・have three doses of the corona vaccine

have/get three doses
可以用來表示「三劑接種」。

新冠肺炎疫苗可以稱為the corona vaccine/the shot/the jab因此可以表達為
have/get three doses of the corona vaccine

I have had three doses of the corona vaccine.
『我已經接種了三劑新冠肺炎疫苗。』

順便說一下，副作用是side effect
I had my first dose of the corona vaccine and the side effects were very painful.
『我接種了第一劑新冠肺炎疫苗，副作用非常痛苦。』
