Washington, Dec 13 (Prensa Latina) The results of studies by researchers at Yale University have demonstrated how intranasal vaccination can provide broad-based protection against heterologous respiratory viruses in mice, while systemic immunization, which used an injection to elicit body-wide protection, does not.
The emergence of COVID-19 variants such as delta and omicron have sent scientists scrambling to determine whether existing vaccinations and boosters are still effective against new strains of SARS-Cov-2.
In a new study by Yale's Akiko Iwasaki, the Waldemar Von Zedtwitz Professor of Immunobiology, it was found that intranasal vaccination provided broad-based protection against heterologous respiratory viruses in mice.
