Brazil will provide Covid-19 vaccine booster shots to all its people over 60-years-old, Health Minister Marcelo Queiroga has said.

Queiroga said in a tweet that the decision comes in line with progress in the country's vaccination programme. About seven million Brazilians could get the booster shot under these conditions, he said.

Brazil had already started giving booster shots to people over 70-years-old and healthcare workers. According to Health Ministry data, about 600,000 booster shots have been administered up to now.
