The King’s College London research team behind the ZOE COVID Study app have analysed data from those who have contributed, including logged symptoms, tests and over two million vaccine doses between 8th December 2020 and 4 July 2021.
Their analysis found that for those who contracted COVID-19 after two doses were:
- 73 percent less likely to be hospitalised
- 31 percent less likely to experience acute Covid-19 symptoms.
The research team found that the most common symptoms were similar to unvaccinated adults.
For example, anosmia (loss of smell), cough, fever, headaches, and fatigue. However, all these symptoms were milder and less frequently reported by people who were vaccinated, and they were half as likely to get multiple symptoms in the first week of illness.
Sneezing was the only symptom which was more commonly reported in vaccinated people with COVID-19.
So whilst there is still a risk of contracting COVID-19 after double vaccination, there are clear reductions in the risk of being sent to the hospital, having really bad symptoms or going on to suffer from long duration symptoms,” they wrote.
Health and Social Care Secretary, Sajid Javid had this to say about our research: “COVID-19 vaccines have saved more than 105,000 lives and prevented over 24 million infections in England alone.
“This research is encouraging, suggesting vaccines are not only preventing deaths but could also help prevent some of the longer lasting symptoms.
