The benefit isn't only to a single recipient of the vaccine. It's to everyone. It reduces the spread via the immunised population to everyone else.
Nice to get confirmation from the scientific people.

"The results of the study, which has not yet been formally published, suggest that the vaccine may have a "substantial" effect on transmission of the virus.
It means the jab could have a greater impact on the pandemic, as each person who is vaccinated will indirectly protect other people too.
Mr Hancock called the study "really encouraging" on Twitter, adding that the results were "absolutely superb".
"Vaccines are the way out of this pandemic and we are making fantastic progress vaccinating the most vulnerable," he said.
The study by the University of Oxford, where the vaccine was developed, measured the impact on transmission by testing for asymptomatic infections, swabbing participants every week in addition to recording when anyone fell ill with Covid-19.
As well as showing an effect on transmission, the study found the vaccine offered 76% effective protection from a single dose for three months.
With no fall in protection during the three-month period, the researchers said the results supported gaps between first and second doses of between four and 12 weeks. The effectiveness of the vaccine increased with a longer gap of 12 weeks before the booster jab.
When the second dose is given, the study found the level of protection from the Oxford-AstraZeneca vaccine rises to 82%."
