Sumary of You’re much less likely to get long COVID if you’ve been vaccinated:
- Increasing COVID-19 vaccination rates as quickly as possible is currently a major focus for Australia.
- Doing so has clear benefits in reducing new infections and preventing severe disease, hospitalisation and death.
- One question which is frequently asked is – does COVID vaccination prevent you from getting long COVID?
- There has been much international debate as to the definition of long COVID, how common it is, and how long it may last.
- Studies examining the frequency of long COVID range from anywhere to over 80% in hospitalised patients with severe initial illness, to as low as 2-3% in one large app-based study of largely young healthy people in the United Kingdom.
- A recent review of 45 studies and almost 10,000 people suggested almost 75% of them reported at least one persistent symptom at 12 or more weeks after COVID infection.
- Many of these studies are highly dependent on the choice of people studied, and whether they required a definite confirmation by positive swab testing.
- The Australian ADAPT study (led by myself and other colleagues from St Vincent’s Hospital, Sydney), enrolled people who’d had confirmed positive PCR tests, as well as a mix of hospitalised people and those who didn’t go to hospital.
