While antibody levels alone do not predict vaccine effectiveness, the study confirms that two doses of either vaccine are essential to boost antibodies to levels that are likely to maximise the amount of protection against severe disease and hospital admission.
Data from previous studies suggests the higher antibody titres – the greatest dilution level that still blocks 50% of virus infection in the lab – is a good predictor of vaccine efficacy and greater protection against the virus.
