Clinical trials for children of a novel coronavirus infection (Corona 19) vaccine jointly developed by British pharmaceutical company AstraZeneca and Oxford University in the UK have been temporarily suspended.

The British public broadcaster BBC said on the 6th (local time) that child clinical trials were halted while investigating the relationship between adult vaccination with the AstraZeneca vaccine and the occurrence of blood clots. AstraZeneca has been conducting clinical trials to confirm the efficacy of the vaccine in about 300 children aged 6-17 years since last February. UK SkyNews reports that Andrew Pollard, a professor at Oxford University, said, “There are no safety concerns in the child clinical trial itself, but we are waiting for more information regarding the UK Pharmaceutical and Health Care Products Regulatory Authority (MHRA)’s investigation of adult thrombosis incidences before additional vaccinations are given.” It was reported that it was revealed.

The cessation of clinical trials of the AstraZeneca vaccine in children was due to suspicion that the vaccine might be related to blood clots in young people. It was reported the day before that the British government was considering other vaccinations for people under the age of 30 over blood clots concerns. On the same day, a high-ranking official from the European Medicines Agency (EMA) said to the Italian media that the AstraZeneca vaccine was causally related to the rare reported specific thrombosis, and the suspicion is spreading.

However, the British authorities still have to believe in vaccines. British Prime Minister Boris Johnson visited the AstraZeneca vaccine factory on the same day and said, “Follow the opinion of MHRA” regarding blood clots concerns, and “their advice is to keep vaccinations.” The World Health Organization (WHO) also adhered to the previous assessment that the benefits of the AstraZeneca vaccine outweigh the risks. EMA is still reviewing the relationship between vaccines and thrombosis, and a briefing is due to close on the 7th or 8th.
