Yesterday (April 7th) it was confirmed that blood clots should be listed as a “very rare side effect” of the Oxford / AstraZeneca vaccine.
A review by the European Medicines Agency’s Safety Committee carried out a thorough review of blood clot cases in people who received the first burst of the Oxford / AstraZeneca vaccine.
The EMA finding followed an in-depth review of 86 blood clot cases – 18 of which were fatal – on March 22 from around 25 million people who had received the vaccine.
This means the risk of these rare blood clots is around four in a million.
However, women are actually more likely to have a blood clot if they only take one birth control pill each day than if they actually received the vaccine. reports InYourArea.
For example, it is expected that between 10 and four cases of VTE (venous thromboembolism – blood clots in the veins) will occur in every 10,000 women each year when they take the combined pill Yasmin.
Other combined pills can vary between five and 12 people per 10,000; Women who are not taking hormonal birth control have a two in 10,000 chance, while pregnant women who are 6+ weeks after giving birth have a one in two in 10,000 chance.
The UK Government official website Conditions:
- The estimates are not accurate, but women who are not taking birth control pills are expected to have about one case of VTE per 10,000 each year.
- For comparison, it is expected that around six cases of VTE will occur per 10,000 pregnancies. Healthy women taking Yasmin are expected to have between 3 and 4 cases of VTE per 10,000 women per year.
- The previous estimate was between 2 and 4 cases per 10,000 women per year. All of these estimates refer to women who are otherwise in good health.
- The risk of getting a blood clot is very small, but your doctor will check if you have any risk factors before prescribing the pill.
There were many people on social media who were concerned about the vaccine and the confirmation of “very rare side effects”, but there were also women who shared their experiences.
One user replied to InYourArea editor Laura Hartley – one of the women who take Yasmin – saying her own pill (Levest) has a seven in 10,000 risk of blood clots.
Labor MP Jess Phillips tweeted to say she actually suffered a blood clot and we need to take note of how rare this new vaccine information is.
The guidelines on the NHS website state:
Risks of taking the combined pill: There are some risks associated with using the combined pill for birth control. However, these risks are small.
The estrogen in the pill can make your blood clot more easily. If a blood clot develops it can cause:
- deep vein thrombosis (blood clot in the leg)
- Pulmonary embolism (blood clots in your lungs)
- Heart attack
