Washington: The leader of the Trump administration’s vaccination program says people who have been infected with the coronavirus a group that includes President Donald Trump should receive the vaccine.

Moncef Slaoui, the chief adviser of Operation Warp Speed, told CNN’s ‘State of the Union’ that the vaccine is safe for those who have recovered and offers stronger and potentially longer protection than does the virus itself.

‘We know that infection doesn’t induce a very strong immune response and it wanes over time. So I think, as a clear precaution, it is appropriate to be vaccinated because it’s safe,’ he said. ‘I think people should be vaccinated, indeed.’

Trump is now one of the only senior-most US officials who has not received the first of two vaccination shots, which began being administered last week as part of the largest vaccination campaign in the nation’s history.

Vice President Mike Pence, House Speaker Nancy Pelosi, D-Calif, and Senate Majority Leader Mitch McConnell, R-Ky, all were given doses Friday. President-elect Joe Biden was to receive his Monday.

All have chosen to publicise their injections as part of a campaign to convince a skeptical public that the vaccines are safe and effective, in hopes of finally putting an end to a pandemic that has killed more than 317,000 people in the United States and upended life around the globe.

Trump, who in the past has spread misinformation about vaccine risks, tweeted earlier this month that he was ‘not scheduled’ to take the vaccine, but looked ‘forward to doing so at the appropriate time.’

The White House says he is still discussing timing with his doctors.

Trump was hospitalised with Covid-19 in October and given an experimental monoclonal antibody treatment that he credited for his swift recovery.
