Generally, the consequences after vaccination can be mild, temporary and similar to other known vaccinations. However, according to scientific research and monitoring of known cases, the consequences of the COVID-19 vaccines are different for each person.
Rare sequelae reported by the CDC with COVID-19 vaccines are allergic reactions, such as anaphylaxis; They also reported that just over 1,000 Americans vaccinated with Pfizer-BioNTech and Moderna suffered from heart inflammation, possibly caused by these vaccines. They also reported that approximately a small percentage of Americans who received the J & J vaccine developed Guillain-Barré syndrome. And as of November 2021, the CDC and FDA have recorded 54 J&J vaccinated people diagnosed with a bleeding disorder called thrombocytopenia syndrome (TTS).
According to the latest Pharmacovigilance Report, which monitors the side effects of vaccines, he explained that the most reported sequelae are the known common effects, however there are those that have been reported less frequently, such as arthralgia, which is a joint pain that can be accompanied by inflammation or pain inside the joint itself. Tinnitus, which is an auditory sensation without an external cause, paresthesia is a burning or tingling sensation on the skin without cause, and hypoesthesia, which is a decrease in the intensity of sensations.
The scientists say they have found some severe and few recurring cases, but concluded that the risk of severe illness from COVID-19 is much greater than the risk of side effects.
Vaccinated persons should be aware of the sequelae of the vaccines and notify health professionals of any adverse reaction that lasts more than three days.
