Third Dose of Vaccine can Boost Immunity Against Omicron by 88 percent: Study

New Delhi: The latest study done by the UK Health professionals on the new variant of Covid-19 found that the third dose of vaccine can boost immunity against omicron by 88 percent. The third dose builds a significantly stronger protective shield against the mutated strain when compared to the second dose.

Dr. Eric Topol – professor of molecular medicine and director of the Scripps Research Translational Institute, said the vaccine effectiveness drops to 52 percent against omicron around six months after the second dose.

That is a big boost of protection for third dose vaccine vs hospitalization from Omicron infection. Vaccine effectiveness increased from 52 percent (due to 2-dose waning after six months) to 88 percent after the 3rd dose,” Dr. Eric Topol said in a tweet.

The UK Health Security Agency (UKHSA) report said that Combined with the protection against becoming the asymptomatic case, this gives vaccine effectiveness against hospitalization of 88 percent (78 to 93 percent) for Omicron after three doses of vaccine.

However, for those receiving two doses of Pfizer or Moderna, the vaccine effectiveness dropped from around 65 percent to 70 percent down to around 10 percent six months after the second dose.
