The production of antibodies in the first wave of the pandemic may not be effective against mutant COVID-19.


December 28th – Ancha Baranova, a professor at the School of Systems Biology of George Mason University in the United States, said recently that although people infected with the virus in the first wave of COVID-19 have antibodies, they may not be effective in the face of mutant COVID-19.

According to a report by the Russian satellite news agency on the 28th, Baranova believes that those who have contracted the novel coronavirus in the first wave of the epidemic may be infected again with the mutant novel coronavirus found in the United Kingdom and other places: “They may not be able to fully resist secondary infection, which is entirely by luck, depending on the type of antibodies produced in their blood.”

Earlier, British Prime Minister Boris Johnson and scientists confirmed that a new variant of the novel coronavirus found in the United Kingdom is 70% more contagious than the ordinary coronavirus.

The British government also announced on the 19th that the level of COVID-19 prevention and control in parts of the capital, London and other parts, will be raised to a new level 4 to curb the spread of the virus.
