An investigation remains underway after two men died within days of receiving their second dose of the Moderna Covid-19 vaccine in Japan.
It’s understood that the men, aged in their 30s, were administered vaccine doses from one of the three suspended batches of the Moderna vaccine.
The doses were suspended due to the presence of a contaminant in certain doses.
Although the men’s causes of death are still being investigated by Takeda, Japan has halted 1.63 million doses of the Moderna vaccine as a precaution.
Both Takeda Pharmaceuticals and Moderna stated, “At this time, we do not have any evidence that these deaths are caused by the Moderna Covid-19 vaccine,”.
The statement added, “It is important to conduct a formal investigation to determine whether there is any connection.”
The Japanese government stated that there were no efficacy or safety issues identified and that the three batches were only suspended as a precaution.
While cautioning against drawing a connection between the vaccination and fatalities that were reported on Saturday, the infection control manager at St. Luke’s International Hospital in Tokyo Fumie Sakamoto told Reuters, “There may only be a temporal relationship between vaccination and death,”.
The contaminants that were found in the vaccine vials are believed to be metallic particles, according to public broadcaster NHK, who were citing health ministry sources.
In regards to Saturday’s fatalities, the health ministry told reporters that each man developed a fever following their second dose and died two days later, however, they added that there is no evidence to support the idea that their shots were contaminated.
