The country has started administering booster shots of COVID-19 to health care and front line workers and senior citizens with comorbidities. In addition, about ten lakh 'precautionary' doses were given to 5.75 crore eligible people. The move is due to the sudden spike of the Omicron variant.
Various studies suggested that a booster dose could protect against the variant spread. According to a study in the UK, the booster dose could provide 88 percent protection against the Omicron variant. Prime Minister Narendra Modi has called it the 'precaution dose' wherein the same vaccine will be inoculated to a person who has already got two vaccines.
