Corona virus infection has been reported in many cases around the world, with many being re-infected after recovery. One study found that un-vaccinated people were twice as likely to be re-infected with the corona virus than vaccinated people. The study was conducted by the US Centers for Disease Control and Prevention (CDC).
The company released the research data last Friday.The CDC said that the recommendations of the study support the recommendations they have made on vaccines. Their recommendation is that everyone who is able to get the corona vaccine should be vaccinated. Even if a person has been infected with corona before, he or she must be vaccinated.
The new study looked at 248 people in the southeastern United States. These individuals were re-infected between May and June last year after being infected with corona last year. They were compared with 492 volunteers.Studies have shown that people who are not vaccinated are 2.34 times more likely to be re-infected with corona than those who are fully vaccinated. The study involved volunteers receiving two doses of Pfizer and Modern or one dose of Johnson & Johnson.
The study said it was not yet fully known how long a naturally occurring immune system could survive coronary heart disease. Antibodies to earlier types of corona virus infections may not work the same way on new types.For example, laboratories have found that antibodies found in the blood samples of infected people in the first strain of corona virus spread in Wuhan, China, are less effective against the beta strain in South Africa. The study was carried out before the delta type of corona formed from India spread to the United States.
