There is also some suggestion that a vaccine can help reduce long Covid symptoms.
The British Heart Foundation (BHF) says: “In research published in October 2021, the Office for National Statistics used data from the UK Coronavirus Infection Survey to look at the association between COVID-19 vaccination and long Covid in people who already had it before the vaccine.”
The researchers found that the first vaccine was associated with an initial 13 percent decrease in the likelihood of self-reported long Covid.The second dose was associated with a nine percent decrease in the likelihood of self-reported long Covid, relative to having received the first vaccination, and there was statistical evidence of a sustained improvement after this.
The BHF states: “Which vaccine was used (Pfizer, AstraZeneca or Moderna) didn’t appear to make any difference to the results. Nor did the person’s age, ethnic background, gender or other health issues.”
