• Viral Vector Vaccines –
– Introduce genetic code for antigen into harmless virus which then
introduced in human body
• Nucleic Acid Vaccines –
– Insert genetic code directly into cells - like mRNA or DNA vaccines

4. EFFICACY VS EFFECTIVENESS
• Efficacy Rate - degree by which infection is reduced in a vaccinated
group compared with an unvaccinated one - it measures disease
prevention by the vaccine among trial participants
• Efficacy of a vaccine indicates its success in a randomised controlled trial
• Effectiveness measures how the vaccine works in a real-world setting
• Real-world effectiveness is usually less than in a controlled setting
• It takes many years for science to determine what an effective vaccine is
