Guillain-Barré Syndrome: FDA marks Johnson & Johnson injections as “small” risk | Coronavirus pandemic news

US health officials have issued new warnings about rare neurological reactions in people vaccinated with Johnson & Johnson’s disposable vaccine.

US regulators have added a new warning to Johnson & Johnson’s COVID-19 vaccine, warning that it is related to a rare and potentially dangerous neurological reaction.

The U.S. Food and Drug Administration (FDA) announced a new warning on Monday, flagging reports of Guillain-Barré syndrome, a disease of the immune system that can cause muscle weakness and occasional paralysis. Health officials describe this side effect as “the risk that people who get the vaccine may face is very small.”

The new warning will be included in a pamphlet sent to Johnson & Johnson vaccinated people. The regulator said that if they experience any symptoms, including tingling, difficulty walking and double vision, they should seek medical attention.

The action was taken after the FDA and the Centers for Disease Control and Prevention (CDC) reviewed reports of approximately 100 people experiencing the syndrome after receiving a single dose of the vaccine. The FDA said that almost everyone was hospitalized and one person died.

When the body’s immune system mistakenly attacks some of its nerve cells, Guillain-Barré syndrome occurs, causing muscle weakness and sometimes even temporary paralysis. According to the Centers for Disease Control and Prevention, an estimated 3,000 to 6,000 people in the United States suffer from this syndrome each year.

The number of reported cases related to Johnson & Johnson’s vaccines accounts for only a small percentage of the nearly 13 million people vaccinated in the United States. Most cases are reported as men—mostly men 50 years and older—usually around two weeks after vaccination.

Johnson & Johnson said in a statement that it has been discussing these reports with the FDA and other health regulators around the world.

The CDC said it will ask its external vaccine expert team to review the issue at an upcoming meeting.

The government stated that the most used vaccine in the United States, produced by Pfizer and Moderna, showed no risk of contracting the disease after inoculation of more than 320 million doses.

Vaccines have traditionally provided extensive protection with little risk, but like other drugs and medical therapies, side effects occasionally occur. The three COVID-19 vaccines used in the United States have been tested in tens of thousands of people, but even such a large study cannot rule out extremely rare side effects.

The CDC and FDA have been monitoring the side effects reports submitted by doctors, drugmakers, and patients to the Federal Vaccine Safety Database.

Guillain-Barre can be caused by a variety of infections, including influenza, cytomegalovirus and Zika virus. But in rare cases, people will develop the disease days or weeks after receiving certain vaccines.

Johnson & Johnson’s vaccines are highly anticipated because of their “disposable” formulations and easy-to-transport cold storage. But in the early days, it was related to another rare risk-blood clots. The company’s output failed to meet expectations due to problems with a factory in Baltimore that helped make lenses.

When the news was released, the demand for COVID vaccine in the United States continued to decline, with only about 430,000 injections per day. The peak 7-day average in April is about 3.5 million.

In under-vaccinated states in the central, western and southern parts of the country, cases are rapidly increasing, and the highly contagious delta variant now dominates.
