People infected after having vaccine may also be less likely to transmit virus, initial findings show
A government-funded study of care home residents in England has found that their risk of infection with Covid-19 – either symptomatic or asymptomatic – fell by 62% five weeks after they received their first Oxford/AstraZeneca or Pfizer/BioNTech vaccine dose.
Those who were infected after having the vaccine may also be less likely to transmit Covid-19, initial findings showed. The study, funded by the Department of Health and Social Care, is key, given that most clinical trials and observational studies evaluated the impact of the vaccines on symptomatic infections, but whether the vaccines can reduce asymptomatic infections – which play a crucial role in the spread of the virus – is still unclear.
