Jabs offer far higher protection than that needed to prevent hospitalisation and death, Cov-Boost trial lead says
Covid booster shots can dramatically strengthen the body’s immune defences, according to a study that raises hopes of preventing another wave of severe disease driven by the Omicron variant.
In a study published in the Lancet, researchers on the UK-based Cov-Boost trial measured immune responses in nearly 3,000 people who received one of seven Covid-19 boosters or a control jab two to three months after their second dose of either AstraZeneca or Pfizer vaccine.
