Johnson & Johnson's Covid-19 vaccine is likely to be approved in Britain. Here's what makes it different from the others

The Johnson & Johnson vaccine is the first of its kind. It's the first one-shot Covid-19 vaccine, and it could be approved for use in Britain after proving to be effective and safe in a study of 40,000 people. 

After releasing its coronavirus vaccine priority list last December, the UK government is now intent on rolling out these life-saving jabs as quickly as possible. 

Over 700,000 people have been fully vaccinated since the program began, with another 18 million having been injected with their first dose. The three vaccines available in Britain are Moderna, Pfizer, and Oxford vaccines, and all require two doses to provide maximum protection. With the second dose administered between three and twelve weeks after the first, vaccination can take up to three months. 

It looks like this process could be sped up very soon, though, with promising news breaking today that Johnson and Johnson’s one-shot vaccine has been proven to be safe and effective by the US Food and Administration.

The regulator confirmed that the vaccine, which would be the first single-dose injection for Covid-19 if approved, 'met the prescribed success criteria' needed to be authorized for distribution. The FDA will hold a virtual meeting today to discuss the data and decide on their next move. In the likely case that the vaccine is approved, it will be made available for adults in the US within the next few days. 

The UK has already ordered 30 million doses of the vaccines but cannot administer them to the public until its own health officials approve their use. Once they are greenlighted by Britain’s Medicines and Healthcare Products Regulatory Agency, they are likely to accelerate the vaccination rollout pace. Health secretary Matt Hancock said that they would ‘significantly bolster’ the country’s vaccination program if approved. 

In the meantime, those awaiting their first jab can still take measures to increase its efficiency. There are a number of ways to strengthen your Covid-19 vaccine, all of which involve boosting your immune system.
