Prevention of influenza episodes with colostrum compared with vaccination in healthy and at-risk patients with cardiovascular disease: Epidemiological study in San Valentino, Pescara, Italy.
The effectiveness of 2-month colostrum intake in the prevention of influenza compared to influenza vaccination is evaluated. The groups include healthy individuals and those receiving vaccination and colostrum.
After 3 months of monitoring, the number of sick days was 3 times higher in patients who have not taken colostrum. The colostrum group had 13 episodes versus 14 in the colostrum + vaccination group, 41 in the non-prophylaxis group, and 57 in patients who did not take anything.
Part 2 of the study has a similar protocol with 65 high-risk cardiovascular patients, all of whom have underwent prophylactic examinations.
The incidence of complications and hospitalization was higher in the vaccine-only group than in the colostrum-treated group.
Conclusion: Colostrum, both in healthy individuals and in patients at high risk of cardiovascular disease, is at least 3 times more effective than influenza vaccination and is also very cost effective.
