“…A similar matched case-control study conducted in Qingdao, China, showed a 44.7% vaccine effectiveness for one-dose and an 81.6% for two-dose vaccinations. It is possible that the low one-dose vaccine effectiveness compared to ours is due to the age group included in this study (6)(7)(8)(9)(10)(11) which is reflective of the fact that one dose of the varicella vaccine does not induce an adequate immune response for lifelong immunity. By the age of 5, immunity wanes and hence a second dose is required to boost the immune system [33].…”

“…In Qatar, varicella infection is the second most common notifiable disease, although the vaccine coverage rate is currently estimated at 95%, one of the highest rates in the world [11,12]. According to Qatar's pediatric vaccination schedule (Supplementary Figure S1), two doses of varicella vaccine are provided for free, the first dose is given at 1 year of age and the second dose is given between 4 and 6 years of age [13].…”

Background: Despite the availability of a highly efficacious vaccine, varicella outbreaks are still being reported globally. In this study, we evaluated the real-world effectiveness of varicella vaccination among children between the ages of 1 and 18 years old during the period 2017 to 2019 in Qatar. Methods: A matched case–control study was conducted that included all reported varicella-infected children who visited the primary healthcare system in Qatar from January 2017 to December 2019. The cases were children under the age of 18 years who were clinically diagnosed with varicella. The controls were of the same age, who visited the Primary Health Care Corporation (PHCC) during 2017–2019 with a skin rash where varicella infection was ruled out. The data on varicella vaccination for each participant were obtained from the electronic database in the PHCC during the study period. Results: We included 862 cases of varicella and 5454 matched controls, with a median age of 8 years (IQR 3–12); 47.4% were female and almost 50% were of Qatari nationality. The year 2019 had the highest varicella infection count with a total of 416 cases. The cases were less likely to be vaccinated against varicella, with approximately a quarter (25.6%) of cases and 36.7% of the controls having either one or two doses of the vaccine (p < 0.001). Compared to not being vaccinated, a single dose vaccination showed a 56% reduction in the odds of varicella infection [OR 0.44, 95% CI: 0.34–0.55; p < 0.000], and a two-dose vaccination showed an 86% reduction in the odds of varicella infection [OR 0.13, 95% CI: 0.06–0.29; p < 0.000]. Conclusion: In this multicultural setting, a two-dose varicella vaccination shows reasonable protection against varicella infection.

“…With relatively high per capita health expenditure among the Gulf Cooperative Council (GCC) states, good quality healthcare is provided to all Qatari nationals and residents at greatly subsidized rates [ 19 ]. An existing national immunization program provides protection against 15 vaccine-preventable diseases in line with locally and globally identified disease trends [ 21 ].…”

Key Lessons from COVID-19: A Narrative Review Describing Qatar’s Multifactorial Approach in Executing a Vaccination Campaign

Widespread vaccination programs have been implemented in many countries to curtail the COVID-19 pandemic, with varying success and challenges. To better understand the successes and challenges of the global COVID-19 response in the face of emerging new variants and epidemiologic data, we discuss how Qatar engaged the healthcare sector, governmental bodies, and the populace to combat COVID-19, with a focus on the country’s vaccination strategy. This narrative provides the history and timeline of the Qatar COVID-19 vaccination campaign; factors that helped the vaccination campaign and the transferable lessons learned are discussed. Details regarding how Qatar responded to challenges, such as vaccine hesitancy and mitigation of misinformation, are highlighted. Qatar was one of the first countries to procure the BNT162b2 (Comirnaty®; Pfizer-BioNTech, Pfizer Inc., New York, NY, USA) and mRNA-1273 (Spikevax®; Moderna, Cambridge, MA, USA) COVID-19 vaccines. A relatively high vaccination rate and low case mortality rate (0.14% as of 4 January 2023) was observed in Qatar compared with other countries (global case mortality rate, 1.02%). Learnings will be carried forward as a basis for addressing this evolving pandemic and any future national emergencies in Qatar.

ObjectiveSeptic arthritis is an orthopedic emergency and if not evaluated and treated appropriately, it can lead to poor clinical outcomes. Previously several studies have been performed to identify the etiology of septic arthritis in the pediatric population in developed countries. The main objective of our study was to identify the etiology of septic arthritis in children in Qatar in previously healthy and fully vaccinated children.MethodsWe performed retrospective chart analysis of children presenting to our emergency department between July 2018 and June 2024, who were diagnosed and treated with septic arthritis. The study was conducted at a level 1 pediatric trauma center and the only children's hospital in the country. We used ICD 9 and ICD 10 codes to identify such cases. After using predefined exclusion criteria, children with positive blood cultures, blood titers for Brucella and/or synovial cultures were included in the analysis. Clinical symptoms and signs, ultrasound findings, and culture results were tabulated using descriptive statistics.ResultsA total of 45 patients were included. The median age of children was 5 years (interquartile range [IQR] 2–10 years). Majority (60%) were male. The most common clinical findings were limping/limitation of joint movement (100%), fever (80%), and swelling of joints (58%). The median C‐reactive protein and erythrocyte sedimentation rate were 94 mg/L and 47 mm/h. The knee and hip were the most common joints affected. The most common causative organisms were Staphylococcus aureus (56%), Streptococcus pyogenes (13%), and Brucella (11%). Pre‐intervention imaging, such as ultrasound and/or magnetic resonance imaging, was performed in 95% of patients. All patients recovered without any complications. One of the limitations of our study is that cases of Kingella kingae septic arthritis may be underreported as polymerase chain reaction (PCR) analysis of synovial fluid was not performed on all patients.ConclusionGram‐positive cocci, especially S. aureus, remains the most common cause of septic arthritis in vaccinated children. We also identified Gram‐negative bacilli as causative organisms in our study. We suggest including empiric coverage for both Gram‐ and Gram‐negative bacilli when treating children with suspected septic arthritis till culture results are available.
