Therefore, this latest analysis is not suggesting that protection stops after six months, as more time passes and more data is gathered ZOE will continue to monitor and analyse vaccine effectiveness and immunity.
Professor Tim Spector, lead scientist on the ZOE COVID Study app, comments on the latest data: “Regardless of which vaccine is administered, this latest research shows that having a natural COVID-19 infection before double vaccination does mean greater protection.
“This is really positive news for overall immunity levels in the UK and means that large numbers of people will have effective and long lasting protection from COVID-19. This is also strong evidence to support the need for vaccination, even for those who have already had COVID-19.
“When it comes to a booster jab, it’s my opinion that if you’re not in one of the eligible groups for a booster yet, but have a previous infection and two vaccines, you shouldn’t be too worried as your protection will be very high.”
