UK health officials say that vaccines seem to reduce the risk of long covid. They found that people who developed covid-19 were less likely to experience long-term symptoms than people who weren'tvaccinated. They found that vaccines may show promise in reducing symptoms.

The UK Health Security Agency analyzed 15 studies conducted in the UK and elsewhere that looked at various aspects of the relationship between vaccination and long covid symptoms. The studies tried to measure the impact of the vaccine.

The effectiveness of the covid-19 vaccines has waned over time, though they still provide some protection against the coronaviruses. The review found that people who became sick with a vaccine were less likely to report symptoms.

According to the researchers, people who werevaccinated were half as likely to report symptoms lasting longer than 28 days than people who weren'tvaccinated. The group included people who received two doses of the vaccine, as well as people who got the single dose. For people over 60, the vaccine's protective effect was the largest, while for those between the ages of 19 and 38, it was the smallest. The findings of the review were released earlier this month.

The studies add to the potential benefits of getting a full course of the covid-19 vaccine.
