-19 vaccine at the National Institutes of Health.

It's also apparent that the side effects are negligible after nearly three months of vaccines in North America, Europe, Israel, and other regions. Pain at the injection site and brief flu-like symptoms are the most common side effects, particularly after the second dose.

Researchers cautioned that one minor COVID-19 vaccine side effect, BGR reported. The article said skin problems such as redness and rashes could occur several days after the first or second dose, rather than instantly. These side effects were observed after receiving Moderna injections, especially after the first dose. They're not dangerous, and they usually go away on their own after a few days.

COVID-19 Vaccine: What Are The New Side Effects?

There are nine potential coronavirus vaccine side effects mentioned in the latest recommendations. People can feel redness in addition to pain and swelling on the arm where the shot is given. The CDC also added muscle pain and fatigue to the list of systemic reactions. Muscle pain should not be associated with injection-related pain.

Muscle ache

On March 5, the CDC revised its vaccine recommendations, including muscle pain as one of the "common side effects."

According to the CDC, this is a different symptom from the discomfort you might be feeling in the arm where you got your jab.


The CDC has now added nausea to its list. The sense of being ill is referred to as nausea.

See a doctor if the sensation does not go down for a few days or if it returns.

The injection site is red

Another recent side effect of being aware of after vaccination is redness at the injection site.

This site impact may manifest itself dramatically after you have received your inoculation in rare cases.

Initially, the department identified six possible side effects. As seen below, two of the symptoms are local (pain and swelling), and four are systemic (fever, chills, tiredness, and headache).

COVID-19 Vaccine: Are These Side Effects Dangerous?

These reactions indicate that the immune system is gaining immunity in response to the vaccine's potential danger. Antibodies to the coronavirus should occur two weeks after the first injection. Full protection should be achieved two weeks after the second injection.

The recommendations also include advice on how to cope with side effects.

"Talk to your doctor about taking over-the-counter medicine, such as ibuprofen, acetaminophen, aspirin, or antihistamines, for any pain and discomfort you may experience after getting vaccinated," the guidelines read. "You can take these medications to relieve post-vaccination side effects if you have no other medical reasons that prevent you from taking these medications normally."

People should apply cold, damp cloths to the vaccine area and use or exercise their shoulder to relieve pain and irritation after vaccination. The general side effects that can appear may be alleviated by drinking lots of water and dressing gently.

According to the CDC, if these side effects do not go down in a few days, people should contact their physicians. People should also see a doctor if the redness or tenderness of their arm worsens within 24 hours. The CDC also warns people that taking drugs before vaccination is not advisable to avoid side effects.
