A resident of the Lithuanian city of Marijampole was accidentally injected with five doses of the Pfizer coronavirus vaccine at once, the 15min.lt portal reports, citing the director of the local hospital, Mantas Chesnu.

He stated that "nothing bad happened" to the woman. The clinic also consulted with Pfizer. It is noted that the woman only complains of severe pain at the injection site. “If it were anything fatal or harmful to health, the medicine would be packaged differently, given the risk of human error,” the clinic said.

This is not the first time that doctors are mistaken with the dosage of the vaccine, says Sergey Shulyak, CEO of the DSM Group analytical agency.

Sergey Shulyak General Director of the DSM Group analytical agency “Both one dose and five are poured into bottles. But this is all indicated, of course, on the packaging, directly on the bottle, and therefore when a nurse or doctor makes a vaccine, they must carefully study what is written on the bottle. Unfortunately, there are cases when a five-fold dose of the vaccine is administered. Prior to that, in Germany, a nurse in a nursing home had vaccinated the elderly in a five-fold dose - it's good that everything ended well. Sputnik V also has such a dosage in a bottle. Therefore, in Moscow, there were cases when people not from those categories who were allowed to be vaccinated, signed up and used the fact that polyclinics could not send them home, because they defrosted a five-dose vial, they need to be vaccinated with five doses."

An overdose of the coronavirus vaccine cannot be harmed, says immunologist Vladimir Bolibok.

- An overdose of the vaccine, if we are talking about the Pfizer vaccine, matrix, it does not threaten anything special, because the amount of vaccine material that can contact human cells is limited not so much by the amount in the vaccine itself, in the packaging itself, but by the capacity, relatively speaking, cells that can absorb it. Since the vaccine is in a certain environment, in a buffer, this buffer itself can cause some painful sensations. The pH of this buffer is likely to be different from that of the human body.

- And if, for example, we are talking about our Sputnik V vaccine?

- Also, nothing terrible will happen, since this is a vector vaccine, vectors bind exclusively to epithelial cells, it is even more favorable for a person than to inject a matrix vaccine, to do an overdose. Those vaccines that are now on the way - EpiVacCorona and KoviVac - as far as I understand, will have one dose in one ampoule.

On Friday, the European Medicines Agency will decide on the admission of another coronavirus vaccine to the European market. This is a drug developed by the pharmaceutical company AstraZenec in cooperation with scientists from the University of Oxford. Like Sputnik V, it is a vector vaccine. Experts at the German Permanent Vaccination Commission at the Robert Koch Institute believe that the AstraZenec vaccine is not suitable for people over 64 years old. The pharmaceutical company denies this.
