187 million cases of COVID-19, including more than 4 million deaths, worldwide. The same data show that health authorities have administered over 3 billion COVID-19 vaccine doses so far.
These vaccines have largely been allocated based on people’s susceptibility to contracting the virus and the risk of severe illness.
Several studies have shown that adverse outcomes from COVID-19 are linked to underlying health conditions, including cardiovascular disease, kidney disease, obesity, diabetes, and chronic obstructive pulmonary disease (COPD).
Other studies have found that socioeconomic factors, such as race and ethnicity and income influence COVID-19 case numbers. Vaccines for COVID-19 are predicted to be in short supply for the near future..
