Will Vaccines Protect against Omicron?
Hello, my whole family has been vaccinated. Will vaccines protect against Omicron? Do we need another vaccine for this? Please elaborate on this.
@anushuya As with most questions about Omicron, we don’t yet know for sure—scientists are racing to collect data to see how effective our current vaccines are against this variant. The very preliminary initial data provides some assurances. At least some of the people who have been infected with Omicron in South Africa have been vaccinated, though we don’t yet know which vaccines they received or when they were vaccinated. But the initial data indicates that those vaccinated people have not become severely ill, meaning that current vaccines may still provide strong protection against serious illness. Pfizer and BioNTech announced that preliminary lab studies showed that three vaccine doses—which people who have received a booster have gotten—appeared to provide robust protection against Omicron. The companies said that antibodies found in blood from people who had received just two doses of vaccine appeared to be less protective against Omicron overall but that there were indications that people who had not yet been boosted may still be protected against severe disease.
