The Department of Health has been notified of 1,386 new cases of Covid-19.
There are 106 people in hospital who have tested positive for the disease, a rise of 11 since yesterday, of whom 22 are in ICU, one less than yesterday.
There were 1,337 new infections in Northern Ireland and one further Covid-related death there.
Deputy Chief Medical Officer, Dr Ronan Glynn, said: "This pandemic has provided a prime example of how easily misinformation can spread online, and many people have been exposed to information that is false, inaccurate, or misleading.
"This is known as misinformation and it started to spread about potential Covid-19 vaccines even before any had been developed.
"Unfortunately, it has undermined vaccination efforts in many countries, prolonging the pandemic and putting lives at risk.
"All of us together can help to stop the spread of misinformation. Remember, not every post on social media is reliable or accurate - if you are not sure, then don't share."
Dr Glynn added: "In Ireland, we are fortunate to have very high levels of vaccine confidence with fantastic uptake across all age groups to date.
"Of course, many people will have questions about their vaccine but it is important that they access accurate and reliable information in order to get these questions answered.
"Do not rely on unsubstantiated information shared online. Instead go to trusted sources including hse.ie and gov.ie
"GPs and healthcare professionals will also be able to answer any questions you may have when you go to your vaccine appointment."
Also today, a new online application facility has opened to allow people apply for a Covid Recovery Certificate without contacting the Digital Cert helpline.
The online Recovery Certificate portal - Recovery Certificate Portal - will allow people to fill out a form online to request a certificate of recovery.
Elsewhere, Europe's medicines regulator recommended approving the use of Moderna's Covid vaccine in 12- to 17-year-olds, paving the way for it to become the second shot authorised for adolescent use in the EU.
Vaccinating children has been considered important for reaching herd immunity against Covid-19 and in light of the highly contagious Delta variant.
The Delta variant remains a "significant challenge", according to the chair of the Irish Epidemiological Modelling Advisory Group.
Professor Philip Nolan said the size of the next Covid-19 wave depends on what people do to protect themselves in the coming weeks
He believes people have forgotten how easily the virus spreads, adding "we're simply getting too close".
Speaking on RTÉ's Morning Ireland, he said "we cannot let the disease run riot" and people will need "to be careful around this virus for some time".
There has been a four-fold increase in cases, he said, and "where they go next really depends on what we do over the next few weeks".
Prof Nolan said Ireland needs to reach the highest level of vaccine protection in the adult population possible before all or nearly all of the non-pharmaceutical interventions can be relaxed.
He said vaccination offers very high levels of protection and current vaccination rates mean the risk in the population of acquiring a symptomatic infection is now only 30% of what it was, while the risk of severe disease is around 10-15% of what it was.
He said, however, that if the levels of infection are allowed to build up to very high levels, "we're going to be in real trouble", and warned against "the vaccinated feeling inappropriately bulletproof".
Prof Nolan added there is every reason to be optimistic with this pandemic and "we can't be always focusing on dangers and the grimmer possibilities".
But, he said, while there is nothing inevitable about what will happen next, the Delta variant "is a very significant challenge".
Prof Nolan also said there are challenges in relation to vaccinating children, as older teenagers aged 16-18 years pick up disease at higher levels than younger teenagers and those aged from 12-15 years contract and transmit the virus differently.
He said the approach must be to vaccinate the adult protection first before moving on to consider the vaccination of teenagers and then beyond that to consider the vaccination of children.
The Health Service Executive's lead on the vaccination programme said vaccine uptake among the 20-29 age group has been "phenomenal", with 67% already registered or vaccinated through other channels.
Speaking on the same programme, Damien McCallion said the HSE anticipates the vast majority of the adult population will be fully vaccinated by early September, four weeks ahead of schedule.
The date of vaccinations for 16 and 17 year-olds is expected to be announced next week, he said.
Speaking to RTÉ's News at One, Dr Clíona Ní Cheallaigh said that there are benefits in extending the vaccine programme to younger children.
She said that 5-10% of children who are infected with Covid-19 will develop long Covid, which can be very disabling and can make them feel unwell for a long period of time.
She said that a smaller proportion of children will get very sick and require hospital care.
Dr Ní Cheallaigh said cancer patients and people with immuno-compromised conditions would also benefit from having their children vaccinated.
