'No evidence' to limit use of AstraZeneca COVID vaccine

The government has cleared the Astra Zeneca vaccine following fears it causes blood clots

In a report out Thursday, the U.K.'s drug safety regulator said it had identified more cases of thrombosisamong recipients of theOxford/AstraZeneca vaccine, bringing the total to 30 - though it said the benefits of the shot still far outweigh the risks.

According to Johns Hopkins, 993,717 COVID cases are registered in Canada with an overall 22,993 COVID-related death cases reported.

On March 18, the United Kingdom medicines regulator said that there had been five cases of a rare brain blood clot among 11 million administered shots.

Earlier Friday, a Dutch organisation that monitors vaccine side effects said it had received five reports of blood clots with low blood plate counts following vaccinations.

Earlier this week, the European Union drugs regulator said a link between the AstraZeneca vaccine and a rare type of blood clot is possible, identifying at least 62 cases of the condition. A number of European countries have suspended the use of the jab following the detection of blood clots in the brains of vaccinated people.

"Based on all of the evidence available internationally to date, Health Canada continues to consider that the benefits of the AstraZeneca and COVISHIELD vaccines to protect against COVID-19 outweigh the potential risks", the statement read.

When the EMA declared the vaccine "safe and effective", they resumed its use while investigations continued.

The EMA, which has assessed data from around the world, estimates there is around a one in 100,000 risk of a CVST in people under the age of 60 who have been given the Oxford-AstraZeneca vaccine.

"If you receive the AstraZeneca vaccine and you experience symptoms of severe, persistent headache or other worrying symptoms, four to 20 days after the vaccine, you should seek medical advice as soon as possible", he said.

People who have tested positive for coronavirus within the past six months will only have to have one dose of vaccine, public health institute RIVM said on Friday.

Estimates vary from around two cases per million people every year to almost 16 in every million in normal times and coronavirus itself may be causing them too.

The recommendation applies to all three vaccines now being used in the Netherlands - AstraZeneca, Pfizer/BioNTech and Moderna.

CVSTs are inherently more common in younger women and taking the pill increases the risk.

Messenger RNA (mRNA) vaccinations include those made by Pfizer-BioNTech and Moderna.

The UK has ordered seven vaccines and expects to receive 407 million doses - more than enough for every adult to receive two.
