The latest Covid-19 plan from Government represents a very modest easing of restrictions, affecting different people in different times, during April.

Exactly what will happen in May and June and after that is less clear.

So while this is a lifting of some restrictions, given the timescales set out, the horizon may seem further away.

The National Public Health Emergency Team (NPHET) had advised great caution and the announcements reflect much of that.

Nothing new really happens until 12 April and many of the other measures happen closer to the end of the month, such as outdoor training for those under 18.

That's still a long wait for young people, especially with weather improving and longer days of daylight.

Minister for Health Stephen Donnelly said today that the progress so far has to be protected. He also said that today's decisions would open up an opportunity for "a more exciting conversation" about the summer.

Travel within counties will be welcomed with the scrapping of the 5km limit from 12 April. It should also help reduce large gatherings that sometimes resulted from the squeeze of people into 5km.

Some golfers will be frustrated with the delay in reopening that sport to later in April and also the restrictions regarding players.

No inter-county travel until probably July will also cause problems for summer plans.

While hotels and B&Bs may open at the end of June, what about the other areas of hospitality like pubs?

The Tánaiste said that if the reopening of retail, personal services and religious services possibly in May went well, then hospitality can be considered in June.

People who are fully vaccinated will welcome the news that they can meet up indoors with others who are fully vaccinated.

Fully vaccinated means a person has got the second dose of vaccine and 14 days have passed.

This measure to be able to meet up inside is another vaccine dividend, along with the benefit of vaccination itself. And this measure begins now.

In May, the Government will examine a phased reopening of other areas, including additional freedoms for those who are fully vaccinated.

A surprise element in today's package was reform of the National Vaccination Programme to an age-based priority one. That will kick in for people under 64 years of age after Category 8 is done.

Health authorities believe it will be fairer and simpler and also hope it will end lobbying various groups.

The move is also on the back of a review by the National Immunisation Advisory Committee, which found that no occupational group examined is at higher risk of serious disease or death from Covid-19.

But this change has the potential to be controversial and to cause some confusion to people waiting for vaccination.

Already teachers, gardaí, special needs assistants and others are unhappy with what some have labelled a U-turn.

Some groups may feel that the age profile of their profession may push their vaccination dates back.

The Taoiseach said that the change to the system is also due to the fact that the original plan could have delayed the vaccination programme, as it was proving very hard to identify people in the various groups.

The argument is also made that the age-based vaccination system will not distinguish people by their career and older staff who are more vulnerable will be vaccinated faster.

The latest promise is to have six million doses of Covid-19 vaccine administered by the end of July.

Previously, the Government had said that by the end of June, 80% of people will have received a first dose and everyone will have been vaccinated by September.

Opposition parties will be watching closely to see if any of the changes announced will mean that any of the earlier vaccination targets have shifted.

Overall, the new measures are very cautious, conservative, little steps.

The advice from NPHET to Government that Ireland remained susceptible to a fourth wave bore down heavily on the decisions made today.
