Despite the multiple efforts of different governments to vaccinate populations, the World Health Organization announces that herd immunity will not be achieved in 2021. This was reported by the WHO chief scientist, Dr. Soumya Swaminathan, at a press conference in which she asked to continue with hygiene and social distancing measures, in addition to the use of a mask.
Nowadays, more than 30 countries started vaccination campaigns. However, specialists said that this process will take quite a long time as billions of doses are needed. The productions and logistics around the vaccines are not as fast as many people think. It needs some time.
Herd immunity consists of vaccinating a sufficiently large proportion of individuals to become immune against a disease - in this case, Covid-19 - and thus make fewer individuals susceptible to contracting an infection. Immunity can be acquired by a vaccine or by contracting the disease naturally.
China said a WHO team of specialists would arrive in the country on Thursday. However, it was not specified if its experts would travel to Wuhan where human cases of COVID-19 were first detected in 2019. Nowadays, the situation in Wuhan seems to be controlled and better than in the rest of the world.
More than 90 million people have been diagnosed with the virus during the past year and many countries are now in the grip of escalating outbreaks. Nearly two million people have died.
