If the choice was AstraZeneca or nothing, AstraZeneca was by far the better choice. While there have been reports of people getting blood clots after receiving that vaccine, there's no evidence that a causal link exists (though it's certainly possible), and the number of cases as a proportion of people vaccinated is miniscule - out of millions of people vaccinated with the AstraZeneca vaccine, the number of blood clot cases reported is only in the dozens.

In other words, as the WHO has already said, the benefits of getting the AstraZeneca vaccine far outweigh any risks.
