Wasn't there already a shot being made a long time ago but was shut down due to a whole lot of hot air from critics and anti-vaxxers?
They claimed that the vaccine gave them Lyme when really the vaccine gave them an immune response for a few days... as vaccines should. Through a huge amount of media attention they scared away the pharma company, they stopped marketing, sales tanked, the vax was pulled. No medical issues with the vaccine were ever discovered.
If you read closely they attribute this to medical objections without mentioning the reason you're stating. Your statement better aligns with my memory of the period.
