Findings Of Multinational Global Vaccine Data Network Study Of 99 Mn Vaccinated

A just released study has highlighted a spectrum of complications linked to Covid vaccines, spanning from neurological to heart issues. Guillain-Barre syndrome, a neurological disorder, showed increased risk with viral-vector jabs. Vaccines safeguarding against severe Covid outcomes were associated with slight upticks in neurological, blood, and heart conditions. Notably, mRNA shots were linked to heart inflammation, while viral-vector vaccines raised concerns about brain blood clots. Despite over 13.5 billion vaccine doses administered globally, a small fraction experienced adverse effects, sparking debates on vaccine benefits versus risks. The study, conducted by the Global Vaccine Data Network, scrutinized 99 million vaccinated individuals across eight nations, aiming to identify rare safety signals, notably myocarditis and pericarditis following mRNA vaccination. Published in Vaccine, the research underscores the importance of continual surveillance to ensure vaccine safety. The study concluded that while it confirmed previously identified rare safety signals following COVID-19 vaccination and contributed evidence on several other important outcomes, further investigation is warranted to confirm associations and assess clinical significance. This could be addressed by conducting association studies specific to individual outcomes by applying methodologies such as the self-controlled case series (SCCS) to validate the associations. The Global COVID Vaccine Safety (GCoVS) Project, established in 2021 under the multinational Global Vaccine Data Network™ (GVDN®), facilitates comprehensive assessment of vaccine safety. This study aimed to evaluate the risk of adverse events of special interest (AESI) following COVID-19 vaccination from 10 sites across eight countries. The study periods spanned from December 2020 until August 2023. The total vaccinated population across all sites comprised 99,068,901 individuals. Most vaccine recipients were in the 20–39 and 40–59-year age groups. The study investigated the association between COVID- 19 vaccination and 13 AESIs comprising neurological, haematological, and cardiovascular conditions across 10 sites in eight countries including Europe, North America, South America, and Oceania. In this study including more than 99 million people vaccinated against SARS- CoV-2, the risk up to 42 days after vaccination was generally similar to the background risk for the majority of outcomes; however, a few potential safety signals were identified.
