Vaccines are 30 percent less likely to bypass Covid after their first dose and less than half as likely after two doses, a study has suggested.
A study of 300,000 NHS workers in Scotland found that someone living with a health worker was significantly more likely to be positive if the drug was vaccinated.
Scientists are already convinced that jabs can prevent serious illness and death but are not sure how well they will stop the virus from spreading.
Carried out by Public Health Scotland and the University of Glasgow, the study hopes that end-of-virus vaccines could be rolled out across the country.
The findings applied to both the Pfizer and AstraZeneca vaccines and did not look at whether one offered more protection than the other.
And they come after a study yesterday showed that the Pfizer / BioNTech vaccine is 94 percent effective in preventing asymptomatic cases, meaning it could be even better at reducing transmission.

The Public Health Scotland-led study assessed the records of people living with both vaccinated and non-vaccinated healthcare workers, finding that those with a single dose of -at least 30 percent less likely to transmit the virus.
Around 300,000 NHS staff were assessed on the first day of vaccination in Scotland – 8 December – and again on 3 March.
They reached a conservative estimate that the injection prevented 30 percent of transmission between the health care workers and their homes.
But this seems to be much higher because the people at home may have contracted the virus from elsewhere – from an unvaccinated person to the public, for example – but still included in the group. taken from NHS staff.
People who had both doses were at least 54 percent more likely to transmit the virus, the experts said.
Dr Dianne Stockton, director of Public Health Scotland for the Covid-19 Vaccine Monitoring Program, said the results were ‘encouraging’, but emphasized that this should not be made difficult for the public.
She said: ‘Despite this good news, it is important to remember that infection prevention and control practices in healthcare settings are still very important, as are the discounts to prevent transmission in our daily lives. ‘
The risk of transmission has not been reduced to zero after individual health care workers received the vaccine, but global protectionism is likely to be even higher than in this study.
An Israeli study published yesterday revealed that the country’s health ministry believes the injection prevents 97 percent of Covid-19 cases.
In addition, the vaccine was 94 percent effective in preventing asymptomatic cases, meaning it is likely to prevent people from becoming infected at all, thus enabling them to to give.
Those who were unvaccinated were 44 times more likely to develop symptomatic Covid-19 and 29 times more likely to die from the disease, researchers also found.
The study was conducted using data collected between 17 January and 6 March 2021, when the Pfizer-BioNTech vaccine was the only vaccine available in Israel.
‘This clearly demonstrates the power of the Covid-19 vaccine to fight this virus,’ Yeheskel Levy, director of the health ministry, said in a statement.
We aim for greater acceptance in people of all ages, which gives us hope of regaining normal economic and social activity in the future. ‘
Dr Stockton said: ‘As Scotland delivers its national Covid-19 vaccination program, this study provides one more reason why everyone who has been invited to receive a vaccine should take it, because it will not only help protect them from Covid-19, but it will help protect those close to them. ‘
Dr David McAllister, from the University of Glasgow, said: ‘Our study has an important impact on informing vaccine strategies.
The Joint Committee on Vaccination and Vaccination in the United Kingdom recently commented on the lack of evidence in the world assessing the role of vaccine programs in delivery.
‘We provide the first direct evidence that vaccination of individuals working in high-visibility conditions reduces the risk to close relatives – members of their families.
‘Our work will also be of interest to modelists, as it can be used to inform their predictions about future Covid-19 levels in the community.’
More than 23 million people have now received at least one dose of the coronavirus vaccine in England, with the UK-wide vaccination campaign vital to ensure that locked-in locks are reduced.
It comes after smaller official figures surfaced more than half of care home workers have taken part in their Covid vaccine London – Despite working with former residents who are at risk of dying from the disease.
NHS England statistics showed that 74.3 per cent of care home workers across the country had received the first dose of the vaccine by 7 March.
But the data – which breaks the country into 150 districts – show that uptake of the life – saving vaccine among carers and residents is changing across the country.
Lambeth has the lowest proportion of care home staff in south London, with a take-up rate of just 42.6 per cent. In comparison, seven districts have been vaccinated by more than 85 percent, with the Isles of Scilly absorbing all 30 of their care home staff.
All staff in care homes should now have been offered the first dose of the vaccine, with Covid England ‘s vaccine officially extended to people over 55 a week seo.
