CDC: Natural immunity after infection with Delta variant is more effective than vaccines

A study published by the US Centers for Disease Control and Prevention (CDC) on January 19 showed that, for the Delta variant – the predominant SARS-CoV-2 virus strain in the first half of 2021, people Vaccinated people are 6 times less likely to get Covid-19 than those who have not been vaccinated.

However, people who have been infected with this variant before, but have not been vaccinated, will be 15 to 29 times less likely to contract Covid-19.

Similar differences were observed in hospital admission rates, with people who had previously been infected with the Delta variant had better immune systems than those who had been vaccinated. However, the CDC emphasized, vaccination is still the safest way to prevent Covid-19 infection. That’s because “catching Covid-19 for the first time carries significant risks,” study co-author Dr Eli Rosenberg told CNN. In the same opinion, Dr. Erica Pan, an epidemiologist with the California Department of Public Health also recommends that even people who have had Covid-19 still get vaccinated to ensure they have “an extra layer of protection”. “./.
