Covid vaccine update: Dr Chris on the side effects to expect from second jab – 'fleeting'

The UK’s vaccination effort is operating at breakneck speed, thanks in part to the decision to administer only the first shot for now. Both the Oxford/AstraZeneca and Pfizer-BioNTech vaccines require a two-shot regimen to confer maximum resistance. Many questions abound, such as whether the side effects will differ with the second shot. Speaking on BBC News on Saturday, virologist Dr Chris Smith was quick to allay concerns, suggesting the side effects should be “fleeting” after the second shot.
