United States: In the wake of COVID-19 and long COVID-19, the researchers have recently listed extremely rare side effects of the vaccines against the infection. Two of the side effects have been mentioned in the largest vaccine safety study to date, according to the reports by 1news.

The experts who worked on the research paper mentioned that the vaccine against COVID-19 comes with certain complications that “overweight” the benefits offered by the vaccines.

How did the researchers unfold the conclusion?

According to the reports, the health experts conducted a detailed analysis and compared the rates of 13 brain, blood as well as health conditions among the population who have received either of the jabs – Pfizer, Moderna, or AstraZeneca. The comparison was made with the condition of the organs during the pre-pandemic phase.

Possible side-effects of possessed by vaccines!

As per 1news, the rare side-effects found after getting mRNA (Moderna and Pfizer) jabs were pericarditis (swelling of the thin sac covering the heart) and myocarditis (inflammation of the heart muscle).

Along with this, the AstraZeneca vaccine may result in causing cerebral venous sinus thrombosis (a type of brain blood clot) and Guillain-Barre syndrome (where the immune system attacks nerves).

In addition to this, two new rare side effects from the AstraZeneca vaccine were also analyzed during the study. Reportedly, the rare side-effects found in the study were Acute disseminated encephalomyelitis – the disease during which the brain and spinal cord of an individual swell and transverse myelitis – the disease results in swelling in the spinal cord.

How commonly can people get infected by the two diseases?

It is to be noted that studies have also revealed that the public has an extremely small risk of both diseases. Accordingly, 0.78 cases for every million doses were for disseminated encephalomyelitis, and 1.82 cases per million doses were for transverse myelitis.

How did experts address the study findings?

The co-director of the Global Vaccine Data Network – Professor Jim Buttery, mentioned, “For rare side effects, we don’t learn about them until the vaccine has been used in millions of people,” as per 1news.

He added, “No clinical trial can ever have the size to answer those questions, and so we only find out those questions after a vaccine has been introduced.”

Along with this, the concern was also addressed by vaccine expert professor Julie Leask, who stated that these conclusions should be considered, but our health experts have been working on the same.

She stated, “Our vaccine experts are paying attention to when vaccines lead to serious side-effects, and they’re acting on it,” adding, “Being confident in a system that will detect problems and address them is a very important part of a robust vaccination program.”

The reports have also claimed that the findings were published in the international journal Vaccine.
