Vaccines and their impact
- Vaccines have significantly increased human life expectancy by preventing diseases like smallpox.
- The eradication of smallpox in 1980 stands as a remarkable achievement in human history.
- Brazil's National Immunization Program has played a vital role in protecting the population against preventable diseases.
- Vaccination rates in Brazil were high until 2014-2015 when they started to decline due to factors such as misinformation and waning immunity.
- The decline in vaccination led to the resurgence of diseases like measles.
- The COVID-19 pandemic highlighted the need for vaccines, and Brazil benefited from accumulated knowledge and existing vaccine platforms to develop and distribute vaccines quickly.
- Vaccines have the potential to prevent various diseases, including cancer, autoimmune diseases, and streptococcal infections.
- Vaccination programs have saved an estimated 154 million lives in the past 50 years.
Challenges in vaccination
- Despite the effectiveness of vaccines, convincing people to get vaccinated has been challenging due to the spread of false information and misinformation.
- Political interests often hinder the adoption of knowledge and solutions.
- There is inequitable access to vaccines and resources during pandemics, with wealthy countries having significantly higher vaccination rates compared to poorer nations.
Vaccine development
- Developing a vaccine involves multiple steps, including optimizing the antigen, developing the formulation, conducting preclinical studies in animals, and ensuring industrial-scale production.
- The researcher and his team developed a nasal vaccine called multic covax to induce IgA response in the mucosa, which is crucial in preventing the disease from reaching the lungs.
- The nasal vaccine not only provided systemic protection but also prevented the virus from reaching the lungs, reducing the risk of severe disease and death in animal models.
- Ongoing research and international collaboration are essential to prepare for future pandemics.
Importance of knowledge and passion in global health
- The speaker emphasizes the importance of knowledge and passion in developing solutions to global health challenges.
- They discuss the need to identify the most challenging pathogens, develop effective vaccine platforms, and expedite drug development.
- The speaker stresses the need for inclusive solutions that benefit both developed and developing countries, enabling the prevention of preventable diseases.
