Vaccine and borders A number of recent letters make an optimistic link between the coming Covid vaccines and possible relaxation of border quarantine restrictions.
The efficacy of the vaccination against symptomatic disease is good but, unfortunately, the available published data from the large efficacy trials show that vaccination does not prevent the acquisition and asymptomatic carriage of this virus.
It may somewhat reduce the chances of asymptomatic infection (this is not yet established) but being vaccinated will not mean that an apparently healthy person can avoid quarantine as they could still be a superspreader.
