Abstract

The present study reviews the impact of vaccination program strategies in preventing infectious diseases spread, focusing mainly on COVID-19. Vaccination is crucial in achieving herd immunity and infectious diseases spread preventing. The COVID-19 vaccine is classified as a primary vaccine, since it is intended primarily for prevention in susceptible populations. So far, over 5.55 billion people have received at least one dose of the COVID-19 vaccine globally, accounting for approximately 72.3% of the world's population. However, vaccine hesitancy and access to vaccines pose significant challenges to achieving global vaccination coverage. To ensure equitable access to vaccines worldwide, efforts to address these challenges, such as increasing vaccine production capacity, improving distribution channels, and implementing effective communication and education campaigns, are crucial. While all the strategies discussed herein can be useful in different contexts, fractional dosing and intradermal vaccination may be more suitable for lower-income countries due to their cost-effectiveness, while heterologous vaccine regimens may be more suited to higher-income countries with greater access to multiple types of vaccines.
