Unvaccinated frontline NHS staff are said to be looking to move from England to Wales to avoid the mandatory jab rule.
From April 1, all health and social care workers, including nurses in England will be required to have two doses of a Covid-19 vaccine in order to work if their role if it involves “direct contact with patients”.
Frontline staff will not be required to be double-jabbed if they have an exemption.
Staff who refuse to get jabbed or decline to disclose their vaccination status will be offered to switch to a non-patient-facing role.
Those who cannot be redeployed into a new role will face losing their jobs, WalesOnline reports.

The new rule means that for frontline staff to be fully vaccinated by April 1 they will need to have had their first vaccine on February 3.
Wales' First Minister Mark Drakeford said he would "not rule out" recruiting staff who left their jobs because of the mandatory vaccination policy in England.
The rule is not in place in Wales as staff in England are already talking about crossing the border.

In an interview for BBC Radio 4 last week, he was asked if he would take on NHS staff from England.
The First Minister said: "We wouldn't rule it out but it would depend on what anybody said in an interview when they were applying for a job.
"We're not going to make vaccinations mandatory in our NHS.
"We haven't in our social care services because we have succeeded by persuasion by getting the vast majority of people who work in our services to do the right thing and take up the protections that vaccination offers."
He added: "I don't expect us to go looking for people who have not been vaccinated but, if people apply, then they would be interviewed in the normal way.
"We'd look to see what lay behind their decision.
"We wouldn't rule them out but we certainly won't be going out there looking for them."
Chloe, a dental therapist in Plymouth told BBC Newsbeat, says she doesn't want the vaccine and is looking into working in Wales.

The 25-year-old said: "It'll probably be a case of finding a shared house or living with a friend in Cardiff.
"Probably only being able to work two or three days a week then commuting.
"That will obviously put a strain on my relationship [with my partner] because we'll be living separately, and it's just a real hassle."
Chloe doesn't think she should have to choose between her work and the vaccine.
She said: "I think it's disgusting they're doing this. They're taking away our human rights.
"I don't think it's very fair that just across the border in Wales, the laws are going to be completely different."
