Older people have appealed to Health Minister Stephen Donnelly for clarity on coronavirus vaccines.
The original plan was that everyone aged over-70 would have their vaccine dose by the end of March.
This has now gone to mid-April, with reports it could be pushed as far out as June.
The rollout has also been complicated by the Government's decision to avoid using the AstraZeneca vaccine in older people.
It comes amid concerns over the current limited data around how effective the AstraZeneca vaccine is among that age group.
Richie from Tallaght in Dublin, who is over 70, told Lunchtime Live he just wants to know where he stands.
"We don't know what's going to happen, when we're going to get it.
"We were to get it [in] February, then it was March, now the last I heard on the radio the other day was May."
"So we don't know whether we're coming or going, we can't get anything definite - the HSE says one thing and the [Health] Minister says another thing.
"The leaders are telling other things, so it's totally confusing."
'We're lost, we don't know where we are'
He said they are "living in hope" for a vaccine to get things back "to a bit of reality".
"What we'd love to see as well is a roadmap of how we're going to get out of this - we're locked up now, more or less, for the last year".
"People are confused, and it's playing hell with people's mental health - give us a roadmap".
"We're lost, we don't know where we are, we don't know what we're getting, we don't know what's happening.
"What is the real fact, someone tell us the real fact".
Richie, who is in several WhatsApp groups with friends, said he gave his details to his local medical group - and got a reply the other day.
"I got one the other day that said they hadn't received any vaccines, and they'll keep me up to date.
"I was the only one in our [WhatsApp] group that got a contact from any medical people at all".
He also criticised Minister Donnelly for a lack of answers.
"He's the Minister for Health, he's the boss - he's the one that should come in.
"And then when he does say things - what really annoys me - when he comes out then, he tells us something and then he adds in this word which I hate to hear 'however', and then there's an excuse and it mightn't happen.
"Give it to us definite, tell us what's going to happen, tell us 'A, B, C' what you're going to do".
'Terrified to go out the door'
Rob (71) said the entire vaccine rollout has not taken account of those over-70s with underlying health conditions.
"If you take my own situation for instance, I've got spinal stenosis, asthma, I've got a heart problem, I've had leukemia and I go in once a month to hospital to have my immune system boosted."
He said he called the HSE looking for clarity.
"They told me that they were looking into it and would consider it when the rollout of the vaccine for the over-70s [sic].
"But we haven't heard anything at all, and all the messages coming out of the HSE and the Minister are just totally confusing."
He said other older people in his situation are "terrified to go out the door".
"We can't go anywhere, we're cocooned in our own houses, and it seems to be a category that the HSE, Minister and Paul Reid has forgotten about".
While Paddy Connolly, CEO of Age Action, said there needs to be allowances for the most vulnerable.
"The Government hasn't said that the AstraZeneca vaccine isn't available to people over 70 - what they're saying is that they're prioritising the other two vaccines because they're easier to transport.
"But there is an issue... that for people who have underlying issues who are very vulnerable, who can't reach a GP or a hub, will they be provided with a vaccine - or what vaccine will they receive?"
He said there needs to be an "equality of outcomes" for all people, and that they are fielding calls in relation to the jab.
"Some people want to wait and get the most efficacious vaccine - others will take a vaccine that's available.
"That's an important point to make: if I have the space, the time and the resources to wait, well then it's OK for me to wait.
"But there are other people who don't have the luxury of time in terms of their illness, they may live in crowded conditions.
"So there are people who are very vulnerable who should be vaccinated as a matter of urgency".
