With the Johnson & Johnson vaccine, a piece of DNA from the COVID-19 spike protein is injected into an adenovirus (the kind of virus that typically causes colds). This reaction allows protection if one gets infected with the virus at a later time. In this case, the harmless “spike” protein of the virus in the mRNA vaccine triggers the secretion of antibodies and recruitment of memory immune cells in the bloodstream. The strategy has been in development for years, but this is the first time it’s been used in a distributed vaccine. Both the Pfizer/BioNTech and Moderna vaccines use messenger RNA (or mRNA). Scheraga, the side effects have to do with how the COVID-19 vaccines work. What causes these side effects?Īccording to Dr. Instead, these changes may be associated with the body’s response to stress. Though some people have reported changes in their periods shortly after vaccination, there currently is no concrete evidence that COVID-19 vaccines can have a direct effect on women’s menstrual cycles. However, the CDC maintains its stance that these reports are rare and the benefits of COVID-19 vaccination outweigh the known and potential risks. ![]() These cases predominantly occurred among teens 16 or older and adolescent males after receiving the second dose of an mRNA COVID-19 vaccine. Heart conditionsĪccording to the CDC, there have been reported cases of myocarditis and pericarditis in adolescents and young adults. ![]() The likelihood of being diagnosed with GBS after receiving the Johnson & Johnson COVID-19 vaccine is extremely small - about 0.0008%. The Johnson & Johnson vaccine has also been associated with cases of Guillain-Barré Syndrome, a rare autoimmune disorder that attacks the body’s nerves. Upon further review, these reactions were determined to be very rare, and the FDA recommended resuming the use of this vaccine. These cases occurred among women between the ages of 18 and 59, and the symptoms set in around six to 15 days after vaccination. In April, a small number of recipients of the Johnson & Johnson vaccine developed a rare blood clotting disorder. Uncommon side effectsĪs studies continue, some less common side effects have been identified. Most of the side effects occurred one or two days after vaccination. With Johnson & Johnson’s vaccine, commonly reported side effects were arm soreness, headache, muscle aches and nausea. The data shows that side effects are more commonly felt after the second dose of Pfizer or Moderna’s vaccine rather than after the first dose.
