Fewer people with a booster report symptoms after COVID-19 contact
Over half of those notified (56%) reported taking a PCR test since being contacted, and 37% said they took a lateral flow test.
Of those who received two doses of the vaccine, 19% developed symptoms, compared with 8% of those who had received two doses and the booster dose.
The proportion of respondents that reported they were currently self-isolating was significantly lower in late November 2021 (6%) than in late October 2021 (15%).
Four in five plan to stay home if unwell over Christmas period
The proportion of adults that reported wearing a face covering when outside their home increased from 84% (between 18 and 28 November) to 94%, following the announcement making face coverings mandatory in certain settings in England from 30 November 2021.
The latest data from the Opinions and Lifestyle Survey also suggest that around half of adults (46%) have had two coronavirus (COVID-19) vaccines and a booster. While 89% of those who have not received a booster said they would be very or fairly likely to if offered.
Prior to the recent approval of the mandatory use of COVID passes in some venues, fewer than 1 in 10 (8%) adults had been asked to show proof of vaccination or a recent negative COVID-19 test in the past seven days (excluding for travel abroad).
Third jab reduces risk of positive coronavirus (COVID-19) test
16 December 2021
People who had received a third vaccine dose were less likely to test positive for coronavirus (COVID-19) than those who had a second dose in the fortnight to 28 November 2021.
Those who reported having had a third dose at least two weeks before had a reduced risk of testing positive compared with those who had had their second dose of AstraZeneca or a second Pfizer dose more than 90 days ago.
Third doses include booster vaccinations.
In the fortnight to 28 November 2021, those who had received at least one vaccine dose remained less likely to test positive for COVID-19 than those who were unvaccinated.
