A potential vaccine against the new coronavirus has proven successful in mice -- and researchers say it could be rapidly made and distributed if it proves effective in humans.
EBioMedicine.
What's new is the delivery system, explained Falo, a professor at Pitt's School of Medicine. The vaccine would be given using a tiny patch of"microneedles" that are made entirely of the viral proteins and sugar. The needles simply dissolve into the skin, he said. A vaccine that needs no refrigeration would be easier to distribute on a mass scale, explained Lee, a professor of health policy management at City University of New York.
Of course, the practicality of any COVID-19 vaccine only matters if it actually works, Lee pointed out. And it will be some time before any of the candidates under development can be proven safe and effective.Numerous companies and academic research teams are racing to develop a vaccine against the novel coronavirus, and they're taking a range of approaches.
The first phase of the trial -- which is looking at safety and dosing -- launched in what NIAID director Dr. Anthony Fauci called"record speed." But he has also cautioned it could be 18 months before any vaccine is available, and some infectious disease experts have doubted it will happen that soon. The animals given the new vaccine have not yet been followed long-term. But mice that received a previous, similar MERS vaccine produced enough antibodies to neutralize that virus for at least a year; the antibody levels with this experimental vaccine are following a similar pattern, the Pitt researchers said.
