People who have been vaccinated against Covid-19 are less likely to suffer from long Covid if they catch the virus than people who haven’t, according to a new review of studies by the U.K. Health Security Agency (UKHSA), underscoring the wide-ranging benefits of vaccination beyond protecting against infection.
People who received one dose of Johnson & Johnson’s single-shot vaccine or two doses of Pfizer-BioNTech, AstraZeneca or Moderna vaccines were around half as likely to develop symptoms of long Covid lasting more than 28 days than those who received one dose or weren’t vaccinated, according to the analysis of 15 studies from around the world by the UKHSA.
The vaccines were most effective at staving off long Covid in people over the age of 60 and lowest for younger study subjects ages 19 to 35, the UKHSA said.
Some of the studies evaluated suggested that getting vaccinated could even help people already suffering from long Covid, with patients reporting either an immediate improvement to symptoms after getting the shot or an improvement over several weeks.
Several studies of unvaccinated people with long Covid suggested that those who went on to receive the vaccine were less likely to report long Covid symptoms after vaccination than those who remained unvaccinated.
