New study suggests being fully vaccinated can reduce your odds of having long-term symptoms

A new study of breakthrough Covid-19 infections finds that vaccines not only reduce the risk of severe disease and hospitalization, but can lower the odds of having long-term Covid-19 symptoms too, according to CNN.

The study, which was recently published in the Lancet Infectious Diseases, includes data for more than a million people in the UK who reported receiving at least one dose of a Covid vaccine, through an app. Of those 1.24 million people on the app who received one dose of the coronavirus vaccine, 0.5 per cent developed a coronavirus infection. Of 971,500 people who reported getting a second dose, just 2,370 people (0.2 per cent) reported having Covid-19 at least seven days after their second shot.

Some groups were more vulnerable to breakthrough infections than others, the researchers found, especially following their first vaccine dose: people 60 and older who were considered frail, and people living in “highly deprived areas,” such as densely populated communities. People who were not obese had lower odds of infection following their first vaccine dose, the data showed.

But overall, the researchers found that being vaccinated was associated with fewer reports of symptoms across all age groups if someone contracted the coronavirus. Vaccination, compared with no vaccination, was associated with reduced odds of Covid-19 hospitalization or having more than five symptoms in the first week of illness following a first or second dose, the researchers found, and there were reduced odds of long-term symptoms lasting 28 days or more following a second vaccine dose.
