Unlike the other Covid vaccine, Janssen only requires one shot to gain immunity against coronavirus. Around 20 million doses have been ordered, and it’s set to arrive later this year. This follows approval by the Medicines and Healthcare products Regulatory Agency (MHRA) on Friday, May 28. Dr June Raine, MHRA Chief Executive, said: “We now have four safe and effective vaccines approved to help protect us from COVID-19.”
However, Dr Raine emphasised that their work “does not end here”.
“We are continually monitoring all COVID-19 vaccines in use once they have been approved to ensure that the benefits in protecting people against the disease continue to outweigh any risks,” she explained.
What are the risks of the Janssen Covid jab?
The Centres for Disease Control and Prevention (CDC) pointed out the possible side effects of the jab.
The site of injection (the muscle in the upper arm) may be painful, actos actos evista index php it could swell up, and it may also be red.
Throughout the rest of the body, a person may experience:

- Muscle pain
These side effect usually begin with a day or two of having the Janssen injection.

Other signs of anxiety might include rapid breathing, low blood pressure, numbness, or tingling in the body.
The CDC said that such a reaction is “uncommon”, but “not unexpected”, and such a side effect is “generally not serious”.
In America there have been 653 reports of people either fainting or nearly fainting after having the Janssen Covid jab from March to April 2021.
To paint a clearer picture, there were nearly eight million doses of the Janssen jab given in the same time period.
The CDC clarified: “This translates to a rate of about eight fainting events for every 100,000 doses of the Janssen COVID-19 vaccine given.”
All the fainting events occurred during the recommend 15-minute wait after vaccination.
“It’s not clear at this time whether these events were associated with the vaccine or with anxiety,” the CDC added.
How effective is the Janssen jab?
In clinical trials, the Janssen Covid jab was 66.3 percent effective against the disease.
As with the other vaccines offered in the UK right now, people gained the most protection two weeks after getting vaccinated.
“The vaccine had high efficacy at preventing hospitalisation and death in people who did get sick,” the CDC added.
“No one who got COVID-19 at least four weeks after receiving the Janssen vaccine had to be hospitalised.”
As more “real-world” data is collected, the CDC will continue to update the public about the Covid vaccines.
