Covid-19 roundup: Human error to blame for steel found in Moderna vials; Flu and Covid-19 shots safe to be taken together — study
A month after more than 1.6 million doses of Moderna’s Covid-19 vaccines were suspended due to stainless steel found in the vials, Takeda says that human error was the reason for the contamination.
A Spanish manufacturer noticed contamination in July, Reuters reported, but supplies were permitted to be shipped to Japan anyway. Three batches were suspended for use in Japan, and Moderna collaborated with Takeda and the Spanish manufacturer Rovi to investigate.
A new report says that the human error was due to misjudging a required 1 mm gap between the star-wheel and the stopper of machinery. Five lots manufactured at Rovi between June 27 and July were investigated. Stainless steel was found inside of 39 vials in the first three lots, and a fourth and fifth lot failed inspection and were held back by Rovi.
Two men in their 30s died in August just days after receiving the second dose of their shot, which was a part of the three lots that will be recalled. The cause of death is being investigated right now.
Despite more than a million doses being held from distribution, Japan’s vaccine efforts have consistently held up. Prime minister Yoshihide Suga has said that he was aiming for 60% of the population to be vaccinated by the end of September. On Sept. 30, 60.6% of Japan’s people had received both shots, while 70.8% received at least one shot.
Flu and Covid-19 shots safe to be taken together – study
A UK study says it’s safe to receive both the Covid-19 vaccine and a flu shot at the same time, Reuters reported.
The study from the University of Bristol of 679 volunteers at 12 sites across England and Wales found that side effects were mild to moderate and that the immune response was not negatively impacted for protection against either illness.
Shots were given to participants on the same day in different arms. When asked, 87% of participants said that they would be willing to have the shots in the same day to save time planning appointments.
The full results will be published in the Lancet.
