Will the existing vaccines work against Omicron?
Hello, I am 22 years old male. I am double vaccinated. I took a COVISHIELD shot to protect myself from COVID-19. I wanted to know if I am safe or not? Will the existing vaccines work against Omicron?
@luis Hello, there is no evidence to suggest that existing vaccines do not work on Omicron, some of the mutations reported on the Spike gene may decrease the efficacy of existing vaccines. However, vaccine protection is also by antibodies as well as by cellular immunity, which is expected to be relatively better preserved. Hence vaccines are expected to still offer protection against severe disease and, vaccination with the available vaccines is crucial. If eligible, but not vaccinated, one should get vaccinated.
