PRESIDENTIAL Adviser for Entrepreneurship Jose Maria 'Joey' Concepcion 3rd on Thursday reiterated the need to make booster vaccination cards mandatory starting in June to encourage more people to get booster shots against Covid-19.

'We do not implement it right away. I understand it will take time for them to get the booster, but considering that vaccines are now more accessible, people are free to move around and we have adequate supply, I think two and a half months, or until June, would be enough time to take the boosters,' Concepcion said in a statement.
