Although India shall start administering precautionary doses from January 10, Germany, UK and Israel are considering a fourth shot for their vulnerable population.
Moreover, analysis of booster shot administration from Our World in Data indicates that most other countries are way ahead of India in administering booster doses. The UK, for instance, has administered 47.6 doses per 100 people, Bahrain has administered 46.8 doses per 100 people, and Israel has administered 45.3. Brazil has covered 11.8 per cent of the population, whereas Russia has covered 4.7 per cent.
Sri Lanka has administered 15.8 booster doses per 100 people. There is a rich-poor divide in the administration of booster doses. High-income countries have administered 22.8 booster doses per 100 people, whereas upper-middle-income countries have covered 8.13 doses per 100 people. The coverage in low-middle-income countries was even lower at 0.47 per cent.
