Booster dose of CoronaVac vaccine protects against Omicron

(ORDO NEWS) — Scientists conducted a study and found that a booster dose of the CoronaVac vaccine, which is produced by the Chinese company Sinovac Life Sciences, is able to protect against Omicron. With its help, it is possible to get a really excellent immune response.

The company said that all participants in the trial were given a booster dose of the Sinovac vaccine six months after the first vaccination.

The results of the study demonstrated that such a schedule for obtaining vaccines can significantly increase the amount of IgG antibodies, as well as increase the level of antiviral cellular immune response. If the third vaccination is given six months after the first, then in this case it is possible to achieve the highest possible result – 88-90%.

Also, the company’s specialists said that literally a month after the third vaccine, an increase in the number of neutralizing antibodies and T-lymphocytes was recorded. Booster vaccination leads to the fact that antibodies begin to be actively produced, which are in the same state for a year from the moment the person was vaccinated.

Additionally, Sinovac Life Sciences has made a statement that a booster dose produces enough antibodies in 94% of cases to neutralize Omicron. It is worth noting that the CoronaVac vaccine basically contains inactivated SARS-CoV-2. WHO has approved the use of the vaccine by people over 18 years of age. The vaccine is given twice. The break should be 2-4 weeks.

To date, experts urge to continue to be vaccinated, so that as a result it will be possible to gain herd immunity. Even if vaccinations from other manufacturers are not so effective in the fight against Omicron, they will still help reduce the risk of infection or the development of quite serious complications of the disease.
