Dr Laura Mount and Dr Dan Bunstone return to answer your coronavirus vaccination questions WE are getting to the stage where those who have already received their first coronavirus vaccines are due to receive their second. The second dose acts as a ‘booster’ jab to enhance immunity to the virus and offer a greater protection against infection. Many in this situation will have questions, including whether you have to go to the same location as before and when your appointment will be. To help, Dr Dan Bunstone and Dr Laura Mount, respective clinical directors of the Halliwell Jones Stadium and Orford Jubilee Hub vaccination centres, return to answer your questions.
