Just a fifth of people believe it will be safe to reopen England's schools from June 1, a poll shows today.
Only 21% told a survey it would be safe to partially reopen primary classrooms amid the coronavirus pandemic, while 61% said it will not be safe.
The other 18% didn't know either way, the survey of 1,500 British adults on Friday found.
Meanwhile 64% agreed it would be better to keep schools fully closed until September - even though some children will be "significantly disadvantaged".
And even when it comes to the most disadvantaged children just 34% backed a statement saying they should return in some form this summer.
It comes amid a furious row over Boris Johnson's plans to allow Years R, 1 and 6 to begin returning to England's primary schools in two weeks' time.
Class sizes will be halved to 15 with spaced-out desks, one-way corridors and increased cleaning, while years 2 to 5 return before July.
Ministers are also drawing up plans to help left-behind children over the summer break - which could include opening up for summer schools.
But unions say they cannot support plans to bring back schools in June - not until there is more scientific evidence it will be safe.
Scotland, Wales and Northern Ireland have all refused to back England's plans - while Liverpool and Hartlepool have told schools to stay shut.
Talks on Friday between union reps and government scientific advisers were meant to provide assurance but left more questions than answers.
And today Michael Gove "guaranteed" teachers would be safe - before backtracking and accepting no one could be 100% protected from the virus.
He told Sky News: “The only way in which you can ensure that you don’t get Covid-19 is by remaining at home throughout and having no social contact with anyone.
"We want to proceed in a balanced way in order to ensure children.. have the opportunity to be back in school, benefit from learning and as a result ensure their future can be more secure."
The survey for the Sunday Mirror was carried out by British Polling Council member firm Redfield and Wilton Strategies.
The poll found 86% back a pay rise for NHS doctors, nurses and staff - which the government has stopped short of guaranteeing next year.
In a follow-up question, 73% said this should be a permanent increase in salary that continues after the coronavirus pandemic.
Meanwhile, the poll found 68% believe not enough protective equipment (PPE) was given to care homes.
And 74% said the extent of deaths in the UK from coronavirus could have been avoided.
Asked why they thought that, of those 74%, just over a third (34%) blamed "poor leadership from Prime Minister Boris Johnson."
But despite the damning results, those polled still backed the PM in large numbers.
Asked who the best person to have as Prime Minister was during the pandemic, 49% picked Mr Johnson compared to 27% with Labour's Keir Starmer.
Some 83% backed the government's decision to encourage more people to walk, cycle and drive instead of using public transport.
And only 31% said the PM should resign if the death toll continues to rise substantially - compared to 56% who said he should not.
Meanwhile, the poll found 74% think there should be a legal duty on employers to let staff work from home where possible.
And 76% back carrying on with video or phone GP appointments after the pandemic.
