India to vaccinate elderly population from March 1. Which other countries have vaccinated senior citizens

India -- India, like many countries, has now shifted its focus from vaccinating only healthcare and frontline workers against the coronavirus disease (Covid-19) to senior citizens as they are more vulnerable to the virus. The vaccination programme for people above the age of 60 years and within the age bracket of 45-59 years with co-morbidities will begin from March 1 in the country. Over 239.6 million Covid-19 vaccine doses have been administered all over the world as of Saturday, according to the data compiled at the University of Oxford under 'REPLACED' project.
