The new crown virus mutation to Omikerong has exceeded their own expectations of the mutation of the new crown virus, the mutation strain of Omilon's strong transmission capacity can be hidden so that many countries in the epidemic prevention department can not prevent, now all countries in the world have begun to vaccinate against the new crown vaccine, most countries vaccination coverage has exceeded 80%, but the infection of Omikeron is still there, the vaccine for the prevention and control of the new crown epidemic is not as optimistic as people once imagined.
The advent of Omi kerong weakened the effectiveness of vaccines
The United States has the ability to independently develop a new crown vaccine, the United States Pfizer vaccine is more than 90% effective against the new crown virus, after the second dose of vaccination, the ability to infect the new crown virus has been improved, can be effective substances new crown virus into the human body to cause damage. When the third dose of the new crown vaccine is completed, the level of antibodies to the new crown virus in the human body increases rapidly. But for the current global rage of Omilon, the protection of the new crown vaccine has weakened significantly, and the effectiveness of the vaccine has made people questionable.
Even after receiving the third dose, you will still be infected
The problem of declining vaccine protection is not limited to the United States. Vaccination coverage in the UK is now close to 90%, with 82.6% having completed a second dose and nearly 60% having completed a third. It is such a high vaccination coverage that still has not broken free from the poisonous claws of the British mutant strain Aomi Kerong, and the number of new cases in the United Kingdom in a single day has exceeded 200,000. Experts have been calling for a third dose of the vaccine, saying that the third dose of vaccination can effectively prevent the infection of Ami Kerong, but in the face of such a huge number of new cases, the experts' words are obviously not highly credible.
The fourth injection is not 100% guaranteed not to be infected by the virus
Some people say that since the third shot can not let people avoid the infection of Omicron, then continue to inject the fourth dose of vaccine, in fact, the reason why the new crown virus mutates in the human body is that the new crown virus attacks the human immune system, thereby changing its own mutation point to ensure that it can invade the human body. Recently, Israel has taken the lead in launching the fourth dose of the new crown vaccine. According to studies, people who have already received a fourth injection have a five-fold increase in the number of antibodies produced in their bodies, and then whether a fourth injection, as experts say, can effectively prevent covid-19 infection. In the United States, an international student who has received four injections was diagnosed with Anmi kerong infection shortly after, and although there has only been one case so far, it can be proved that the new crown vaccine does not completely avoid the infection of the mutant strain Aomi kerong. Nowadays, two or three injections can no longer guarantee the health of the people, and vaccination may be carried out every once in a while in the future.
summary
For many countries with high economic levels, they can be vaccinated by purchasing vaccines from other countries, or some countries with their own research and development technology can be self-sufficient, but for poor countries, the economic pressure of prolonged vaccination is completely unaffordable. At this point, people underestimated the harm of the new crown virus and overestimated the effectiveness of the vaccine. Many Western countries think that with their own high-end vaccine research and development technology, they can effectively curb the spread of the new crown virus, and now after the vaccine has begun to be injected, the daily new cases are still high, and the mutated virus has broken the vaccine defense system again and again, and the efficiency of the vaccine has been greatly reduced. The refusal of Western countries to step up the prevention and control of the epidemic is directly related to the universal values they have always formed, they have always believed that they can defeat all difficulties with powerful technology, and then the new crown virus is using bloody lessons to tell them how naïve their ideas are.
