The UK has ordered 30 million doses of the Janssen vaccine, which uses similar technology to the Oxford jab. It has just been announced that the single dose vaccine has just been approved. What are the side effects to be aware of?
In an ongoing clinical trial, the Janssen COVID‑19 Vaccine has been shown to prevent COVID‑19 following a single dose. The duration of protection against COVID‑19 is currently unknown.
According to the US Food and Drug Administration, the most commonly reported side effects were pain at the injection site, headache, fatigue, muscle aches and nausea.
“Most of these side effects occurred within one to two days following vaccination and were mild to moderate in severity and lasted one to two days.
Janssen listed the symptoms of an allergic reaction to the vaccine which include:
Swelling of your face and throat
A fast heartbeat
A bad rash all over your body
Dizziness and weakness
Janssen said on their site: “Blood clots involving blood vessels in the brain, abdomen, and legs, along with low levels of platelets (blood cells that help your body stop bleeding), have occurred in some people who have received the Janssen COVID-19 Vaccine.
“In people who developed these blood clots and low levels of platelets, symptoms began approximately one to two weeks following vaccination.
“Most people who developed these blood clots and low levels of platelets were females ages 18 through 49 years.”
