Minors between five and 17 years of age vaccinated against the SARS-CoV-2 coronavirus are less likely than those not vaccinated to develop what has been called long or persistent covid, a report highlights today. journalistic note published in the magazine Nature.
So much Nature and the team that carried out the research consider it important to make known the results of this study, although it has not yet been published in a peer-reviewed scientific journal (at the moment they are only found in the conference proceedings), to encourage vaccination in children over six months.
Jessica Snowden, a pediatric infectious disease specialist at the University of Arkansas for Medical Sciences who was not connected to the study, told Nature that data “is really important. “This will show families how important it is to protect our children, not only from acute Covid, but also from the long-term impacts of Covid.”
For the study, led by Anna Yousaf, from the Centers for Disease Control and Prevention (CDC), 1,600 children were followed weekly for more than a year to detect if they had the presence of SARS-CoV-2; of the 622 participants, ages 5 to 17, who contracted COVID-19; 28 developed long COVID.
The research team calculated that vaccination reduced the probability of developing at least one long Covid symptom by 34%, and of developing two or more symptoms by 48%. But Yousaf says this is likely an underestimate, as the calculation did not consider that the vaccine reduces the chances of developing the infection.
And the girls and boys of Mexico…
Snowden’s comments refer to the fact that in the United States, where the study was carried out, there are families who do not vaccinate their children despite having vaccines available, but also because there are countries where there are no vaccines available for minors.
Mexico is one of those countries, since the reinforcements currently applied by the state, with the Sputnik V and Abdala vaccines, are only for those over 18 years of age, since the vaccines have not been studied in minors. However, the Pfizer covid vaccines that yesterday began to be sold in five pharmaceutical chains with a national presence can be administered to minors with a medical prescription.
According to a meta-analysis published in mid-2022 in Nature (and done by a team led by Mexican Sandra López-León), the most prevalent clinical manifestations of long covid in children and adolescents were mood symptoms (16.50%), fatigue (9.66%) and sleep disorders ( 8.42%). They also had shortness of breath, loss of sense of smell and taste, and fever.
