vaccination This is a fundamental principle of pandemic preparation. World Health Organization (WHO) confirmed the effectiveness of existing H5N1 vaccines in livestock. The European Commission has purchased 700,000 doses of the vaccine from CSL Seqirus, with an option to buy up to 40 million more. Finland has also begun vaccinating poultry and fur farm workers.
IN USAthe Department of Health and Human Services has increased its stockpile by nearly five million additional doses of the CSL Seqirus vaccine. However, vaccine Modern drugs based on inactivated viruses grown in chicken eggs are produced slowly. For this reason scientists are developing vaccines based on mRNA technology that are faster to produce and can be tailored to attack emerging strains.
