Dr Amesh Adalja, senior scholar at Johns Hopkins Centre for Health Security in the US, said: Its unclear, at this point, what level of immunity occurs after an Omicron infection. New variants like BA-4 or BA-5, which were unheard of earlier this year, are now circulating in the United States, and they may not be prevented by vaccines, boosters, or the antibodies that you develop when youre infected by another variant.

There have been several variants of concern since the original outbreak of COVID-19. It has been dubbed a stealth variant because it does not show up as clearly as previous sub-variants in laboratories and is harder to identify onPCR tests. This data together shows that a booster jab is the most crucial layer of protection against Omicron. Researchers may be more concerned about reinfection rates when it comes to the rise of another variant that may impact those who have experienced a primary Omicron infection this winter.

Many people are reporting catching the virus for the first timemore than two years into the pandemic, while reinfection is also very common. New variants also tend to be able to reinfect people who have previously caught older strains, due to new mutations in their code. The Gamma variant first appeared in Brazil in November 2020. The answer, he says, lies in spike proteins, the part of a virus that attaches to the receptor on a host cell. The BA.4 and BA.5 lineages have an advanced growth rate due to the relative ineffectiveness of vaccinations.

BA.2, BA.1.1.529 and BA.1.1 arent found in new cases anymore.
