Johnson & Johnson’s Covid-19 vaccine now warns of possible rare neurological side effects.The problem can be dealt with, but the update marks The second safety issue of vaccines in the past three months.
The new potential side effects are Guillain-Barre SyndromeThis is a rare reaction that causes the immune system to attack the nerves, causing muscle weakness and, in some cases, paralysis.
Johnson & Johnson Vaccine fact sheet The information provided to clinicians was updated on Monday, pointing out that reports of adverse events after vaccination indicated that the risk of Gilan-Barre increased within 42 days after receiving the injection.
It is worth noting that federal health authorities have not yet discovered a causal relationship between Johnson & Johnson’s vaccine and the Gillan Barre report. Anyone can get Guillain-Barre, and it is estimated that between 3,000 and 6,000 people are affected each year. Centers for Disease Control and Prevention.
The syndrome can appear after viral or bacterial infection. It has also been observed as a side effect of certain drugs and vaccinations.
The J&J vaccine, developed by the company’s Janssen subsidiary, uses an adenovirus that causes the common cold. This virus has been modified so that it is not infectious, but it can still perform the task of delivering a payload of genetic material into cells. Cells use this material to replicate the spike protein of the new coronavirus, thereby prompting the immune system to produce antibodies. This is a different method from that used by messenger RNA vaccines, which use lipid nanoparticles to reach their cellular targets. The use of the mRNA Covid vaccine has not been reported to cause Guillain-Barre.
according to Mayo ClinicThe treatment of this syndrome includes plasmapheresis or plasma exchange, and immunoglobulin therapy, which includes the infusion of healthy antibodies from blood donors. The CDC says that although some people will experience permanent nerve damage, most people with Guillain-Barré disease will fully recover.
Johnson released statement Acknowledge the risks of Gillan Barre.
“We strongly support raising awareness of the signs and symptoms of rare events to ensure that they can be quickly identified and effectively treated,” part of the statement said.
The updated vaccine information warns patients about symptoms including weakness or tingling, especially in the legs or arms, which can worsen and spread to other parts of the body; difficulty walking; double vision or inability to move eyes; and incontinence.
The new warning to Gillan-Barre was issued after reports of thrombosis related to Johnson & Johnson’s vaccine in the spring. The FDA and CDC temporarily stopped using the vaccine in April, while conducting an investigation to assess safety risks. On April 23, the order to authorize emergency use of vaccines was Fix The risk of marking blood clots in the brain and other parts of the body is increased, and symptoms appear within one to two weeks after vaccination.
