One vaccine will not be enough
It is unlikely that a vaccine will bring the end of COVID. Some scientists are advising that we will likely need regular vaccinations.

Scientists are urging people not to treat a COVID-19 vaccine as “a silver bullet” to end the pandemic and return life to normal. Kate Bingham, the Chair of the UK Vaccine Taskforce, has issued warnings on this matter. She says the aim of the vaccine is to protect people from infection but that it was unlikely this would be effective for everyone. Furthermore, many researchers suggest we may see different strains of COVID-19 over the years. It is very unlikely that one vaccine will be enough. Bingham believes it is more probable that we will need regular revaccination to combat the virus. Studies looking into the mutations found in COVID-19 have so far found little evidence of mutation. Despite this, the increasing cases in many countries leave this to chance and scientists warn that each new case is a dice roll. A vaccine will doubtlessly be a good first step. But we all need to do more to ensure a smooth transition out of the pandemic.
The first vaccine will buy us more time to continue to research the virus and its possible mutations. Studies so far have not found a significant level of mutation in its virulence. This doesn’t mean it is impossible. But if this continues to be the case, perhaps one vaccine could be enough to help us overcome this pandemic.
