Probiotics show efficacy protecting mice infected with flu. More here: [1], [2], [3], [4], [5], [6].
Probiotics are also effective in elevating seroconversion of influenza vaccines.
Probiotics protect children from influenza as well.
Probiotics reduce cough incidence by 41-62%, rhinorrhea incidence by 28-58%, fever incidence by 53-72%. Children receiving probiotics had significant reductions in days absent from group child care, by 27-31%, and antibiotic use incidence was reduced by 68-84% compared to placebo.
Probiotics may help in the treatment of cervical dysplasia.
Vitamins C, A, E, vitamin D, group B vitamins, green tea extract , turmeric and healthy vaginal flora significantly reduce the risk of dysplasia.
That is, if you do not smoke, do not take oral contraceptives, eat well, do not destroy vaginal microflora with douching chemicals, get pap-smears once in a while, then the risk of cervical cancer, which is already very low, is reduced to almost zero without any vaccinations.
