J&J’s vaccines combines genetic material from the new virus with the genes of the adenovirus – which causes the common cold – to induce an immune response.
It is the same technology the company used to make an experimental Ebola vaccine for people in the Democratic Republic of Congo in late 2019.
The J&J vaccine can be stored in normal refrigerator temperatures, making it easier to store than Pfizer or Moderna’s vaccines, which use newer mRNA technology.
Unlike the AstraZeneca jab, which requires two doses 12 weeks apart, the Johnson and Johnson jab is a single dose. Picture: File image
Additionally, the fact that J&J’s inoculation is a single shot means it is easier to distribute, especially among people that have difficulty returning for a second appointment.
The Johnson & Johnson single-dose coronavirus vaccine has noticeably milder side effects than either of the vaccines from Pfizer or Moderna.
‘Almost across the board fewer people are reporting side effects,’ Kennedy Dr Richard Kennedy, a professor of medicine at the Mayo Clinic in Rochester, Minnesota, and co-director of the Mayo Clinic Vaccine Research Group, told DailyMail.com.
‘They are more mild. The most common ones are pain at the injection site, which is not surprising since it’s a needle entering your arm, which about 50 percent will experience.’
He said about one-third of recipients report fatigue and muscle pain, 10 to 15 percent report nausea, and about 10 percent report swelling and redness at the injection site.

Comparatively, Pfizer’s and Moderna’s vaccines use a newer platform, part of the pathogen’s genetic code called messenger RNA, or mRNA, to get the body to recognise the coronavirus and attack it if a person becomes infected.
