- In the United States, sinus nerve thrombosis occurred in six cases after vaccination with the active ingredient from Johnson & Johnson.
- Authorities now recommend suspending the vaccine.
- The vaccine manufacturer also now wants to postpone its distribution to Europe because of potential side effects.
American pharmaceutical company Johnson & Johnson postpones offering its corona vaccine due to severe side effects Europe. “We decided to get started Vaccine Postponed in Europe, “the panel said Tuesday.
Previously, there was a break from U.S. health officials Vaccines The J&J vaccine is recommended after sinus vein thrombosis is diagnosed in six people in the country.
The cases will now be investigated very closely. Until a decision is made, the recommended precaution is to suspend vaccinations with Johnson & Johnson.
Johnson & Johnson aims to supply 55 million vaccines to EU countries
So far, more than 6.8 million vaccines have been released by the end of February United States Was approved, of which only one dose was taken, which was injected into the United States.
Six cases of sinus nerve thrombosis 6 to 13 days later are currently being investigated. In all three cases, thrombocytopenia, or a deficiency of platelets, was reported. The victims ranged in age from 18 to 48 years.
The European Pharmaceuticals Association (EMA) announced last week that it was examining thrombosis cases after being vaccinated by Johnson & Johnson. There were four severe cases of blood clots, one of which died. The authority insisted that an association with the US manufacturer’s vaccine had not yet been established.
It was Monday Johnson & Johnson with delivery He launched his vaccine, which was approved in EU countries in March. The Brussels Authority first expects 55 million doses of the vaccine by the end of June. A good 10 million cans should go to Germany.
The cause of thrombosis after corona vaccination is not yet clear
In March, there were vaccines with the manufacturer’s product in Germany Astrogeneka was temporarily suspended, Accordingly Paul Earlich Institute (PEI) recommended a related procedure.
Some other European countries have also stopped vaccinating for now. There was a significant increase in the background of blood platelets (thrombocytopenia) and sinus nerve thrombosis in relation to bleeding shortly after vaccination.
It is not yet clear why this serious side effect occurs in some people who have been vaccinated. Griffswald researcher Andreas Grencher blames the appearance of certain antibodies to thrombosis.
Because there is something in the body of the victim, they are easily susceptible to the development of these special antibodies. It is not yet clear what that is, he said recently.
Vaccines from Johnson & Johnson & Astrogeneneka are called vector-based vaccines. They use a harmless virus to transmit genetic information from the corona virus to the body. With the help of this information, a virus protein develops in the body of the vaccinated person, and precisely the spike protein on the surface Corona virus.
Carsten Watzle, general secretary of the German Immune Society, recently suggested on Twitter that adenoviruses used in both vaccines cause side effects. He pointed out that there are not enough alternative MRNA vaccines for people under 60 years of age. (dpa / thp)
Corona varieties, current vaccines against which are less effective or no longer effective, may also emerge in Germany, the researchers said.
