AstraZeneca, long regarded as the problem child of the COVID vaccines, is plagued again by negative news. So what\u2019s happened? What does it mean for you? <\/span><\/p>

Short read:<\/strong><\/p>

The overall risk of blood clots is ca. 4 for every 1,000,000 people. The benefits of AstraZeneca vaccine outweighs the risks posed by COVID19 and the vaccine itself for over 40s. Anyone who didn\u2019t suffer from clots should receive their second vaccine when offered.<\/p>

However, as the risks posed by COVID19 to under 30s are lower, alternate vaccines are more prudent for use in this population. This is not out of safety concerns but utmost caution.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What\u2019s happened?
<\/b><\/span><\/p>

In early March 2021, a slew of European countries paused administering the AstraZeneca vaccines after some reports of blood clots began to appear. <\/span><\/p>

As per protocol, all severe adverse effects have to be investigated by the relevant medical authorities. When investigating, authorities look for signs of causation – did A cause B? Or did A and B happen to occur at the same time?<\/p>

Most often, they do this by analysing the rates of occurrence of the event in the general population (or in the specific demographic) and then compare that to the rate of occurrence in the corresponding vaccinated population.<\/p>

Here\u2019s a simplified fictional example of what that means:<\/strong><\/p>

In the general population, say 1% of people over 50 suffer from heart attacks in a one month time period. In the vaccinated population, if this rate is the same or lower, then the event is deemed to not be caused by the vaccine. But if this rate is higher in the vaccinated population, then further investigations or ending of the vaccine trials or drives are required.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What did the investigations show?
<\/b><\/span><\/p>

On March 19th, EU & British regulators stated that the benefits of the AstraZeneca vaccine in preventing COVID19 outweighs any risks posed by it. They investigated ca. 30 cases of clots out of the 20,000,000 people who had received the vaccine in the EU & UK.<\/p>

Following this, Germany, Italy and a number of other countries recommenced their vaccine drives with prudent processes in place.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

So what\u2019s the latest news about?
<\/b><\/span><\/p>

On April 7th, The UK\u2019s major medical body, the MHRA held a press conference in collaboration with the EU’s major medical body, the EMA to discuss their findings.<\/p>

There was confirmation that blood clots have been identified as a \u201cpotential<\/strong> side effect\u201d in \u201can<\/strong> extremely small<\/strong> number of people\u201d (emphasis added).<\/p>

For example, in the 40-49 age group, 0.5 harms can be caused for every 100,000 people. This compares to 51.5 ICU entries with COVID19 in the same age group for every 100,000 people.<\/p>

Most importantly, the benefits of AstraZeneca vaccine was found to far outweigh the risks for the majority of people.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. The vaccine is still safe to administer to the vast majority of people over the age of 30. If you\u2019ve had the first dose and haven\u2019t had the below symptoms, you should take the second dose.<\/span><\/li>\n
