In response to the very any claims over the pat few weeks about the AstraZeneca Covid vaccine, the World Health Organization – WHO’s experts in vaccine safety gave renewed backing to AstraZeneca’s Covid-19 jab on Friday after they reviewed reports of blood clotting after immunisation with the vaccine.
The World Health Organisation Global Advisory Committee on Vaccine Safety said that the AstraZeneca jab has shown to continue having a positive benefit-risk profile along with spectacular potential to prevent infections and reduce deaths across the world form this COVID-19 pandemic.
The data made available to the public do not suggest any overall increase in clotting conditions, the committee said in a statement. This statement was just after the European Medicines Agency – EM’s approval to the vaccine on Thursday.
The WHO further said rates of so-called thromboembolic events after Covid-19 vaccines were matching with the expected number of diagnoses of these conditions. Deep venous thrombosis and pulmonary embolisms occur naturally and are not very uncommon but may as also occur as a result of Covid-19.
“The observed rates have been fewer than expected for such events”they concluded
“its been observed that very cases of unique thromboembolic events in combination with thrombocytopenia, such as cerebral venous sinus thrombosis (CVST), have also been reported to be very rare over the course of vaccination with the AstraZeneca Covid-19 vaccine in Europe and even at that, it is not certain that they were caused by the AstraZeneca Covid vaccine in the first place. The European vaccine regulators reviewed 18 of thus cases in more than 20 million AstraZeneca Covid-19 vaccinations in Europe, yet there has not yet been a correlation between the vaccine and the conditions. Several European countries have resumed the use of the AstraZeneca Covid vaccine from Friday after the apparent positive go aheads from several authoritative bodies.
However in Indonesia and Venezuela, there has been general worries AstraZeneca’s Covid-19 vaccine causes blood clots and have recently completely stopped the administration of such the vaccines while other countries as Italy, Germany and most other European countries such as Spain, Portugal and Netherland have said they would resume the vaccine after the EMA said it was “safe and effective”.
The WHO committee concluded saying regardless of anything, health care professionals and people being vaccinated should still be given instruction on recognising the signs and symptoms of all serious events after immunisation with the Covid-19 jabs and procedures what to do afterwards.
