As Covid-19 vaccines continue to make their way across the globe there is hope that people can soon return to some form of normality once they receive the jab.
Restrictions still remain in place in Ireland with Level Five likely to remain right into the end of April.
However, the public has also been told to alter their behaviour on a daily basis in a bid to stop the continued spread of Covid-19.
Now as over 500,000 vaccine jabs have been administered here, a top immunologist has said that people should be allowed to return to certain behaviours after getting the Covid vaccine.
Professor Luke O'Neill shared advice from the Centre for Disease Control in the United States to people who have already got their Covid-19 vaccine saying the same advice should be issued in Ireland.
The advice over in the US states that fully vaccinate people in the US can visit other fully vaccinated people indoors without the use of masks or physical distancing.
It also states that they can visit unvaccinated people who are low risk of severe Covid-19 indoors without a mask or distancing.
They can also refrain from quarantining after coming into contact with an asymptomatic case of Covid.
As of March 5, 513,322 doses of Covid-19 vaccine have been administered in Ireland.
Some 363,601 people have received their first dose while 149,721 people have received their second dose.
America's vaccine rollout has been notably quicker than Ireland's with 30 million people fully vaccinated.
The Deputy Chief Medical Officer Dr Ronan Glynn this week urged people to "keep their guard up" in order to give NPHET more options ahead of April 5 and a decision on restrictions.
Speaking at the HSE media briefing on Monday at the Department of Health, Dr Glynn said: "We need as much improvement as we can through March.
''We are on a good pathway as it stands, but it is a precarious pathway. There are many countries in Europe who have deteriorated in recent weeks.
''The level of the vaccine we have in people - that's not enough to avoid a deterioration or another wave if we drop our guard at this point."
