According to a study released today by U.S. health officials, people who are not vaccinated are twice as likely to be infected with the Govit-19 virus than those who are fully vaccinated.
According to the Centers for Disease Control and Prevention (CDC), the country’s leading public health agency, the study supports the recommendation that “everyone who is infected with SARS should be vaccinated. CoV-2”, the virus that causes the disease.
Some U.S. politicians, including Republican Sen. Rand Paul, have announced that they do not want to be vaccinated because they already have natural immunity. Corona virus.
The study was based on a sample of 246 adults from Kentucky.
They were compared to 492 individuals in a “control” group based on gender, age, and date of diagnosis.
According to the study, those who are not vaccinated are 2.34 times more likely to relapse than those who have been fully vaccinated by the vaccines of Pfizer, Moderna or Johnson & Johnson.
The exact duration of immunity acquired after infection is not yet clear, and researchers say it could be altered by the appearance of new variants.
For example, laboratory studies have shown that blood samples taken from people infected with the original strain of the Wuhan virus show a weakened immune system against the beta variant first identified in South Africa.
One of the limitations of this study was that it was carried out long before it appeared Delta variant, Which is the strain that now dominates the United States.
