Being double vaccinated offers the best protection against the Delta variant, first identified in India and now dominant in the UK, according to a new study.
But people who have had both doses can still catch and transmit the disease, so researchers say it is essential that as many people are possible get the jab.
Everyone aged 16 and over in the UK can now receive the Covid vaccine, and a third jab is expected to be rolled out for the most vulnerable from September.

Who's being vaccinated at the moment?
The JCVI - the scientific body advising the government on vaccines - says one dose of the Covid vaccine should be offered to everyone aged 16 and over. At the moment, 16-17-year olds are not expected to be offered a second dose.
The vaccine has already been approved for over-12s with underlying conditions or those who live with others at high risk, but there are no plans to give it routinely to this age group.
An estimated 89% of adults in the UK have now had at least one Covid jab, and around 77% of adults have had both doses, but many people under 30 are yet to receive theirs.
How do I get a vaccine?
In England adults and those within three months of turning 18 can book a jab either online or by calling 119. You can also visit a walk-in clinic without an appointment. Check your local health providers and social media groups for details.
All 16 and 17-year-olds are being invited by text or letter to make an appointment through their GP, or they may be able to go to a walk-in centre in their area.
In Scotland, everyone aged 16 and over can register to get the vaccine on the NHS inform website or by calling 0800 030 8013. Most health boards also have drop-in vaccination clinics.
