Recall that high egg prices are one effect of the bird flu problem. One might suspect its also a factor in rising food prices.
Studies in Europe found two vaccines (for poultry) effective in preventing bird flu and its spread.
“One vaccine was produced by France’s Ceva Animal Health and the other by Germany’s Boehringer Ingelheim”
" The other two vaccines that were tested were produced by Bulgaria’s Huvepharma and Merck Sharp & Dohme (MSD) (MRK.N) respectively." They were apparently less effective.
Field trials are next lasting a year. No details on how soon vaccines could come to market. Progress being made but may still several years away.
