Could Australia Follow Singapore Into Another COVID-19 Wave? November 15, 2021 Despite a high vaccination rate (94%), Singapore is facing a new spike in COVID-19 cases since restrictions lifted in August. Australian infectious disease expert and advisor to the WHO, Dale Fisher, has warned that Australia could see a similar wave next year after a ‘summer honeymoon’. Experts have explained that the recent surge in Singapore is largely due to the waning efficacy of the COVID-19 vaccines which were rolled out earlier than Australia. Many Singaporeans are now lining up for booster shots. One of Australia’s key advantages is our high vaccination rate amongst the elderly, with 94% of over-80s fully vaxxed.
