"New data will be presented to the Advisory Committee on Immunization Practices on Thursday that appears to show that the incidence of blood clots in people vaccinated by Johnson & Johnson has increased since April, although the problem is still rare," the publication said. ...

From December 2020 to August 31, 2021, there were six deaths among people vaccinated with the J&J vaccine with blood clots, according to the newspaper. 

A total of 50 cases of blood clots have been identified after vaccination with this drug.

On September 29, the Slovenian authorities decided to suspend the use of the Johnson & Johnson vaccine.

The head of the Ministry of Health of Slovenia, Janez Poklukar, noted that the decision is related to the death of a 20-year-old girl less than two weeks after the vaccination.
