While Covid-19 cases in the United States are set to reach a record high, there is some cause for optimism.  Last week, it was revealed that the Army is developing a vaccine that is resistant against all strains of Covid-19, including future strains.  A study was released that found that you may be immune for life if you catch Covid-19 once, and today, a study was released that indicates that people who catch the Omicron variant of Covid-19 may also be immune to the Delta variant.  The Daily Mail Reports–

“Catching the Omicron variant of Covid may also help people fend off Delta, new research suggests.

Academics took blood samples from people struck down with the ultra-infectious variant and measured their antibody levels. They then looked at how well the virus-fighting proteins reacted to both Omicron and Delta.

Lab tests, conducted two weeks after patients joined the study, showed antibody levels spiked 14-fold in response to Omicron.

But there was also a 4.4-fold increase against Delta, according to the findings which took the researchers by surprise.”

Alex Sigal, a professor at the University of  KwaZulu-Natal in South Africa who led the research, also suggested that the Omicron variant could usher in the endemic phase of the virus.

 ‘The increase in neutralising immunity against Omicron was expected, that is the virus these individuals were infected with.

‘However, we also saw that the same people — especially those who were vaccinated — developed enhanced immunity to the Delta variant.’
