The new coronavirus mutates in the body and then transmittes to people or affects the effectiveness of the vaccine

BERLIN, Nov. 13 (Xinhua Peng Dawei) In response to a number of recent cases in Denmark of mutated new coronavirus transmission to humans, the European Center for Disease Control and Prevention (ECDC) said on the 12th, if the above-mentioned new coronavirus varieties in the population of large-scale transmission, may affect the overall effectiveness of the new crown vaccine under development. To this end, the Centre recommends targeted measures by EU countries and the UK to reduce public health risks.
The European Centre for Disease Control and Prevention (CDC) is located in Stockholm, Sweden, and is the EU's specialized agency for the prevention and control of infectious diseases.
5, 2020, Denmark reported 214 confirmed infections with new coronavirus variants associated with farmed ferns, while more than 200 farms were infected with farmed ferns, the CDC said in a statement released Tuesday. The earliest "breeding of ferns" incident dates back to April 2020, when an infection of a farmed fern and a farm worker was reported in the Netherlands.
the European Center for Disease Control and Prevention said that since then, it has been determined that the new coronavirus can be transmitted from person to person, can also be transmitted to humans by ferrets. Since then, countries such as Denmark, Italy, Spain, Sweden and the United States have also reported new coronavirus infections in their territories.
The Center emphasizes that when the new coronavirus is brought into a farm, it can spread rapidly among the herd, and due to factors such as large-scale infection and biological differences between humans and slugs, the new coronavirus may accumulate mutations in the herd more quickly and eventually spread to humans. Because the above variants of the new coronavirus have a lower susceptible to neutral antibodies, large-scale transmission in the population may affect the overall effectiveness of the new coronavirus currently under development. In addition, the formation of a "virus pool" in the herd may lead to more risky virus variants in the future.
In view of this, the European Centre for Disease Control and Prevention recommends that EU/EEA countries and the United Kingdom consider a number of targeted measures for farms, farm workers and surrounding communities, including population detection, antigen characteristics and viral infectious sequencing, and infection prevention and control measures for farm workers and visitors. At the same time, animals are tested to prevent animal transmission. Finally, a set of contingency plans and response strategies needs to be developed, taking into account both human and animal requirements.
