New findings from the COV-BOOST trial has found that a fourth dose of COVID-19 vaccine can further improve a person’s immune response, beyond that achieved by a third dose.
Research undertaken by a group of researchers from Imperial College London has shown that 19% of people with kidney transplants still have no antibodies to fight COVID-19 after four doses of vaccine.
New findings from a team of researchers at the University of Birmingham show that COVID-19 vaccines provide good levels of protection to people with chronic lymphocytic leukaemia although 20% still produce no antibodies to fight the virus after four vaccine doses.
A group of researchers from the Universities of Kent, Greenwich and Cambridge have shown that serum from the blood of people previously infected with COVID-19, or from vaccinated individuals, can effectively neutralise a bat virus that is a relative of the virus that causes COVID-19.
New research from the team behind the COV-AD study has uncovered ‘strong data’ to support the policy of giving a third primary dose of vaccine to people with weakened immune systems.
The research team behind the PROSECO study has found that treatments for blood cancer often hinder a person’s antibody response to COVID-19 vaccination, but that they are still often able to mount a T cell response.
Researchers working on a range of COVID-19 studies have heard the perspective of people whose immune systems are weakened by an illness or treatment, as part of an initiative to involve patients and the public more extensively in COVID-19 research that affects them.
A study undertaken by UCL and the University of Birmingham has found that the immunity to COVID-19 provided by vaccines declines more sharply in care home residents than in the general population.
