Can Thailand achieve COVID-19 herd immunity?

Area of Science:

• Public Health
• Epidemiology
• Health Policy

Background:

• The COVID-19 pandemic significantly impacted Thailand's social, economic, and health systems.
• Initial challenges included vaccine supply shortages and limited options, which have since improved.
• Continuous research monitors population immunity, with a current recommendation for a fourth booster dose for adults.

Purpose of the Study:

• To assess the progress and remaining challenges in achieving herd immunity against COVID-19 in Thailand.
• To identify key barriers hindering vaccination and booster uptake.
• To inform strategies for enhancing vaccine literacy and addressing hesitancy.

Main Methods:

• The study involved continuous monitoring of the COVID-19 situation and population immunity levels.
• Analysis of factors contributing to vaccination program success and challenges.
• Review of public health measures and their effectiveness.

Main Results:

• Despite improvements in vaccine availability, hurdles to herd immunity persist.
• Low vaccine literacy among unvaccinated/inadequately vaccinated individuals is a significant issue.
• Hesitancy towards booster doses presents another major obstacle.

Conclusions:

• Achieving herd immunity in Thailand requires a multi-faceted approach.
• Enhanced health promotion targeting specific groups, like older adults, is crucial.
• Improved distribution systems are needed for equitable access, especially in rural areas.
