According to the World Health Organization, at least 70 potential vaccines against coronavirus are currently being developed, with 3 of them already undergoing clinical trials. WHO has published an updated list of vaccination activities. It presents all the activities that can stop the spread of the disease. The virus continues to spread. Currently, two million people are infected with it on the planet.
Among the deaths from coronavirus 110 thousand people. Scientists around the world are striving to create a vaccine that can stop a dangerous disease. Various organizations take part in creating the vaccine, including large pharmaceutical companies and small biotechnology firms, academic centres and non-profit medical associations.
Developing a new vaccine is a time-consuming, expensive, complex and time-consuming process. Traditionally, it takes hundreds of millions of dollars and several years of testing to get a safe and effective vaccine. The current pandemic is the third outbreak of coronavirus infection. The first outbreaks were associated with the SARS and MERS viruses.
But to this day, there are no approved vaccines against these coronavirus infections. Today, manufacturers hope to significantly reduce vaccine production time due to the seriousness of the situation. In China, CanSino biotechnology company is in the second phase of testing a potential vaccine. Testing is carried out on people.
Large corporations, such as Johnson-Johnson and Sanofi, also announce the rapid development of an effective vaccine. According to Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases of the United States, scientists will need another 12-18 months to approve the vaccine and verify its safety.
Otherwise, it can have tragic consequences. Scientists consider the vaccine development forecast for a year and a half optimistic. But all prospective vaccine candidates must pass a series of mandatory tests - on animals, on people, to confirm efficacy and safety.
Experts are concerned that any of them may lead to a risk of destruction of immunity because the essence of the vaccine is to weaken the immune system in the first stages to respond to the virus.
Reuters Peter Hottez, Dean of the National School of Tropical Medicine at Baylor College of Medicine, believes that every developer of the COVID-19 vaccine risks his reputation and the health of millions of people who might not be helped by the vaccine. Preliminary animal tests must go through all stages of identifying the effectiveness of the drug and confirming its safety.
