They discover a new side effect of Moderna’s vaccine:

The coronavirus vaccination campaign is working even better than expected, as the effect of the vaccines exceeds that shown in previous trials and they will be effective even with new variants that may appear.

Large-scale administration of the vials among the population will achieve herd immunity, a necessary goal to emerge from the pandemic and return to normal life.

However, while vaccines work and are necessary, it is also true that they can cause some side effects that are bothersome in people who are vaccinated. The most common are fatigue, generally feeling unwell, pain in the arm where the injection was given, and fever..

A study which was conducted in the United States and which has just been published on the Jama Network platform reveals a new symptom of Moderna’s vaccine to be taken into account: the COVID arm.

Symptoms of this side effect include erythema, itching, hardness and pain when touching the area where the vaccine was received. This is a delayed skin reaction because it appears one week after the vaccine is inoculated, although it tends to go away a few days later.

The COVID arm can appear 7 days after the first dose or 2 days after the second, as shown by the 16 patients with skin reactions the study studied.

Research indicates that these side effects are mild and do not present a risk for the patient, although they can cause pain and skin hypersensitivity. The finding also indicates that this reaction was not found in patients vaccinated with Pfizer, the other messenger RNA vaccine currently in use around the world.

Although there have been previous reports on reactions which occur mainly with the Moderna vaccine, its appearance can be bulky.

Moderna’s vaccine can cause the reaction known as the ‘Covid arm’

What is the “Covid arm”

Reports of a rash after vaccinations, commonly known as “COVID arm”, started appearing on a Facebook group of pharmacists in early 2021. They shared their experiences in the “Pharmacy Staff for COVID-19 Support” group, posting images of large red circles on their arms. People wondered what community members of 44,000 knew about this occurrence and if others were seeing similar effects.

While most reactions developed in the shoulder and upper arm near the injection site, others developed in the elbow, fingers and palm, according to the study. In some cases, the tissue below the skin’s surface has hardened and lost its smooth appearance in response to the inflammation.

Other side effects of Moderna’s vaccine

The most common are pain, redness and swelling in the arm where the vaccine was given. as well as fatigue, muscle pain, headache, chills, fever, and nausea.

It is important to keep in mind that any side effects mentioned, both in this vaccine and in other vaccines, should go away within a few days.

What do we know about the safety of Moderna’s vaccine?
