countries need COVID-19 vaccines 2022
Vaccine Vaccination A group of UCL-based scientists has developed a scoring system to determine which countries require COVID-19 vaccines the most. The new technique, which is described as ‘transparent’ by the researchers, has been developed in an effort to ascertain which countries are in need of COVID-19 vaccines. The tool, which examines a broad range of variables, has been developed because the current COVAX procedure has been criticized by a range of nations for its lack of accessibility and its inability to change in accordance with local increases in infection.
The researchers asked 28 experts from 13 countries what they thought were the most significant variables for determining which countries required vaccines.
The expert group, composed of individuals based at universities and national public health institutes in the UK, Japan, Kenya, Norway, and South Africa, considered the proportion of the overall population that was not fully vaccinated to be the most important consideration when deciding where vaccines were needed.
Some other critical variables were the proportion of people at high risk who were not immunized, health care infrastructure, vaccine purchasing ability, and the proportion of people who were medically vulnerable.
A scoring system was then developed based on these variables in order to determine how much each should be weighted.
Using the tool, it is hoped that the process of allocating COVID-19 vaccines across the world will be fairer—by being explicit about the criteria used to identify needs and by being transparent about how the factors were identified and the evidence-based process used to derive the tool. In addition, the tool will be able to provide important information for future international discussions on how to address future public health emergencies.

According to Vageesh Jain (UCL Institute for Global Health), the equitable global distribution of COVID-19 vaccines has been a hot topic in global health, but so far there has been no clear definition of ‘vaccine equity.’
He goes on to say that ‘an equitable allocation of vaccines has gained significant attention, with limited attention paid to the assessment of resource prioritization across countries and the establishment of comparable levels of access.’ This is necessary in order to understand vaccine equity.
The current vaccination allocation method, COVAX, aims to provide enough vaccines to vaccinate 20% of each country’s population. It weighs a few variables (such as susceptibility to serious illness) and makes an qualitative evaluation.
Unfortunately, COVAX has not been able to provide vaccines to all those in need of them, and this has been exacerbated by the introduction of the Omicron variant, which resulted in high-income countries initially providing more booster shots than all vaccine shots in low-income countries.
According to Dr. Jain, the “current approach for allocating limited vaccines across countries, which was hastily developed during a global health crisis, warrants further study and, if possible, improvement.”
“The wide but variable repercussions of epidemics across populations and the variety of social value convictions make it difficult to assess the needs for COVID-19 vaccines.” However, our research has revealed that several factors outside of traditional measurements may cause some countries to have a greater need for vaccines than others.”
The most important factors for vaccine needs were the most frequent percentages of the overall population and high-risk populations who had not been vaccinated. Other factors, such as the economic repercussions of shutdowns, which are not typically considered in global vaccine allocation mechanisms, were also deemed vital.
We may see a similar scenario with monkeypox vaccine and vaccine equity, with vaccines being critical to outbreak containment. However, we have already observed wealthy nations purchasing up most of the vaccines, leaving a general shortage of supply for the remainder of the world. This transparent scoring tool will assist in quantitative assessments in order to advance the role of equity in global vaccine allocation.
