Even if they catch the virus, people who are vaccinated are less likely to develop long Covid, according to a brief analysis by the UK Health Security Agency.
It examined the available information from 15 research conducted around the world to date.
While some people who are vaccinated contract Covid, the data imply that immunizations minimize the likelihood of infection and illness, including symptoms like weariness.
Unvaccinated people who catch Covid and have long-term symptoms do better if they get vaccinated.
Some of the research included in the study looked at the impact of immunizations administered before infection and discovered the following:
People with Covid who received two doses of the Pfizer, AstraZeneca, or Moderna vaccinations, or one dose of the Janssen vaccine, were nearly half as likely to develop long-term Covid symptoms lasting more than 28 days as those who had one dose or were unvaccinated.
The effectiveness of the vaccine against major long-Covid symptoms was strongest in persons aged 60 and up.
Others who studied the effects of immunizations on patients with long-term Covid symptoms discovered:
Vaccines have the potential to improve rather than aggravate Covid symptoms, either immediately or over time.
Around 2% of the UK population has reported symptoms of lengthy Covid, such as weariness, shortness of breath, and muscular or joint pain, according to the UK Health Security Agency (UKHSA).
These symptoms might linger for up to four weeks following an infection.
People who received two doses of a Covid vaccine are less likely to have symptoms or have symptoms for a shorter period of time.
“These studies add to the potential benefits of receiving a full course of the Covid-19 immunization,” said Dr Mary Ramsay, Head of Immunisation at the UKHSA. Vaccination is the most effective approach to protect yourself from significant symptoms if you become sick, and it may also help to lessen the long-term consequences.
“Symptoms of lengthy Covid are usually short-lived and go away on their own. However, for some people, symptoms might be more severe and cause significant disruption in their everyday life. If you’re having odd symptoms, especially for more than four weeks following an illness, you should see your doctor.”
