Should I be worried about COVID-19 vaccines and blood clots?Updated: April 26th, 2021
There have been a few reports of rare blood clots connected to two vaccines, the AstraZeneca and the Johnson & Johnson. The FDA and CDC have called these events “extremely rare” and you can read their full statement here.
On 13th April there had been six reported cases of this clotting condition out of 6.8 million doses of the J&J vaccine given in the US — 0.00009% of cases. Similarly, out of 34 million people who received the AZ vaccine in the UK, EU, and three other countries, 222 experienced blood clots — 0.0007% of cases.
The CDC in the US called a temporary pause on the use of the J&J vaccine to review data and conduct a risk-benefit analysis around the use of this vaccine. As of 23rd April, the use of the vaccine has been recommended to resume,
after a review of all available data at this time shows that the J&J/Janssen COVID-19 Vaccine’s known and potential benefits outweigh its known and potential risks for those recommended to receive it.
The CDC notes that women younger than 50 years old should be aware of the rare but increased risk of blood clots with low platelets after vaccination, and that other COVID-19 vaccines are available. Read the full update here.
We asked Prof. Peter Hotez, an internationally recognized physician-scientist in neglected tropical diseases and vaccine development, whether people should be worried about COVID-19 vaccines and blood clots. Watch the video to hear what he said.
