COVID-19 pandemic gave rise to an increase in demand for pneumococcal and influenza vaccines. Several approaches to improve vaccination rates among different populations were investigated to address this need. Social media may be used as a platform to promote and improve vaccination rates. The study aimed to determine the effect of social media promotion, on the number of patients requesting vaccination in a government tertiary hospital.

The study was conducted using a quasi-experimental design. A telehealth-based vaccination delivery system was established. The need for vaccination against flu and pneumonia was then promoted on a social media platform during the first month of the study. Posters on the risk of not being vaccinated and safety profile of vaccines were added on the second month. The number of requests for vaccination for each month was compared. Social media metrics of the two months of the study were likewise described.

A total of 23 requests for vaccination were recorded, 11 on the first month and 12 on the second month. When a boost in advertising for the posts was implemented, twice as many requests were made during the third week of the second month as compared to the previous month (5 vs 10). Social media promotion with poster showed higher average in reach, engagement and comments per week than without poster. The mean differences among the social media metrics, however, were not statistically significant.

Promotion with posters resulted in a slight increase in number of vaccination requests. Further increase in requests may require a more refined social media promotional strategy.
