Transition to endemic : acceptance of additional COVID-19 vaccine doses among Canadian adults in a national cross-sectional survey
Background
Additional doses of COVID-19 vaccine have been proposed as solutions to waning immunity and decreased effectiveness of primary doses against infection with new SARS-CoV-2 variants. However, the effectiveness of additional vaccine doses relies on widespread population acceptance. We aimed to assess the acceptance of additional COVID-19 vaccine doses (third and annual doses) among Canadian adults and determine associated factors.
Methods
We conducted a national, cross-sectional online survey among Canadian adults from October 14 to November 12, 2021. Weighted multinomial logistic regression analyses were used to identify sociodemographic and health-related factors associated with third and annual dose acceptance and indecision, compared to refusal. We also assessed influences on vaccine decision-making, and preferences for future vaccine delivery.
Results
Of 6010 respondents, 70% reported they would accept a third dose, while 15.2% were undecided. For annual doses, 64% reported acceptance, while 17.5% were undecided. Factors associated with third dose acceptance and indecision were similar to those associated with annual dose acceptance and indecision. Previous COVID-19 vaccine receipt, no history of COVID-19 disease, intention to receive an influenza vaccine, and increasing age were strongly associated with both acceptance and indecision. Chronic illness was associated with higher odds of acceptance, while self-reported disability was associated with higher odds of being undecided. Higher education attainment and higher income were associated with higher odds of accepting additional doses. Minority first language was associated with being undecided about additional doses, while visible minority identity was associated with being undecided about a third dose and refusing an annual dose. All respondents reported government recommendations were an important influence on their decision-making and identified pharmacy-based delivery and drop-in appointments as desirable. Co-administration of COVID-19 and influenza vaccines was viewed positively by 75.5% of the dose 3 acceptance group, 12.3% of the undecided group, and 8.4% of the refusal group.
Conclusions
To increase acceptance, targeted interventions among visible minority and minority language populations, and those with a disability, are required. Offering vaccination at pharmacies and through drop-in appointments are important to facilitate uptake, while offering COVID-19/influenza vaccine co-administration may have little benefit among those undecided about additional doses.Medicine, Faculty ofNon UBCPediatrics, Department ofReviewedFacultyResearche

Headache in patients with pituitary adenoma: Clinical and paraclinical findings
Aim: The aim of this article is to generate hypotheses for the mechanism of pituitary adenoma headache. Patients and methods: Fifty-eight patients with pituitary adenoma were prospectively analysed for prevalence and manifestation of tumour headache. Intrapersonal and neoplasm-associated risk factors were assessed. Results: Twenty-four patients (41%) had tumour-attributed headache, seven had migraine-like, 11 tension-type headache-like headache, and three both. Cluster headache-like headache was found once, and two headaches remained unclassified. Tumour-attributed headache was associated with a positive history of headache (p = 0.03; OR 3.4), nicotine abuse (p3% (p = 0.02; OR 11.0). For patients with migraine-like tumour-attributed headache, risk factors were younger age (p = 0.02), nicotine abuse (p3% (p = 0.03; OR 14.1). For tension-type headache-like headache, the main risk factor was a positive history of tension-type headache (p = 0.045; OR 5.6). Conclusion: Headache predisposition and local tumour effects might be important for the pathophysiology of pituitary adenoma headache and tumour headache in general
