Vaccine: 600,000 Brits receive jab in single day
The Johnson and Johnson coronavirus vaccine has been shown to be 85 percent effective in preventing the most serious Covid symptoms according to the latest data from mass trials anywhere in the world. The vaccine has also been shown to have an overall efficacy of 66 percent against Covid-19. Express.co.uk explores when exactly the Johnson and Johnson Covid vaccine will be available?
The Janssen/Johnson and Johnson Covid vaccine will likely become the fifth vaccine to hit the UK.
The vaccine has shown efficacy against coronavirus, providing complete protection against hospitalisation and death.
Unlike the other vaccines, the Johnson and Johnson vaccine only requires a single dose to be effective.
The vaccine was created by the US giant’s subsidiary Janssen, which is based in Belgium, and was trialled by 44,000 people from the US, South Africa and Brazil.

The UK has ordered a total of 30 million doses of this vaccine.
Further trials involving a second dose of this jab are due to be trialled in the UK.
In the US, the vaccine had 72 percent efficacy in preventing mild to moderate cases of coronavirus, but a lower rate of 66 percent was observed globally in the large trial conducted across three continents and against multiple variants.
The vaccine gave people 85 percent protection against severe illness, even in South Africa which is struggling with a problematic variant of the virus.
The Janssen vaccine also provided 100 percent protection against hospitalisation and death, as do the other vaccines now approved in the US and Europe.
The Johnson and Johnson vaccine can also be kept in a standard fridge, while others require super-cold storage.
Dr Paul Stoffels, the chief scientific officer at Johnson & Johnson, said: “These topline results with a single-shot COVID-19 vaccine candidate represent a promising moment.
“The potential to significantly reduce the burden of severe disease, by providing an effective and well-tolerated vaccine with just one immunisation, is a critical component of the global public health response.
“A one-shot vaccine is considered by the World Health Organisation to be the best option in pandemic settings, enhancing access, distribution and compliance.”
He added the vaccine could “potentially protect hundreds of millions of people from serious and fatal outcomes of Covid-19.”

When will the Johnson and Johnson vaccine be available?
Johnson and Johnson has said it will manufacture one billion doses of the vaccine this year.
The company said a shortage of vaccine factories around the globe has heavily invested in new factories to ensure it meets its targets.
As the vaccine only requires one dose, it could vaccinate up to one billion people.
Unfortunately, the company has refused to outline when the vaccine may be ready for distribution for any country as of yet.
The Johnson and Johnson vaccine uses similar technology to the Oxford University-AstraZeneca vaccine.
This Covid vaccine uses a protein from the spike of the coronavirus, delivered to train the immune system to elicit a response via the common cold virus.
With this coronavirus vaccine, that delivery adenovirus is from humans, rather than chimps which is the case with the Oxford-AstraZeneca vaccine.
By carrying the coronavirus’s genetic code into the body, the body learns to recognise the threat and to then fight it if it ever encounters the virus for real.
When are all Covid vaccines expected to be available in the UK?
There are currently seven major vaccines which are showing promise in the fight to protect people from Covid-19.
The Pfizer-BioNTech vaccine – This jab was approved for use in December and is now being delivered to people.

Valneva vaccine: The vaccine is now being trialled with 150 volunteers at sites across the UK, with a larger trial involving 4,000 individuals planned for April 2021.
Novavax vaccine: The Novavax vaccine will be made in Stockton-on-Tees and is currently being assessed by the medicines regulator. The vaccine is expected to be approved for use in the UK within weeks.
