If side effects are detected in vaccinated people, the manufacturer suspends its use in order to conduct additional tests. On Tuesday, April 13, the infectious disease doctor Evgeny Timakov told Izvestia, commenting on the decision of Johnson & Johnson to postpone the use of its COVID-19 vaccine.
“If vaccinated people develop side effects, the vaccine company, after receiving data on thrombosis or other complications, suspends its use. The suspension is for the purpose of additional testing. It is important to understand whether the vaccine is dangerous or not, ”Timakov said.
He also added that after that additional recommendations will be developed to prevent complications that may arise during vaccination.
Earlier in the day, White House COVID-19 Coordinator Jeff Zints said that the temporary cessation of Johnson & Johnson’s vaccine use would not have a significant impact on the vaccination plan for US residents.
On April 13, the US Food and Drug Administration (FDA) and the Center for Disease Control and Dissemination (CDC) recommended that Johnson & Johnson’s coronavirus vaccination be suspended.
The departments said that the decision was made due to precautions. The media have repeatedly published information that after vaccination, cases of blood clots were recorded. Since then, the company has postponed the use of its coronavirus vaccine in European countries.
On April 9, in the United States, three Johnson & Johnson coronavirus vaccination centers located in North Carolina were temporarily closed due to the detection of side effects of 26 people after using the vaccine.
After using the drug, four people were admitted to hospitals for further examination. The US Centers for Disease Control and Prevention has described fainting as not uncommon after vaccination.
Prior to that, on March 17, the World Health Organization’s (WHO) strategic advisory group on immunization recommended careful monitoring of potential side effects from Johnson & Johnson’s vaccine, including allergic reactions and bleeding problems.
