The J&J vaccine has also been linked to an increased risk of Guillain-Barré Syndrome, a rare disorder in which the immune system attacks nerve cells. 16, 2021, the CDC had recommended the Pfizer/BioNTech and Moderna shots over J&J’s. Although TTS remains rare, because of the availability of mRNA vaccines, which are not associated with this serious side effect, the FDA on May 5 limited authorized use of the J&J vaccine to adults who either couldn’t get one of the other authorized or approved COVID-19 vaccines because of medical or access reasons, or only wanted a J&J vaccine for protection against the disease. As of early April, the syndrome has been confirmed in 60 cases, including nine deaths, after more than 18.6 million doses of the J&J vaccine.

Early symptoms of the condition, which is known as thrombosis with thrombocytopenia syndrome, or TTS, can appear as late as three weeks after vaccination and include severe or persistent headaches or blurred vision, leg swelling, and easy bruising or tiny blood spots under the skin outside of the injection site.Īccording to the CDC, TTS has occurred in around 4 people per million doses administered. The Johnson & Johnson vaccine has been linked to an increased risk of rare blood clots combined with low levels of blood platelets, especially in women ages 30 to 49.


The CDC has also noted that most patients who were treated “responded well to medicine and rest and felt better quickly.” Early evidence suggests these myocarditis cases are less severe than typical ones. Health officials have emphasized that vaccine-related myocarditis and pericarditis cases are rare and the benefits of vaccination still outweigh the risks. The rate for 18- to 24-year-old males was 52.4 cases and 56.3 cases per million doses of Pfizer/BioNTech and Moderna vaccines, respectively. are highest in males 16 to 17 years old after the second dose (105.9 cases per million doses of the Pfizer/BioNTech vaccine), followed by 12- to 15-year-old males (70.7 cases per million). There is evidence that the Pfizer/BioNTech and Moderna mRNA vaccines may rarely cause inflammation of the heart muscle (myocarditis) or of the surrounding lining (pericarditis), particularly in male adolescents and young adults.īased on data collected through August 2021, the reporting rates of either condition in the U.S. Also, those who shouldn’t receive one type of COVID-19 vaccine should be monitored for 30 minutes after receiving a different type of vaccine. People who have had a serious allergic reaction to a previous dose or one of the vaccine ingredients should not be immunized. To make sure serious allergic reactions can be identified and treated, all people receiving a vaccine should be observed for 15 minutes after getting a shot, and anyone who has experienced anaphylaxis or had any kind of immediate allergic reaction to any vaccine or injection in the past should be monitored for a half hour. Approximately 5 per million people vaccinated have experienced anaphylaxis after a COVID-19 vaccine, according to the CDC. Fortunately, these reactions are rare, typically occur within minutes of inoculation and can be treated.

history.”Ī small number of severe allergic reactions known as anaphylaxis, which are expected with any vaccine, have occurred with the authorized and approved COVID-19 vaccines. As the Centers for Disease Control and Prevention has said, these vaccines “have undergone and will continue to undergo the most intensive safety monitoring in U.S. The vast majority of people experience only minor, temporary side effects such as pain at the injection site, fatigue, headache, or muscle pain - or no side effects at all. and only a few, very rare, safety concerns have emerged. More than half a billion doses of COVID-19 vaccines have now been administered in the U.S.
