Being manufactured regionally at Aspen Pharmacare in Gqeberha, Japanese Cape, the second section of the vaccination roll-out is anticipated to get below means by Might.
There are nonetheless many questions on the vaccine itself, so right here’s a short overview of probably the most ceaselessly requested questions.
How does the vaccine work?
The J&J vaccine is a viral vector vaccine which makes use of the shell of a virus – on this case a model of the adenovirus – to hold the gene or DNA for the spike protein on the SARS-CoV-2 virus. Our cells learn the DNA and make copies of the spike protein to set off an immune response. The vaccine itself can not trigger an an infection.
Why is it a single-dose vaccine?
Not like the mRNA vaccines, Pfizer and Moderna, the J&J vaccine is a single dose which makes for a a lot simpler vaccination roll-out. The preliminary knowledge launched by Janssen signifies that the vaccine can adequately train the immune system to recognise and reply to SARS-Cov-2 infections with no need a booster shot.
How efficient is the vaccine?
When safety in opposition to the virus, the J&J vaccine has a 66.3% effectiveness, however it’s essential to notice that it has 85% effectiveness in opposition to extreme illness, and 100% effectiveness in opposition to dying on account of the virus (and this contains the 501Y.V2 variant). That is to say that you just would possibly get the virus, however will probably be a milder model that isn’t life-threatening.
What are the side-effects?
As with most vaccines, you would possibly expertise some side-effects after vaccination, however they are going to be delicate and short-lived. Nobody has developed any extreme allergic reactions, and the J&J vaccine reportedly has milder side-effects than the Pfizer and Moderna vaccines. These embody fatigue, fever, complications, ache on the injection web site or myalgia – ache within the muscular tissues. However these ought to resolve themselves in a day or two.
Can I cease carrying a masks after the vaccine?
We’re nonetheless within the early phases of vaccinations worldwide, which implies practising social distancing, sanitising and mask-wearing will doubtless proceed for a while. Just like the flu shot, the J&J vaccine – in reality all vaccines – shouldn’t be 100% efficient in opposition to SARS-CoV-2, so you would nonetheless contract a milder model of the illness and move this on to an unvaccinated individual. That’s why it’s greatest to maintain practising well being and security even after your vaccination.
