JEDDAH: The Saudi Food and Drug Authority (SFDA) on Tuesday confirmed 34 cases of blood clots or thrombosis and low platelet count among people who received the Oxford-AstraZeneca vaccine.
“The authority suggests the existence of seven possible cases of thrombosis that are related to the vaccine, due to the absence of other reasons for the appearance of clots in them,” the SFDA said in a statement.
However, the authority also said that thrombocytopenia and blood-clotting immune response associated with the AstraZeneca vaccine is yet to be confirmed in these cases.
It said based on the local reports received, the rate of occurrence of these symptoms in conjunction with the administration of the Oxford-AstraZeneca vaccine in the Kingdom is “very rare.”
The SFDA said that all approved vaccines for the coronavirus (COVID-19) being used in the Kingdom are safe. It stressed that the desired benefits of the vaccine in question outweigh the potential risks.
The authority reiterated that it was continuously monitoring the safety of the vaccines available in Saudi Arabia by studying cases of side effects along with the local and international scientific evidence and data available.
The SFDA advised recipients of the vaccine to consult a doctor or go to the nearest health center if any of the following symptoms appear or continue for more than three days after receiving a vaccine: Dizziness, severe and persistent headache, nausea or vomiting, issues with vision, shortness of breath, severe pain in the chest or abdomen or coldness in the extremities, swelling of the legs, small blood spots under the skin other than the injection site.
Dr. Abdullah Asiri, an infectious diseases consultant at the Saudi Ministry of Health, allayed public fears following the reports.
“How can a wrong conclusion deduced from a generalization become the most circulated news?” he wrote on Twitter. “In short, not every blood clotting after vaccinations is due to vaccinations. Thanks to vaccines, lives are saved every day. We have not yet had confirmed cases of platelet deficiency and blood clotting immune responses associated ‘hypothetically’ with COVID-19 vaccines.”
Dr. Mohammed Al-Abd Al-Aly, a Ministry of Health spokesman, said: “We are still monitoring an increase in the number of COVID-19 infections, which is the highest since the beginning of this year. There has also been an increase in cases among females by 55 percent.”
The Ministry of Health reported 1,070 new confirmed cases in the Kingdom over the past 24 hours, meaning 407,010 people have now contracted the virus. Of the 9,626 active cases, 1,105 were in critical condition. There were 12 fatalities, which brought the national death toll to 6,846.
The ministry said 940 people recovered from the virus over the past 24 hours, meaning 390,538 people have made full recoveries.
