The People’s Vaccine Alliance (PVA), a group of organizations including Amnesty International, Oxfam, and the Joint United Nations Programme on HIV/AIDS, surveyed 77 medical experts in 28 countries worldwide and found that 2 out of 3 of them believe that a new Wuhan pneumonia (novel coronavirus disease, COVID-19) vaccine is needed within one year, while 1 out of 3 believes that the Time frame is less than 9 months. ) vaccine within 1 year, and 1 in 3 shortened the time to less than 9 months.
According to The Guardian, the epidemiologists, virologists and infectious disease experts, who come from Johns Hopkins University, Yale University, Imperial College London, the London School of Hygiene and Tropical Medicine and the University of Edinburgh, believe that vaccine coverage in many countries or regions around the world is quite low, making it more likely that the virus will develop drug-resistant mutations.
Gregg Gonsalves, associate professor of epidemiology at Yale University, revealed that new mutations occur every day, so the virus may find the most favorable pattern, not only to be able to spread more widely but also to get rid of the immune response that previous strains of the virus would lose.
Gonsalves emphasized that unless the world is vaccinated, the virus will always leave room for mutations, resulting in new variants that only a new vaccine can handle. Although the current Pfizer and Modena vaccines use messenger ribonucleic acid (mRNA), which can be adjusted more quickly to deal with mutations, issues of price and preservation have always prevented mass injections in poor countries.
In advanced countries such as the United Kingdom and the United States, hundreds of millions of doses of vaccine have been supplied and more than a quarter of the population has received at least one dose of the vaccine, but South Africa and Thailand have not been able to vaccinate even 1% of their populations, and some countries have not even promoted vaccination. In response, the Global Vaccine Access Mechanism (COVAX) has committed to provide vaccines to at least 27% of the population in low-income countries this year.
