Background: The objective of our study was to evaluate vaccine type, COVID-19 infection, and their association with stroke soon after COVID-19 vaccination.

Methods: In a retrospective cohort study, we estimated the 21-day post-vaccination incidence of stroke among the recipients of the first dose of a COVID-19 vaccine. We linked the Georgia Immunization Registry with the Georgia Coverdell Acute Stroke Registry and the Georgia State Electronic Notifiable Disease Surveillance System data to assess the relative risk of stroke by the vaccine type.

Results: Approximately 5 million adult Georgians received at least one COVID-19 vaccine between 1 December 2020 and 28 February 2022: 54% received BNT162b2, 41% received mRNA-1273, and 5% received Ad26.COV2.S. Those with concurrent COVID-19 infection within 21 days post-vaccination had an increased risk of ischemic (OR = 8.00, 95% CI: 4.18, 15.31) and hemorrhagic stroke (OR = 5.23, 95% CI: 1.11, 24.64) with no evidence for interaction between the vaccine type and concurrent COVID-19 infection. The 21-day post-vaccination incidence of ischemic stroke was 8.14, 11.14, and 10.48 per 100,000 for BNT162b2, mRNA-1273, and Ad26.COV2.S recipients, respectively. After adjusting for age, race, gender, and COVID-19 infection status, there was a 57% higher risk (OR = 1.57, 95% CI: 1.02, 2.42) for ischemic stroke within 21 days of vaccination associated with the Ad26.COV2.S vaccine compared to BNT162b2; there was no difference in stroke risk between mRNA-1273 and BNT162b2.

Conclusion: Concurrent COVID-19 infection had the strongest association with early ischemic and hemorrhagic stroke after the first dose of COVID-19 vaccination. Although not all determinants of stroke, particularly comorbidities, were considered in this analysis, the Ad26.COV2.S vaccine was associated with a higher risk of early post-vaccination ischemic stroke than BNT162b2.

Overview Hypertension and Vitamin D  Overview Cardiovascular and vitamin D

Stroke more likely if low Vitamin D

• Stroke 74% less likely if high vitamin D (7,295 women 20-50 years old) – July 2017
• Stroke is 13.5 X more likely if low vitamin D and high blood pressure – March 2015
• Ischemic stroke 17 X more likely if low vitamin D – April 2017
• Stroke is strongly associated with Calcification of cerebral arteries (perhaps low Vitamin D, Vitamin K, Mg…) – March 2018
• Ischemic Stroke 3X more likely if Vitamin D Receptor gene change (Fok 1) – Jan 2014

Post-Stroke worse if low Vitamin D

• Poor Acute Ischemic Stroke 4X more likely if low Vitamin D - Nov 2023
• Stroke risks increased if low Vitamin D: Death 3.6 X, recurrence 5.5 X – Meta-analysis Nov 2019
• Stroke outcome at 3 months was 3X worse if bad stroke and low vitamin D – Jan 2020
• Death after Ischemic Stroke 2.5 X more likely if less than 10 ng of Vitamin D – May 2019
• Vascular dementia (after strokes) 32X more likely in Hypertensives with low vitamin D – Oct 2015
• Depression following a stroke is 2.7 X more likely if low vitamin D – Sept 2018

Post-Stroke better if add Vitamin D

• Post-stroke Vitamin D supplementation helped in 11 ways – May 2023
• Improved recovery from ischemic stroke with Vitamin D (300,000 IU injection) – RCT June 2018
• Better outcome following Ischemic stroke if injected with 600,000 IU of vitamin D – RCT Feb 2017
• Ischaemic stroke – Vitamin D doubled survival (Injection followed by monthly 60,000 IU) – RCT Aug 2016
• Stroke patients need more than 2,000 IU of vitamin D (found this time in Japan) – RCT June 2019
