As Covid vaccination advances around the world, researchers continue to work on new ways to deliver the vaccine. Spray, pill, powdered vaccine … We take stock of current research!
a vaccine against the Covid in the form of pill, spray or in powder… This is the research currently underway in several laboratories around the world by several teams of scientists, working on other means of administering the various vaccines already available on the market.
Three modes of administration under study that our colleagues from the BBC noted, relayed by Ouest France, indicating that the studies were in progress and were progressing rather well. And to give a first example with a vaccine by spray – or more precisely by inhalation – currently under study in Sweden, “as big as a box of matches“. This one, imagined by Iconovo and the research start-up ISR, would take the form of a powder and would use virus proteins (therefore viral vector).
A technique also under study at Pfizer, and which would allow the vaccine to be stored at temperatures of up to 40 degrees. In France and around the world, spray technology is also arousing a lot of interest, to the point that clinical trials have been launched on the issue.
Covid: a nasal spray vaccine in development
Will the fight against Covid go through the nasal spray? Many researchers are working hard to develop a vaccine using this method, such as researchers from the University of Tours and INRAE who could develop a vaccine using this technology within a few weeks. month.

Covid: the nasal spray vaccine from Inrae and the University of Tours soon to be marketed?
Soon a vaccine in nasal spray really effective against the Covid? In any case, this is what researchers from Inrae and the University of Tours are saying, who filed a patent on Thursday, September 9, 2021 for a candidate vaccine by nasal administration. A vaccine candidate that has shown promising results in animals, according to researchers. A nasal spray that could be released in 2023. [Lire la suite]
Pfizer and BioNtech prepare powdered vaccines to overcome cold stress
Pfizer and BioNtech have been announcing it for a few days now, they would have vaccines that are more than 95% effective against the coronavirus! The only downside is that these two products must be stored at -80 ° C, which poses some logistical concerns. The two laboratories are therefore working on a powder version to remedy the problem.

Another object of study: the pill vaccine. A product that would be just as effective as an injection, as reported by our colleagues from the Jerusalem Post who explains that the start-up Oravax Medical had just launched a first clinical test On the question. A common technique for many drugs, but the efficacy of which is not known for the vaccine.
Covid: Pfizer unveils its first oral treatment against the virus
Coming soon to a treatment against Covid in the form of a pill? The Pfizer laboratory has announced that it has started clinical trials around a drug of this type, in two establishments of the group, and potentially marketed by the end of the year if the results are conclusive, after validation by the health authorities.
