Effervescent tablets "contain egg yolk antibodies specific for the virus's membrane-bound proteins, supplemented with vitamin C and other minerals to boost the immune system," explains a university textbook on the research project.
"It is a method that can be used by the whole population and not only by patients at risk, and has the advantage of being non-invasive compared to traditional vaccination," said the research team.
The "secret" of the tablets, made with vitamin C and various minerals, is in the antibodies taken from the egg yolks of the chickens.
Without the contraindications of vaccines that have to be reformulated every year and without the invasive needle, the tablets developed by the University of Aveiro project, which hopes to obtain funding, is a means "capable of revolutionizing the fight against influenza."
Igy antibodies (so-called key ingredients of effervescent tablets) are produced exclusively by birds, being concentrated in the egg yolks.
