A research group from Wuhan Institute of Virology, Chinese Academy of Sciences, on Saturday announced they have developed a new type of flu vaccine using nano-technology.
Cui Zongqiang, leader of the research group said the intranasal nano-vaccine can target broad-spectrum flu viruses and induces robust immune responses.
“In our study, an intranasal nano-vaccine worked well against infections of H1N1 and H9N2 virus in mice.
“The results suggest that the 3M2e-rHF nanoparticle is a promising, needle-free, intranasally administered, cross-protective influenza vaccine,’’ Cui said.
Across China, measures have been taken contain the winter flu outbreak.
Experts said flu infections this winter are 71 per cent above the average for the same period in the previous three years, with child cases rising sharply.
Flu outbreaks have been also reported worldwide including the U.S., Canada, Britain, Italy, North Africa, Japan, and the Republic of Korea since winter 2017.
