Needle-free nano-vaccine, cheap to produce, requires no refrigeration and is administered as nasal spray, making it accessible to developing nations.y
A pair of scientists from Israel and Portugal have developed an inexpensive and effective new nano-vaccine against Covid-19, which can be stored at room temperature and administered as a nasal spray.
The breakthrough vaccine trains the immune system against all common Covid-19 variants with the same efficiency as existing vaccines.
But it does not require an injection or a cold supply chain and cold storage, making it ideal for vaccinating at-risk populations in developing countries and in remote regions.
In addition, the scientists believe it paves the way to the development of simpler, more effective, and less expensive vaccines in the future.
Prof. Ronit Satchi-Fainaro from Tel Aviv University’s Faculty of Medical and Health Sciences developed the vaccine in collaboration with Prof. Helena Florindo at the University of Lisbon.
“The new nano-vaccine’s development was inspired by a decade of research on cancer vaccines,” said Satchi-Fainaro. “When the Covid-19 pandemic began, we set a new goal: training our cancer platform to identify and target the coronavirus.”
Satchi-Fainaro said the researchers did not rely on full protein expression via mRNA, unlike the Moderna and Pfizer Covid vaccines.
“Instead, using our computational bioinformatics tools, we identified two short and simple amino acid sequences in the virus’s protein, then synthesized them, and encapsulated them in nanoparticles.”
“Our nano-vaccine offers a significant advantage over existing vaccines because it is needle-free and administered as a nasal spray,” said Satchi-Fainaro.
“This eliminates the need for skilled personnel such as nurses and technicians to administer injections, while also reducing risks of contamination and sharps [biohazardous] waste. Anyone can use a nasal spray, with no prior training.”
Stored as powder, as effective as Pfizer
Another major advantage of the nano-vaccine is its minimal storage requirements.
Moderna’s sensitive mRNA-based vaccine must be kept at -20°C and Pfizer’s at -70°C, generating great logistic and technological challenges, such as shipping in special aircraft and ultra-cold storage from the factory to the vaccination station.
The synthetic nanoparticles are far more durable and can be stored as a powder at room temperature.
“There’s no need for freezing or special handling,” said Satchi-Fainaro. “You just mix the powder with saline to create the spray. For testing purposes [as part of the EU’s ISIDORe Integrated Services for Infectious Disease Outbreak Research feasibility program] we shipped the powder at room temperature to the INSERM infectious diseases lab in France. Their tests showed that our nano-vaccine is at least as effective as Pfizer’s vaccine.”
Aside from its value to developing countries, Satchi-Fainaro said the plug-and-play technology provides a platform enabling scientists to synthesize more effective and affordable vaccines for future pandemics.
“[The technology] can train the immune system to fight cancer or infectious diseases like Covid-19. We are currently expanding its use to target a range of additional diseases, enabling the rapid development of relevant new vaccines when needed,” she said.
The research has received grants from the Israel Innovation Authority and Merck under the Nofar program, as well as funding from Spain’s La Caixa Foundation Impulse as an accelerated program, and support from the ISIDORe feasibility program.
It is also part of a broader vaccine platform development program at Satchi-Fainaro’s lab, supported by a European Research Council Advanced Grant.
“The breakthrough vaccine trains the immune system against all common Covid-19 variants with the same efficiency as existing vaccines.”
LOL
Not exactly a powerful marketing slogan.
Give it to Bill Gates!
They can KMA with their nano tech.
So it doesn't work either.
This hyper fixation on what is now a fairly minor virus is creepy. If this was really doable why don't we have a vax for the common cold? Or one that works on all flu variants instead of 10% (at best)?
Still not getting it.
with the same efficiency as existing vaccines............SRRT..........
In other words, with the same efficiency as powdered sugar.
Horse paste works great except for a craving for carrots and sugar cubes.
Still no.
Or a Timber Rattler.
Hey, they said “efficiency,” not “efficacy.”
Are the nano-particles as unnecessarily invasive, more unnecessarily invasive or less unnecessrily invasive than the mRNA sequences in the other Covid vaccines??
This one couple I know have had every vaccine and they keep getting covid. They literally avoid gatherings because they are scared of getting it again. She is a nurse and and when we first met three years ago she was lecturing me for refusing to get jabbed. I told her if I get covid I would just get some Ivermectin ect... She laughed at me and started making fun of the horse paste. I don’t know how many rounds of shots they have had since then, but I still have yet to get covid and they can’t meet us for dinner because they are too scared to go out.
They’re bound and determined they are gonna get that shit in everybody’s body one way or another
Why no protection against corona virus 1 - coronavirus 18?
Or SARS 1?
We’re all about to get crop dusted!-(
