Johnson & Johnson’s one-shot coronavirus vaccine is safe and effective, the US Food and Drug Administration said on Wednesday.
The assessment paves the way for the drug’s emergency use in the US, and experts will meet on Friday to decide whether to approve it.
While it is not bound to follow the advice of its experts, the FDA usually does, and authorised vaccines from Pfizer-BioNTech and Moderna.
J&J said in documents submitted to the FDA that its data suggested its vaccine was effective at preventing asymptomatic infections.
It said that in preliminary analysis of its trial, it found 16 cases of asymptomatic cases in the placebo group compared with two in the vaccine group, or 88 per cent efficacy.
While measuring asymptomatic infection was not the primary goal of the trial, which studied the vaccine’s ability to stop moderate to severe Covid-19, the reduction of asymptomatic cases implied the shot could also cut transmission of the disease.
J&J’s vaccine was, on average, 66 per cent effective in preventing Covid-19 against variants in a global trial involving about 44,000 people, the company said last month.
Its effectiveness varied from 72 per cent in the US to 66 per cent in South America to 57 per cent in South Africa, where a new, highly contagious variant was first identified.
The vaccine was effective in reducing the risk of Covid-19 and preventing PCR test-confirmed Covid-19 at least 14 days after vaccination, the FDA said in its briefing documents.
A fortnight after injection, only two vaccine recipients developed Covid-19 severe enough to need medical intervention, compared with 14 in the placebo group.
After 28 days, no vaccine recipients developed Covid severe enough to require medical intervention, whereas seven in the placebo group did.
Three vaccine recipients had severe side effects in the trial that were probably related to the vaccine.
But the FDA said its analysis did not raise any specific safety concern that would prevent authorisation for emergency use.
The most common adverse reactions were injection site pain at 48.6 per cent, headache at 39 per cent, fatigue at 38.2 per cent and myalgia, or muscle pain, at 33.2 per cent.
Other side effects included a fever in 9 per cent of participants and a high fever in 0.2 per cent of those who received the vaccine.
The regulator said one case of pericarditis, a heart condition, might have been caused by the vaccine.
It said cases of a rare disorder in which the immune system attacks the nerves, Guillain-Barre syndrome, were unlikely to be related to the shot, although data was insufficient to determine whether or not the vaccine had caused it.
J&J had not previously released details of its clinical trial data beyond efficacy rates.

10 tips for entry-level job seekers
- Have an up-to-date, professional LinkedIn profile. If you don’t have a LinkedIn account, set one up today. Avoid poor-quality profile pictures with distracting backgrounds. Include a professional summary and begin to grow your network.
- Keep track of the job trends in your sector through the news. Apply for job alerts at your dream organisations and the types of jobs you want – LinkedIn uses AI to share similar relevant jobs based on your selections.
- Double check that you’ve highlighted relevant skills on your resume and LinkedIn profile.
- For most entry-level jobs, your resume will first be filtered by an applicant tracking system for keywords. Look closely at the description of the job you are applying for and mirror the language as much as possible (while being honest and accurate about your skills and experience).
- Keep your CV professional and in a simple format – make sure you tailor your cover letter and application to the company and role.
- Go online and look for details on job specifications for your target position. Make a list of skills required and set yourself some learning goals to tick off all the necessary skills one by one.
- Don’t be afraid to reach outside your immediate friends and family to other acquaintances and let them know you are looking for new opportunities.
- Make sure you’ve set your LinkedIn profile to signal that you are “open to opportunities”. Also be sure to use LinkedIn to search for people who are still actively hiring by searching for those that have the headline “I’m hiring” or “We’re hiring” in their profile.
- Prepare for online interviews using mock interview tools. Even before landing interviews, it can be useful to start practising.
- Be professional and patient. Always be professional with whoever you are interacting with throughout your search process, this will be remembered. You need to be patient, dedicated and not give up on your search. Candidates need to make sure they are following up appropriately for roles they have applied.
