A new Covid-19 vaccine, which requires only one dose as opposed to the usual two, is allowed to be used by the UK medicines regulator.
The Janssen vaccine, which can be stored at a fridge temperature, between two to eight degrees Celsius, is approved by the Medicines and Healthcare Regulatory Agency (MHRA).
“The Janssen vaccine will be a weapon in our arsenal to defeat this pandemic”
A total of 20 million doses have been secured for all four UK countries and the first delivery is expected to arrive later this year.
Studies from earlier this year showed that the single-shot vaccine was 67% effective overall to prevent Covid-19 infection and 85% effective to prevent serious illness or hospitalization.
This is the fourth vaccine approved for use in the UK.
Separately, the Cov-Boost study examined whether janssen jab could be safe and effective as a third-dose vaccine for a potential booster program, which could begin later this year, according to the government.
Health and health secretary Matt Hancock said the news was a “further strengthening of the UK’s immunization program”, which he said had “saved more than 13,000 lives”.
“As Janssen is a dose vaccine, it will play an important role in the coming months as we redouble our efforts to encourage everyone to get their jabs and possibly start a booster program later this year, “he added.
Vaccine delivery minister Nadhim Zahawi said: “The Janssen vaccine will be another weapon in our arsenal to defeat this pandemic.
“We’re doing everything we can to get all the adults vaccinated as soon as possible and I encourage everyone to go ahead for a jab once they qualify.”
The government initially got 30 million doses of Janssen vaccine, but has now decided it only needs 20 million.
The Joint Committee on Vaccination and Immunization (JCVI) will submit updated advice for the Janssen vaccine before the dose is applied.
The single -dose vaccine is also approved by the European Medicines Agency (EMA), Food and Drug Administration (FDA) and the World Health Organization (WHO).
The government claims it remains on track to offer all adults the first Covid-19 jab by the end of July.
