General practitioner Julie Sladden was among Jeremy Rockliff's 35-candidate self-proclaimed "team of the decade" announced on Tuesday ahead of the March 23 poll.
Dr Sladden, who is running in the northern electorate of Bass, believes the COVID-19 vaccination mandate had "trodden over" informed consent.
"I was forced to close my practice in the wake of the mandates back in 2021 … because I simply refused to get jabbed," she said in a video posted online in early February.
"That was a personal decision for me, but I also had a very strong ethical opposition to the mandates."
Mr Rockliff said Dr Sladden's views were part of the "broad church" of the party.
When asked how broad was too broad, Mr Rockliff said he welcomed a range of views.
"We have announced candidates from all walks of life," he told reporters on Wednesday.
"That's what Tasmanians want, they want real Tasmanians prepared to step up and stand up for their communities.
"I'm very proud of our team, every single one of them."
The Liberals, who had been in minority for nine months, are chasing a fourth term in government after calling an early election more than a year ahead of schedule.
In the 2021 state election campaign, Liberal candidate Dean Ewington withdrew from the race after his comments describing coronavirus restrictions as silly received media coverage.
"I'm focused on our team. I'm not focused on the past," Mr Rockliff said.
He said Dr Sladden, who has also raised concern about vaccination side effects, would be a passionate advocate for rural health .
Labor MP Dean Winter said his party had serious concerns about Dr Sladden's candidacy.
"Whilst Jeremy Rockliff was health minister … she was calling out Jeremy Rockliff's own policies," he told reporters.
"We're still encouraging people to get boosters for COVID. We're (soon) going to be encouraging people to start getting a flu jab.
"We've got a candidate who is … against the public health advice."
Tasmania's lower house is being restored from 25 to 35 members at the election, with seven MPs to be elected in each of the five electorates.
Opinion polls have indicated it will prove difficult for either major party to form majority government.
The Liberals on Wednesday pledged to halve bus fares for a year from June if re-elected at a cost of $14 million.
Dr Sladden has been contacted for comment.
