Hussain emphasized the vital role of vaccines in disease prevention and said, “Health systems in many countries, whether rich or poor, are still based on the medical model of disease treatment and management. This model is fine, but why should people get sick in the first place? This is where the role of the vaccine is highlighted as a key tool for primary prevention.

He also highlighted Iran's rich history in vaccine production, noting the Islamic Republic of Iran, having strong institutes and outstanding scientists, has played an important role in providing public health. An example of these efforts is Razi Institute, which has played a significant role in the production of human and animal vaccines and has significantly contributed in the eradication of diseases such as polio and Covid-19.

He also stressed the need for intersectoral collaboration, citing that public health can no longer be guaranteed by a single ministry, the partnership between the Ministry of Health and the Ministry of Agriculture Jahad as a model for integrated health strategies.

Praising Razi Institute's achievements, he remarked, “This institute is among the few worldwide that has successfully produced recombinant and intranasal vaccines. It has the potential to enhance scientific capabilities in neighboring countries and regional health challenges.” Also, considering common regional challenges, including vaccine production and combating antibiotic resistance, this institute can play a central role in health promotion in low-income and middle-income countries.

In closing, Hussain congratulated Razi Institute's management and staff, reaffirming WHO's commitment to support the institute through technical and scientific collaboration and to pave the way for the production of more advanced vaccines. He concluded, "Vaccine production not only saves lives but is crucial for global health security.”
