A GP guide to SARS-CoV-2 vaccinations

With multiple vaccines currently or imminently available, we look at their safety, efficacy and recommended use

Need to know:

  • Despite the short time frame since the emergence of COVID-19, a number of safe and effective vaccines are now available.
  • Available vaccines are highly effective at preventing symptomatic disease and very likely effective at reducing severe disease.
  • Vaccine efficacy against asymptomatic disease appears to be lower, making the achievement of herd immunity challenging.
  • Evolving viral adaptations pose additional challenges, with reduced vaccine efficacy against emerging variants of concern.

It has been just over a year since the first case of COVID-19 was reported in Australia on 25 January 2020.

Remarkably, in the 12 months that have followed, multiple safe and effective vaccines have been made available against the causative virus, SARS-CoV-2, with
