In the fight against the corona pandemic, more and more people are opting for a corona vaccination. Currently, mRNA vaccines from Biontech / Pfizer and Moderna, as well as vector vaccines from AstraZeneca and Johnson & Johnson are used for vaccination. After vaccination, so-called vaccine reactions can occur. Headache, fatigue, and flu-like symptoms are common post-vaccination symptoms, both when vaccinated with mRNA and vector-based vaccines. According to the Robert Koch Institute (RKI), the most common local reaction is pain at the sting site.
Corona vaccination: that’s why the arm hurts after vaccination
Not all people experience symptoms after vaccination. With all three vaccines, however, the most common physical reactions occur after vaccination Aches oa feeling of pressure in the affected location. The pain can resemble the sensation of a sore muscle. They also occur in 84.1 percent of the vaccinated redness or swelling up. Many people are upset when they notice these symptoms. However, they are not a cause for concern and can also occur with a flu shot.
In general, pain after a vaccination is a good sign as it shows us that the body is reacting to the vaccination. Because according to the Paul Ehrlich Institute (PEI), the formation of antibodies usually occurs during the sting itself. For this reason, it is not uncommon for the arm to be red, swollen, or tender. People with well-functioning immune systems usually react faster and more forcefully to the so-called local reactions. In most cases, local reactions occur within hours of vaccination and can last for a few days.
On purpose: A study by the American health authority FDA concluded that even with booster vaccination with the Biontech vaccine, about 83% of vaccinated people experienced pain at the injection site.
Covid arm: skin hypersensitivity reaction
Vaccination with Biontech / Pfizer and Moderna vaccines, both mRNA vaccines, can also cause a so-called Covid arm in vaccinated people. The term was used more widely in the United States and Canada: the phenomenon was initially dubbed “Modern arm” by the media until it became clear that the Biontech / Pfizer vaccine could cause the same reaction.
Covid arm symptoms mainly appear a few days after vaccination – the skin around the injection site may become red, swollen, hot, and itchy. Symptoms are harmless and disappear after about four to five days. In early March, a safety report from the Paul Ehrlich Institute (PEI) stated: “These delayed local reactions can occur about a week after vaccination and are characterized by a well-defined redness of the skin and swelling of the vaccinated armin some cases associated with pain and / or itching. “Due to the time interval, PEI assumes a hypersensitivity reaction of the skin, which is related to the buildup of the body’s immune system. If the Covid arm occurs after vaccination, this has no effect on the second vaccination. According to the IEP, there is no reason to “suspend or delay the second dose of vaccination in those affected.” However, straining the arm or exercising after vaccination is not recommended.

Clinical studies have shown that women in particular would be affected after vaccination with mRNA vaccines. It is not yet clear why some people react more strongly than others.
