Original title: Delays in delivery, the new EU vaccination crown is unfavorable
Source: Beijing Commercial Daily
As the epidemic escalated, Europe pinned its hopes on the new corona vaccine, but the shortcomings of the emergency launch have gradually been discovered, such as delayed delivery and even the wrong injection dose. For some people who don’t trust the new corona vaccine, this is certainly unfavorable new evidence. However, when it comes to Europe, there is no better solution than a vaccine to stop the violent momentum of the epidemic.
Last weekend, the new corona vaccine jointly developed by Pfizer and BioNTech was delivered to all EU member states. Older people, medical personnel and politicians in most EU countries have started to vaccinate against the new crown. But at the beginning of the vaccination, chaos arose.
“There are very few vaccines,” complained the governor of Bavaria, Germany. Besides low, some areas of Bavaria even produced “waste”. Thermometers placed in the vaccine transport box showed that the temperature of the vaccine rose to 15 ° C during transport, which exceeded the upper limit of 8 ° C set by the vaccine manufacturer, affecting an injection about 1,000 doses of vaccine.
Compared to the lack of vaccines in Germany, Spain has not even started vaccinating. On 28 local time, the Spanish Ministry of Health declared that Pfizer delayed the delivery of a new batch of new coronavirus vaccines to eight EU countries, including Spain. The Spanish Health Ministry said in a statement that Pfizer had delayed delivery of vaccines to eight EU countries due to “problems during loading and transportation” at its Belgian plant.
It is understood that the EU has currently ordered 2 billion doses of vaccines, but most of them have yet to be approved by the European Medicines Agency (EMA), along with price differences between countries during previous negotiations and problems. cold chain transport, resulting in When the EU received the vaccine, there was a delay in delivery.
Regarding the specific circumstances and reasons for the delay in delivery of the vaccine, a reporter from Beijing Business Daily attempted to contact Pfizer and BioNTech, but as of press time, no response has been received.
Vaccine expert Tao Lina analyzed a reporter for the Beijing Business Daily: “Vaccines must be deep frozen during storage and transportation, so in the actual vaccination process, there will be a lot of resistance.” The Spanish Minister of Health, Salvador Ilia, is receiving media During the interview, it was also stated that the delay in the delivery of the vaccine was related to “temperature control during transport.” Pfizer’s new corona vaccine should be stored in an ultra-low temperature environment of minus 70 ° C. Once out of the ultra-low temperature storage environment, the shelf life of the vaccine is only 5 days.
The chaos did not stop there, an accident occurred on the first day of the large-scale vaccination of the new corona vaccine in Germany. On the 27th, 8 employees in a nursing home in northern Germany received 5 times the dose of the Pfizer vaccine due to human error. 4 people showed flu-like symptoms and were hospitalized for observation.
Regarding the reason for this error, Taolina said that the current vaccines in Europe and the United States are mostly “single vial of multiple doses” vaccines, that is, one vial of vaccine is used by several people or even 10 people. I don’t know if it happened during the operation. If you make a mistake, it may be that the medical staff had some problem in the training process, but in general, this type of error is very “low level”.
The current chaos has deepened some people’s mistrust of the crown’s new vaccine. A poll cited by Reuters showed that the proportion of people willing to get vaccinated in France is around 54%, while that of Italy and Spain is 64%. On the 27th, at a Warsaw hospital that gave the first injection of the new crown vaccine in Poland, only half of the medical staff signed up for vaccination.
This phenomenon is to be expected, in fact, in countries and regions that have already been vaccinated, people suffer from allergies to varying degrees. A doctor from Boston, USA, developed a severe allergic reaction minutes after receiving the new Corona vaccine from Moderna.
There are also allergies in the UK Both cases of allergic reactions have a history of allergy to egg and drugs. Later, the British government issued a statement stating that anyone with a history of vaccines, medications or food allergies should not receive the Pfizer vaccine, and those who had an allergic reaction during the first dose should not receive the second dose.
In this regard, Taorina analyzed that the United States currently uses mRNA (messenger ribonucleic acid) technology for the new corona vaccine, and the protection rate of this vaccine may be 10-20% higher than that of the inactivated vaccine. But it should also be understood that the common adverse reaction rate of mRNA vaccines is also an order of magnitude higher than that of inactivated vaccines. Among the approximately 1 million doses of vaccine that have been vaccinated worldwide, between 7 and 8 cases of allergies are known to occur and the proportion of vaccines is very high.
“The currently used US vaccine is only licensed for emergency use. Phase III clinical trials are still in progress and have not been approved for commercialization. For a new vaccine for emergency use, it can be said that such a lack maturity in the details is relatively common. At the same time, further adjustments are urgently needed in accordance with the situation, “said Tao Lina frankly.
However, for Europe, vaccines are already the only hope. According to data from Johns Hopkins University in the United States, the number of confirmed cases of new corona in 27 EU countries has reached close to 15 million, and the death toll has exceeded 353,000.
