Background: Pneumonia has been associated with high morbidity and mortality rates; it could be prevented or reduced by vaccination. Objectives: To assess the knowledge attitude and practice (KAP) of Saudi adults toward pneumococcal vaccine commitment and benefits. Methods: This was a qualitative cross-sectional study that was conducted electronically from April to August 2021 among the general population in Kingdom of Saudi Arabia to elaborate people\'s awareness about the importance of pneumococcal vaccine. Results: The study included 13,280 participants. The level of knowledge regarding pneumococcal vaccine was poor among 65.7%, moderate among 24.6% and good among 9.7% participants, while the attitude was positive among more than half of the participants, neutral among 32.2%, and negative among 9.1%. The level of practice was wrong among 43.7%, right among 31.1%, and not complete among 25.2%. The good KAP levels were significantly associated with adult males who had high educational degree and work as healthcare professionals. Conclusion: The study showed poor knowledge among most of the participants with positive attitude toward practicing pneumococcal vaccine. The poor knowledge about the essential value of pneumonia vaccine as well as lack of advice by health care providers need to be addressed in the national program for pneumonia vaccine.

Among infectious illnesses, tuberculosis (TB) has the highest fatality rate. The likelihood of infection spreading from patients to healthcare providers is two times higher than in the general population. The primary risk factor for contracting TB is close proximity to an infected individual prior to diagnosis. The research assessed health workers’ knowledge, attitude, and practice of TB infection control in Saudi Arabia. The study used a cross-sectional approach based on an online survey. The research was carried out throughout the months of May to July 2022 in Al Madinah Al-Munawara. The questionnaire included demographic’s and work variables, knowledge regarding pediatric TB etiology, transmission, symptoms, lymph node characteristics, and diagnostic criteria. Also, the participants’ perspectives and practice patterns on contact investigation, TB diagnostic tools, laboratory services, presumptive TB diagnostic referrals, and TB treatment were evaluated. The study included 558 healthcare workers (HCWs) from various specialists. HCWs exhibited sound knowledge, and positive attitudes in comparison to those with minimal experience in diagnosing TB in children TB as 31.2% had excellent knowledge, 22.6% good, 18.5% mediocre, and 27.8% bad. The majority of responders (49.1%) had a positive attitude, while only 33.2% had correct and full practice routines. Immediate action is required to increase HCW awareness, capacity, and skills to ensure an accurate diagnosis. In the identification of TB cases, certain crucial information gaps were discovered. This study also highlights the significance of clinical experience and frequent interactions with tuberculosis patients in clinical practice as a pathway to competency-based learning by practice.
