COVID-19 vaccines aim to reduce the number of individuals who get infected with moderate to severe COVID. And there is strong evidence that vaccines can do this, even for the dreaded delta plus variant.
Another issue is equity in terms of the distribution of vaccines. According to Our World in Data, an estimated 47.2% of the world’s population has received at least one dose of a COVID-19 vaccine. But only 2.8% of people from low-income countries are included in this proportion of vaccinated individuals.
While the debate in rich countries is whether booster shots are needed for the delta plus variant, those in poor countries are still waiting to acquire vaccines.
Low- and middle-income countries are trying to raise the numbers of the vaccinated despite limited resources. Deaths from COVID mostly come from high-risk groups such as the elderly and persons with comorbidities, so these countries have been prioritizing vaccines for those populations. But the majority of persons with no movement and travel restrictions are in the middle age, so it is important for these countries to be able to expand vaccination efforts to include them as well.
Key Takeaways
Overall, the benefits of getting the vaccines still outweigh the risks. It can protect against severe infection, hospitalization, and death.
