The Korea Illness Management and Prevention Company instructed reporters in a closed-door briefing that as extra nations in Europe and elsewhere shelve the vaccine over unconfirmed blood clot fears, the company “might take precautionary steps.”
The Korean nationwide well being company mentioned it was “intently monitoring” the AstraZeneca suspensions in European nations, and that it might pause the vaccine’s rollout right here relying on the outcomes of the European Medicines Company’s investigations slated for announcement Thursday.
The European Union regulator mentioned in a web-based assertion Monday that it could be calling a rare assembly this week to “conclude on the knowledge gathered (over reviews of blood clotting occasions in AstraZeneca vaccine recipients) and any additional actions that will should be taken.”
Korea “might undertake a cautious strategy” to the AstraZeneca vaccine, the KDCA instructed reporters the next day on Tuesday.
“However from what we all know to this point, the vaccine ought to proceed for use,” mentioned the company. “The AstraZeneca COVID-19 photographs administered in Korea are produced at an area plant, so they’re totally different from the batches utilized in Europe.”
The company mentioned there’s “no proof the AstraZeneca vaccine causes blood clots,” and that the drug regulation authorities discovered “no such points over the course of the rigorous testing earlier than granting approval.”
On Wednesday, Korea additionally confirmed a suspected case of deadly blood clotting in an individual inoculated with an AstraZeneca shot. Though postmortem examinations are nonetheless underway, no hyperlink to the vaccine is suspected, based on Jung Eun-kyeong, the Korea Illness Management and Prevention Company commissioner.
Jung instructed a parliamentary committee for well being and welfare Wednesday morning that one of many suspected antagonistic occasions in Korea with a deadly final result had concerned blood clots.
The girl who had blood clots was in her early 60s and chronically sick, based on the KDCA temporary later the identical day. She was given her first AstraZeneca vaccine dose on Feb. 26, and died a few week afterward March 6.
Prior up to now, the KDCA had refused to say whether or not there had been any reviews of potential antagonistic occasions associated to blood clots regardless of press inquiries. The case Jung talked about is at the least three days outdated, as there have been no new reviews of deaths amongst vaccine recipients since Sunday.
As of Tuesday at midnight, 587,996 individuals in Korea acquired the primary of two doses of the AstraZeneca vaccine. About 1.5 p.c of them, or 8,876, reported experiencing potential antagonistic occasions. The overwhelming majority, or 8,777, had delicate, recognized unintended effects corresponding to injection website discomfort and physique aches that lasted only a few days.
The remaining have been extra severe occasions together with 75 instances of anaphylaxis-like reactions, one seizure, seven intensive care unit hospitalizations and 16 deaths. Investigations up to now revealed not one of the reported occasions have been associated to the vaccines.
Specialists say there’s not sufficient knowledge but to justify suspending the usage of the AstraZeneca vaccine.
The Worldwide Vaccine Institute’s Director Common Dr. Jerome Kim mentioned from the angle of ordinary unintended effects, the AstraZeneca vaccine was “not that totally different” from different vaccines.
“The EMA and WHO have continued to say that the AstraZeneca vaccine is protected, as had the UK and its regulators. And they’re in fact rigorously investigating these occasions,” he mentioned.
He mentioned the regulators have been investigating the “potential variations in vaccine unintended effects primarily based on the manufacturing ‘batch.’”
He steered the European nations’ selections to cease administering the vaccine might have stemmed from causes apart from science: “I believe that the response of European nations can also replicate political issues inside the nations and considerations concerning the vaccine’s acceptability.”
Kim mentioned it was “unlikely” that the blood clot concern was missed through the giant Section 3 trials that had already been accomplished, and that extra assurance ought to come from one other one happening within the US that features extra volunteers over 65 years outdated.
“There weren’t that many aged within the authentic AstraZeneca trial. That isn’t the case within the US trial. Hopefully the US Section 3 trial will assist assist the prevailing efficacy and security knowledge,” he mentioned.
To quell public anxiousness across the vaccine public well being authorities ought to “talk the outcomes of their findings promptly and reply questions,” he mentioned.
“If the info assist the security and continued use of AstraZeneca vaccine then they need to additionally state that clearly,” he mentioned.

Preventive medication professor Dr. Jung Jae-hun of Gachon College mentioned the blood clot incidents in vaccinated individuals have been “statistically insignificant.” “The reviews of blood clots in individuals given AstraZeneca vaccine aren’t essentially higher than the identical well being points occurring naturally in a basic inhabitants,” he mentioned.
Virology professor Dr. Paik Quickly-young of Catholic College of Korea mentioned he “extremely doubts” the EMA would discover something to retract its earlier assertion that the vaccinations are answerable for the “very uncommon” blood clots. “The controversy surrounding the vaccine is uncalled for,” he mentioned.
