Johnson and Johnson have announced the preliminary data following a study of 17 people. The results offer new hope for the efficacy of booster shots in fighting the coronavirus pandemic. The vaccine breakthrough follows more and more countries opening up their vaccine hoards for booster shots.
According to Johnson and Johnson, a second dose of the J&J Janssen vaccine offers a ninefold increase in binding antibody levels.
The results were achieved after a second jab was administered six months after the first.
Binding antibodies neutralise the Covid threat by marking the coronavirus as a target for the immune system.
The increase in antibodies was much higher compared to a second shot just 28 days after the first dose.
Johnson and Johnson made the announcement following two, early-stage trials.
Unlike the Pfizer-BioNTech vaccine, the J&J jab is a single-dose vaccine.
However, Johnson and Johnson has not released any data on whether a second dose of its vaccine increased the amount of so-called neutralising antibodies.
Neutralising antibodies protect the system by preventing the coronavirus from entering cells.
According to Dan Barouch, a Harvard vaccine researcher, the data is still being analysed.
Dr Barouch played a role in designing the J&J vaccine but was not involved in the booster study.
The news comes after Israeli researchers found a third shot of the Pfizer vaccine can increase protection against the Delta variant of COVID-19 up to four times.
Israel and the US are among a handful of countries that have begun the rollout of booster shots.
The UK has also announced the imminent start of a booster shot programme.
The need for more protection is all the more pressing as the Delta variant of Covid threatens new spikes of infections.
The Delta variant is more contagious and easier to transmit.
Johnson and Johnson's studies released on Wednesday have shown an increase in binding antibodies in patients aged 18 to 55.
This response was recorded in patients over the age of 65 who were given a lower booster dose.
