In an interview, he said one of the main advantages of vaccine nasal is its ability to be refrigerated at 2-4 degrees Celsius, rather than the very low temperatures for Pfizer and Moderna.

“Much, much cheaper to manufacture vaccine this is compared to vaccine mRNA by Pfizer and Moderna,” Palese said. Phases one and two trials are currently being facilitated in parallel due to the urgency of the pandemic.

People from five countries are involved in the trial and preliminary data are expected this July.

“It works well in animals, we have fantastic and interesting research on hamsters and mice, but clearly mice and hamsters are not humans,” Palese said.

On the other hand, scientists at Washington University in St. Louis are also working on vaccine Covid-19 nose. The research team, led by viral immunologist Michael Diamond and oncologist David Curial, found that mice that received a single dose of vaccine through the nose is fully protected from SARS-CoV-2. But the rat that received vaccine the same by injection is only partially protected.
