The major adverse effects reported by the COVID-19 vaccine recipients were pain at the site of injection, fatigue and drowsiness, and headache followed by joint/muscle pain. Differences in adverse events and the severity were compared between inactivated and mRNA vaccine recipients. The factors potentially associated with the reported side effects like age, gender, ethnicity, comorbidities, and previous COVID-19 infection were analyzed based on the type of vaccine received. A survey was conducted among 1,878 adult (≥18 years) COVID-19 vaccine recipients through online survey platforms and telephonic interviews during March to September 2021. Therefore, we aim to investigate the nature and severity of the adverse effects reported and the differences based on the type of vaccine received. 6College of Medicine and Health Sciences, UAE University, Abu Dhabi, United Arab EmiratesĬOVID-19 vaccines have proven to be very safe in the clinical trials, however, there is less evidence comparing the safety of these vaccines in real-world settings.5Ambulatory Healthcare Services, SEHA, Abu Dhabi, United Arab Emirates.4College of Medicine and Health Sciences, Khalifa University, Abu Dhabi, United Arab Emirates.3Sheikh Khalifa Medical City, SEHA, Abu Dhabi, United Arab Emirates.

This may be because it is also the vaccine that's been used most often in the Netherlands. The Pfizer/BioNTech vaccine was most often mentioned in side effect reports. Lareb again stressed that 'in the Netherlands, this specific picture has not been reported so far'. On Sunday the Dutch government decided to pause the use of the AstraZeneca vaccine after reports of a serious combination of thrombosis and a decreased number of platelets in Denmark and Norway. 'The reports now give no reason to believe that thrombosis is a side effect of the coronavirus vaccine,' Lareb said. Lareb received 'several dozen' reports of coagulation problems such as thrombosis and pulmonary embolism on all coronavirus vaccines. 'At present, Lareb does not see any patterns of complaints in the reports that indicate serious side effects from which vaccinees may have died.' In most of these cases, underlying health problems seem to be the most obvious cause of death. 'Almost all had fragile health because of a wide variety of serious underlying health problems and/or advanced age,' Lareb said. The center also received 138 reports of people who died in the period after being vaccinated.

The most commonly reported side effects were muscle pain, headache, and feeling unwell. By March 14, the Netherlands administered approximately 1.89 million coronavirus vaccines.Īccording to Lareb, most of the reported possible side effects were minor and expected side effects. Up to and including March 14, Dutch side effects center Lareb received nearly 11 thousand reports containing 57,391 possible side effects experienced after a coronavirus vaccine.
