The United States will temporarily stop using the corona vaccine from pharmaceutical company Janssen,

The New York Times


Tuesday, based on government



After approximately seven million injections of the vaccine, six women developed a rare combination of blood clots and a low platelet count.

Whether these complaints are actually caused by the vaccine is still being investigated.

So far this is about one suspicious report per 1.17 million injections.

All six reporters with the blood clots are women between the ages of 18 and 48.

One of the women has died of the disease and a second woman is in a critical condition, officials told the newspaper.

The American Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) will work together to find out whether the health problems are really caused by the vaccine.

Subsequently, it will be determined whether the vaccine can be used again for all adults, or whether, for example, certain groups should be excluded.

It is still unclear when more will be known.

In any case, the Janssen vaccine will no longer be used in federal (national) vaccination locations.

In addition, there are injection sites that are run by the American states themselves.

The government will call on the states to temporarily stop using the corona vaccine from Leiden there, too, but those states may ultimately decide for themselves.

There have been reports of similar complaints in the US that may have been caused by the Janssen vaccine.

Research was also done then, but no connection was found.

Such health complaints can also be a coincidence: if millions of injections are taken, it can sometimes happen that someone 'accidentally' becomes ill shortly after his injection.

A link may be found in this new research.

Similar complaints to AstraZeneca vaccine

The European Medicines Agency (EMA) also announced last week that it is likely that this clinical picture is a (very rare) side effect of the AstraZeneca vaccine.

But that is a different manufacturer and a different way of vaccine production.

Johnson & Johnson, Janssen's parent company, says in a response that it is aware of the cases.

"We are aware that these side effects have been reported with COVID-19 vaccines. Currently, however, there is no clear causal relationship between these rare events and the Janssen COVID-19 vaccine."

The Janssen vaccine has so far been used worldwide only in the United States.

The first delivery from Janssen arrived in the Netherlands on Monday.

It must be administered for the first time in the Netherlands later this month.
