接受一劑疫苗後，可以減少許多症狀與危險，

接受二劑疫苗後，可以減少大部分症狀與危險。

(recorded between January 1 and August 31, 2021, i.e. before the emergence of the Omicron variant).

Receiving at least one COVID-19 vaccine dose was associated with a significantly lower risk of respiratory failure, ICU admission, intubation/ventilation, hypoxaemia, oxygen requirement, hypercoagulopathy/venous thromboembolism, seizures, psychotic disorder, and hair loss (each as composite endpoints with death to account for competing risks; HR 0.70-0.83, Bonferroni-corrected p < 0.05)

Receiving 2 vaccine doses was associated with lower risks for most outcomes.
