A study from Case Western Reserve University found that young men were up to six times more likely to develop myocarditis after COVID-19 infection compared to those who received the vaccine. The highest rate was seen in young men (18-29 years). A recent report from the CDC estimated the rate of this rare effect at approximately 3.5 cases per million complete vaccine series. The cases tended to be mild and self-limited (meaning the patients recovered without intervention). Myocarditis - This is inflammation of the heart muscle that was detected within days of vaccination with mRNA vaccines.It’s much more common to get Guillain-Barre syndrome after a viral infection, including COVID-19, than it is to develop the condition from a vaccine. A recent report from the CDC estimated the rate of this rare effect at approximately 7.8 cases per million doses. Guillain-Barre syndrome - This is a rare syndrome, causing a temporary paralysis, that occurred within days of vaccination of the adenoviral vector vaccine.A study from the University of Oxford found that the risk of cerebral venous thrombosis after COVID-19 infection was nearly 15 times higher compared to the rate following vaccination. It was more common in women of child-bearing age. A recent report from the CDC estimated the rate of this rare effect at approximately three cases per million doses. Thrombosis with thrombocytopenia syndrome (TTS) - This is a rare syndrome of blood clots (cerebral venous thrombosis) associated with low platelets that occurred within a few weeks of vaccination of the adenoviral vector vaccine (the Johnson & Johnson vaccine).There are several robust safety monitoring systems in place for these vaccines that can detect the very rare adverse events, including: The vaccines have been shown to be extremely safe. Going back at least as far as the polio vaccine, which was widely released to the public in the 1960s, we’ve never seen a vaccination with long-term side effects, meaning side effects that occur several months or years after injection.Īnd, in every vaccine available to us, side effects - including rare but serious side effects - develop within six to eight weeks of injection.ĬOVID-19 vaccines have been studied in humans for more than a year now, and more than 174 million people have been fully vaccinated in the United States alone. One thing we can do is look at all vaccines we’ve produced and studied over time. It’s a concern for many who are still hesitant to get the COVID-19 vaccine: How could we possibly know whether long-term side effects are possible, when COVID-19 vaccines just began clinical trials in 2020?

Because of the profound implications of information/ misinformation sharing through these platforms, the situation has come to a point wherein experts cannot weigh their opinion on such a crucial topic.Editor’s note: As what we know about COVID-19 evolves, so could the information in this story. More so, in a space where public expression is meant to be the key. The incident, however, highlights how the lack of accurate information around several theories is blurring the line between facts and misinformation. Twitter marking it as misinformation is hence, not a completely baseless move. Note that Luigi's tweet claimed that people vaccinated with mRNA-based vaccines shed spike proteins, an idea that has repeatedly been rejected by scientists from around the world. Though that still means that he will be locked out of his Twitter account until Twitter reviews the appeal. Luigi could appeal for the said violation being a mistake, and he did. Though it was not specified which rules were violated by the tweet, it is likely that the content was marked for misinformation. A report on the tweet left Luigi with only an option of deleting it for violating Twitter Rules.

The appeal was to contest Twitter's decision to block the content from public view.
