Hello, this is Warren Murray with your trusted first read of the day.
Boris Johnson is to confirm the start of a booster jabs programme for the over-50s, while government scientists have approved vaccinations for older schoolchildren. In an address this afternoon, the prime minister is expected to signal his opposition to any further outright lockdowns this year, while keeping measures such as mask-wearing and social distancing in reserve.
The go-ahead on jabs for children aged 12 to 15 has teaching unions warning that schools are being put in an “invidious” position. They have called on ministers to confirm the programme will be overseen by specialists so teachers do not become caught up in issues of consent or anger from anti-vaccination groups.
