SARS-COV-2: Reduced risk of developing long COVID after double vaccination.


SARS-COV-2 infection after double vaccination is associated with a reduced risk of developing long COVID symptoms at least 12 weeks later. This highlights the importance of public health initiatives to increase vaccination at the population level. However, scientists warn that studies with longer follow-ups are needed to assess the impact of booster doses and the Omicron variant and to assess symptom trajectories much further than 12 weeks. This is especially important given the relapsing nature of long COVID.
