Study | There is a risk of re-infection twice when not vaccinated

(Washington) People who have not been vaccinated are twice as likely to be infected with the Govt-19 virus again than those who have not been fully vaccinated, according to a study released by U.S. health officials on Friday.

According to the Centers for Disease Control and Prevention (CDC), the leading federal public health agency in the United States, the findings of the study confirm that “anyone who is qualified can be vaccinated against COVID-19, regardless of their previous infection status. With SARS-CoV-2,” causing COVID-19 Virus.

Some U.S. politicians, including Republican Senator Rand Paul, have said they do not want to be vaccinated after being infected with the new corona virus because they have natural immunity.

The CDC study was based on 246 adults in Kentucky who were infected with the virus again in May and June this year after being infected for the first time in 2020.

When they tested for gender, age and positivity, they were compared to 492 “case-control” individuals.

According to the study, people who have not been fully vaccinated are 2.34 times more likely to get re-infected than people who have been fully vaccinated against Pfizer, Moderna or Johnson & Johnson.

Researchers are still struggling to understand the exact duration of immunity acquired after infection, and the study suggests that this may be altered by the appearance of new variants.

Laboratory studies show that blood samples taken from people infected with the original strain of the Wuhan virus have a weakened immune system to the beta type, which was first identified in South Africa.

One of the limitations of this study, however, was that it was conducted before the appearance of the delta variant, which is now the dominant strain of the virus in the United States.
