The booster programme was sped up to stem Omicron cases, but what if you're one of the many who have Covid?
If you've recently had a positive Covid test, it could mean that your booster appointment date is up in the air.
All adults aged 18 and over were invited to book booster jabs from December 15 - but Omicron cases were spreading like wild fire.
That means those who had booster appointments might have had to cancel due to getting ill with the virus.
In fact, Nicola Sturgeon said on Tuesday that the biggest increase of cases (161 per cent) were within the 20 to 24-year-old age group.

When can you get booster after catching Covid?
The NHS says you should wait until four weeks after the date you were tested to get any dose of the vaccine - regardless of whether you have symptoms.
You can normally get a booster if three months have passed since your second dose.

Self-isolating means staying at home, not going to work, school or on public transit. You must not leave your home to buy food or essentials.
