Is it useful for COVID-19 to strengthen the targeting of Omicron? How harmful is Omicron

Recently, the Omicron variant has attracted global attention. As of now, it has appeared in multiple countries and regions such as Austria, Canada, and Australia. Many people are concerned about whether the booster shot is still effective, and whether the vaccine is effective against Omicron? How big is the threat of Omicron? The authoritative answer has arrived! 1、 Is vaccine booster effective against Omicron? The vaccine booster is effective for Omicron. Although the data survey results indicate that the infectivity of Omicron is stronger than that of Delta by 3

7.5%, based on recent cases of Omicron found in South Africa and Europe, many infected individuals have mild symptoms. Currently, everyone is cautious about the strength of the virus, but for now, strengthening the vaccine against Omicron is effective. The specific

reasons are as follows:

Reason 1: Many experts said that the vaccine is more useful for Omikjon. Recently, many experts in China said that the existing COVID-19 vaccine is still effective for Omikjon, and even Academician Zhong Nanshan said that vaccination is also very effective.

Reason 2: There is currently no evidence to suggest that the vaccine has lost its protective effect against Omicron. Based on recent confirmed cases in South Africa and Europe, and after multiple pieces of evidence, the World Health Organization has stated that there is currently no evidence to suggest that the vaccine has lost its protective effect against Omicron. Therefore, strengthening the vaccine against Omicron is effective. Reason 3: Some countries use booster shots to deal with Omicron. When the United States discovered its first confirmed case of Omicron, it mainly used vaccine booster shots to deal with Omicron. Now, with the vaccination of booster shots and effective prevention and control measures in China, booster shots can still protect us from the threat of Omicron. 2、 How big is the threat of Omicron? According to the data survey, the infectivity of the Omikron virus strain is 3

7.5% higher than that of the Deltavirus. Although its infectivity is higher than that of the Deltavirus, they are all COVID-19, and it is impossible to completely break through the immune barrier, because our human body has T cell immunity in addition to antibody immunity. In addition to the current inactivated vaccine, adenovirus vaccine, booster needle vaccine and other vaccines in China, as well as the development of the subsequent second-generation vaccine, they can respond well to the Omikron virus strain. According to the epidemiological report of COVID-19 recently released by WHO, it is pointed out that the most prevalent virus in the world is Delta virus, which accounts for 9.8% of the total, while the proportion of Omikjon virus is less than 0.1%. Therefore, there is no need to panic, do a good job of personal protection, and reduce unnecessary travel. According to statistics, the Omicron virus strain has appeared in Botswana, Canada, the Czech Republic, Australia, Austria, Belgium, Denmark, South Africa, Spain, the United Kingdom, Sweden, Germany, Israel, Italy, the Netherlands, Portugal, Japan, Hong Kong and other countries and regions. Conclusion: Vaccine enhancement is useful for Omikjon. Although the infectivity of Omikjon virus strain is 3

7.5% higher than that of Deltavirus, they are all COVID-19 and cannot completely break through the immune barrier.
