Covid-19 vaccines free from India next week, President Gotabaya Rajapaksa said on Saturday, a day after the country approved emergency use of Oxford AstraZeneca's Covishield vaccine."We do not have to wait longer than the 27th of this month to receive a quantity of free vaccines from India," the president said, addressing the presidential mobile service at Walallawita south of here this morning.Front-line health workers, the Army and the police and the most vulnerable elderly will be given the vaccine as a priority, the president said, amid warnings from doctors that front-line health workers should be quickly inoculated to prevent the medical system from collapsing."We will also buy Covid-19 vaccines from Russia and China," the president.
