The Centers for Disease Control and Prevention (CDC) on December 13, 2021, in a written statement said that booster vaccination or the third dose of COVID-19 vaccination is a powerful way to protect against infection with the variant Omicron .

The latest facts about a booster vaccine that is more effective at protecting against Omicron has been proven in a study conducted in Denmark, launched by Reuters , on Saturday (1/1/2022). This study was conducted on 12,000 households with COVID-19 infection, including 2,225 households with Omicron variant infection.
On another occasion, a study was also conducted in England on 528,176 cases of Omicron and 573,012 cases of Delta. The results, published by the UK's Health Safety Board in collaboration with the unit University of Cambridge's MRC Biostatistics , show the number of hospitalizations for Omicron is lower than for Delta, to be precise one-third of the Delta variant.
Booster Vaccine is More Effective in Protecting from Omicron
1. Contagion Is Still 3.7 Times Higher Than Delta
The results of the study showed that infections still occur rapidly in homes with family members who have received booster vaccine injections. In the Omicron variant, transmission was almost 3.7 times higher than in the Delta variant. This research still needs further action.
2. Low Chances of Infecting
The researchers said the new object of research was limited to transmission that occurred in the household. However, the results of the study also showed that people who had received the booster vaccine were 56 percent less likely to be infected than those who had not received the booster vaccine.
3. Low Chance of Contagion
The results of further studies showed that if Omicron infection occurred in people who had received the booster vaccine, they were less likely to transmit the Omicron variant back to other family members than those who had not received the booster vaccine.
4. Reducing the Risk of Hospitalization
The COVID-19 vaccine plays an important role in this risk of hospitalization. The results of a study conducted in England showed that the risk of hospitalization for the Omicron variant was lower in patients who had received the full dose of vaccination (2 doses) and the booster vaccine (3 doses).
The reduction in the risk of hospitalization was reduced by 81 percent in patients who had received the booster vaccine, when compared to patients who had not received any COVID-19 vaccination. The percentage may be different when compared to patients who have just received 2 doses of vaccination.
However, the Chief Medical Advisor at The UK Health Security Agency (UKHSA) Susan Hopkins, said the results of the research that had been carried out were not sufficient because the object had not been maximized. Similarly, it is too early to draw “definite” conclusions about the risk of hospitalization and increased transmission of Omicron.
CDC Recommendation Booster Vaccination
Then at least six months after the initial vaccine with the Pfizer-BioNTech or Moderna series of vaccine types. While ages 5 years and over, the CDC recommends getting a full dose of COVID-19 vaccination (two doses).
The latest released by research Oxford University researchers on December 13, 2021, launched CNBC , on Saturday (1/1/2022) revealed that two doses of AstraZeneca and Pfizer-BionTech were less effective.
The research was conducted by testing the subjects' blood samples for 28 days, after the second dose was injected. However, the researchers are optimistic that a third injection or booster vaccine could increase immunity to the highly transmissible Omicron variant.
How to Prevent Omicron Variant Infections Apart from Booster Vaccinations
1. Obedient to Use Mask
The way to prevent infection with Omicron variants other than booster vaccinations is to always use masks in public places and indoors with substantial height. The CDC recommends how to prevent this COVID-19 infection by adjusting to the needs.
The World Health Organization (WHO) says a good three-ply medical mask consists of a waterproof outer layer (front), a high-density filtering layer (middle), and a large liquid-absorbing layer to absorb fluids when coughing or sneezing. (the inside part).
The CDC recommendation, the way to prevent COVID-19 infection is to try to use a double mask. Surgical or medical masks inside and cloth masks outside. Experts believe this technique of using masks will increase the effectiveness of mask filtration and block nearly 80 percent of particles.
2. Routinely do a COVID-19 test
How to prevent infection with Omicron variants other than the next booster vaccination, it is recommended by the CDC to routinely carry out COVID-19 tests. The same thing was revealed by the Epidemiologist of the Center for Environmental and Population Health at Griffith University Australia , Dicky said that the test to detect Omicron variants still uses PCR.
"This is also according to the WHO recommendation, PCR is enough. If indeed PCR does not detect Gen S or the Gen S drops out, yes, it is Omicron. It's as simple as that,".
The CDC stresses the importance of understanding and implementing the three ways to prevent infection with the previously mentioned Omicron variants, until researchers know more about the risks of Omicron variants.
