Experts have said that the new Covid-19 vaccine, of which the American company “Pfizer” announced it was 90% successful during the trial phase, could turn into a nightmare during its distribution process, a due to the extremely low temperatures in which it must be stored.
And the potential coronavirus vaccine must be kept at minus 70 or below to achieve the desired efficacy.
“Your usual pharmacy or doctor’s office is unlikely to be able to administer this vaccine,” Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University Medical Center, told the New York Post.
He added that the vaccine poses unique challenges because it is not protein-dependent like most other vaccinations.
He explained that proteins are largely stable and this is most vaccines. He continued: “It was produced so that it could be stored in the refrigerator.”
Schaffner noted that the Pfizer vaccine is “completely different” because it is made up of genetic materials, known as mRNA (messenger RNA), to activate the immune system against the virus.
He stressed that if not kept at the correct temperature, the vaccine component “begins to collapse and rotate in such a way that it does not become effective.”
“The vaccine is very fragile.” The MRNA starts to break down very quickly at warmer temperatures, so it has to be kept at extremely low temperatures. “
Schaffner said the complex storage requirements mean healthcare workers will need to be specially trained to quickly and safely eject their vials.
And for people trying to go out and get vaccinated, it’s probably not as simple as going to the clinic.
He added: “Many people will have to queue to get the vaccine, or it will be lost. We will not be able to get the vaccine to the person. We will have to get all people to the vaccine.”
Dr Sandra Kish, an infectious disease specialist at West Med Medical Group, said it becomes more difficult when other obstacles are taken into account, including the fact that the group has to return to the second dose after three weeks.
“When you think about hiring and social distancing and how you can’t cram people into the waiting room, it becomes very difficult to think about how it would work,” he added.
He noted that even without the obstacles of storing the vaccine, it would be an unprecedented challenge to vaccinate enough people to gain herd immunity in the country.
And he continued: “If you’re looking for the 60 or 70 percent of the population that needs vaccinations, what does it look like realistically?”
And he said: “Even if all pharmacies are fully operational, every hospital is running at full capacity.” [و] In any doctor’s office, it is still difficult to obtain the number of people who have been vaccinated in a short period of time. “
But she indicated that she is confident that the makers of the major candidate vaccines have contemplated many of these obstacles.
“They are looking into what the actual transport and configuration entails, because if that isn’t logistically feasible, it seems almost pointless,” he added.
