According to the new study vaccine for novel coronavirus generates immunity in mice.
The study noted that when tested in mice, the potential vaccine generated a surge of antibodies against the coronavirus, SARS-CoV-2, within two weeks of delivering it.
We are very close in developing a vaccine against coronavirus.
They said it works the same way as current flu shots.
In the study, the researchers also used a novel approach to deliver the drug, called a microneedle array, to increase potency.
They said this array is a fingertip-sized patch of 400 tiny needles that delivers the spike protein pieces into the skin, where the immune reaction is strongest.
According to the scientists, the patch goes on like a Band-Aid and then the needles, made entirely of sugar and the protein pieces, simply dissolve into the skin.
They developed this to build on the original scratch method used to deliver the smallpox vaccine to the skin, but as a high-tech version that is more efficient and reproducible patient to patient,” said co-senior author Louis Falo from the University of Pittsburgh.
And it’s actually pretty painless — it feels kind of like Velcro.
Once manufactured, they believe the vaccine can sit at room temperature until it’s needed, eliminating the need for refrigeration during transport or storage.
mice who got their vaccine produced a sufficient level of antibodies to neutralize the virus for at least a year.
They said Testing in patients would typically require at least a year and probably longer.
The scientists believe based on recently announced revisions to the normal processes that they may be able to advance this faster.
