Covid-19 Vaccine Johnson & Johnson can be associated with an increased risk of Guillain-Barré syndrome, a rare neurological condition but potentially serious, said Federal Official Monday.
Food and drug administration has added a warning about potential side effects on fact sheets about vaccines.
The risk seems very small.
So far, there are 100 reports of syndrome in people who have received Johnson & Johnson vaccines.
Nearly 13 million vaccine doses have been given in the United States.
Here are the answers to some general questions about the syndrome and the connection to vaccination.
What is Guillain-barré syndrome? Guillain-Barré is a rare condition where the immune system attacks nerve cells.
This can cause muscle weakness and paralysis.
Although the symptoms often pass in a few weeks, in some cases, the conditions can cause permanent nerve damage.
In the United States, there are usually 3,000 to 6,000 cases of syndrome per year, according to the Center for Disease Control and Prevention.
It’s most common in adults more than 50.
Causes of precision syndrome is unknown, but in many cases conditions follow other diseases or infections, such as flu.
It has also been reported to people with Covid-19.
What is the connection with vaccination? This is not the first vaccine associated with Guillain-Barré, even though the risk seems small.
The large swine flu vaccination campaign in 1976 caused small uptick in the incidence of syndrome; This vaccine causes around one extra guillain-barré case for every 100,000 people vaccinated.
Seasonal flu shots are associated with approximately one additional case for every 1 million vaccines given.
“I think the data is quite interesting so the flu vaccine causes the Guillain-Barré syndrome, but it is a very small risk,” said Daniel Salmon, Director of the Institute for the safety of the vaccine at the University of Johns Hopkins.
Shingrix shirting vaccine can also increase the risk of these conditions.
Not entirely clear why some vaccines can cause guillain-barré.
“We don’t really understand the biological mechanism,” Salmon said.
“It’s extraordinary frustration.” What do we know about the relationship with the Covid-19 vaccine? One hundred syndrome reports after vaccination with Johnson & Johnson Shot has been submitted to the reporting system of the events of the Federal Vaccine (VAER), officials said Monday.
From them, 95 cases produce inpatients, and one fatal.
This syndrome is generally reported about two weeks after vaccination, especially in men, many of them are 50 or more, officials said.
There is not enough evidence to determine that this vaccine causes conditions, but the FDA will continue to monitor the situation, the institution recorded in a statement.
There is no data to suggest links between Covid conditions and vaccines made by Pfizer-Biontech or by Modera, which rely on different technologies, the FDA said.
What signs and symptoms should I pay attention to? This syndrome is most likely to appear in 42 days of vaccination, FDA records on the revised fact sheet for patients.
You should consult a doctor if you start experiencing weakness or tingling in your arms and legs, double vision or difficulty walking, talking, chewing, swallowing, or controlling the bladder or your intestine.
Should I still get a Covid-19 vaccine? If the link between vaccines and guillain-barré is real, it seems far exceeding the risk of Covid-19, the experts said.
In the United States, almost all hospitalizations and deaths from Covid-19 are happening to those who are not vaccinated, the word CDC in a statement.
The agency recommends that everyone aged 12 or more vaccinated.
“Everything has a risk,” Salmon said.
“And the key to decision making is to optimize the benefits and reduce risk.” He added, “Covid is a fairly evil illness that killed 600,000 people.”
