Do this could make Covid vaccine less effective, say experts
This major stipulation comes with the Pfizer coronavirus vaccine.
The Covid vaccine will probably mitigate the most pressing problems of the pandemic, but that does not mean that it will not come withproblems of his own. Currently, the Food and Drug Administration of the United States (FDA) is currently reviewing the Pfizer vaccine for emergency use authorization - and while vaccine is a strong efficacy of 95%, effectiveness could flicker in the bad conditions. According to experts, do not keep the covidant vaccine with enough cold could actually make it less effective. Read more about why the vaccine should be kept at the right temperature and for other warnings,You should not do that just after getting a Covid vaccine, expert warns.
The Pfizer vaccine should be kept near -100 degrees Fahrenheit.
Pfizer vaccinemust be kept at a temperature From -70 degrees Celsius (near -100 degrees Fahrenheit) or this may lose its effectiveness. If it seems front, it is even colder than you might think ...colder even than winters in Antarctica. The other Covid Frontrunner Vaccine, Moderna, which should be examined in next week - only must bekept at -20 degrees Celsius, in comparison. So, unlike the Moderna vaccine, Pfizer'scan not be kept in a regular freezerbecause they usually do not reach low temperatures. And for more vaccine problems,These are the only people who should not get the Covid vaccine.
Indeed, the Pfizer formula incorporates a new vaccine technology.
But why should the Pfizer vaccine be kept this cold? According to NPR, the two Covid vaccine fringers use the messenger RNA (mRNA) to helpHuman bodies create a particular coronavirus protein, which can trigger an immune response if Covid enters the body. As it turns out, mRNA vaccine technology is so new that no mRNA vaccine has never been approved by the FDA.
Unfortunately, the mRNA can also be "easily destroyed", which adds complications as vaccines must stabilize this molecule,Margaret Liu, a vaccinal researcher who chairs the Board of Directors of the International Society for Vaccines and specializes in genetic vaccines, said NPR. This is why vaccines are kept at cold temperatures, but we do not know exactly why the levels of Pfizer are so much lower than the modern, because the specific formulations have not been disclosed.
"It just found what their data," said Liu. "If their data show that it's more stable at a certain temperature, that's all." And for more the propagation of coronavirus,Dr. Fauci says that this only thing could spread Covid more than anything that's even.
And while keeping the cold vaccine can be done, experts say it will take a lot of work and money.
Debra Kristensen, a 30-year-old vaccine and supply chain veteran, an international non-profit organization focused on public health, said NPR that the distribution of the vaccine against Pfizer is possible, but it will also "much more expensive and more difficult", especially because it will require the need for specialized freezers.
"I think it can be done," Krisensen said at NPR. "The anti-ebola vaccine, for example, has been successfully used in some African countries and also required this ultra-cold storage of the chain." And for more information up to date,Sign up for our daily newsletter.
But Pfizer tries to facilitate the conservation of the vaccine.
Pfizer, in turn, tried to make this complication as simple as possible. The manufacturer has designed its own packaging forKeep vaccines at cold temperatures with dry ice So that they can be stored for 15 days up to 15 days without these specialized freezers, which can be a useful innovation if the vaccine is approved in the coming days, before distributors can not acquire appropriate freezers. And for more information on vaccine distribution,Here's how to say when you can get the Covid vaccine.
