Questions about second & booster doses


Why do I need the second and booster dose? 

The first dose of the vaccine offers good levels of protection, but to get maximum protection everyone must get a second dose, and then booster doses when invited to.

Fully vaccinated people are far less likely to get COVID symptoms, to get seriously ill with COVID-19, to be admitted to hospital, or to pass the virus onto others.


Does being fully vaccinated change the rules/restrictions?

Yes. People who have received two doses of COVID-19 vaccine no longer need to self-isolate if they are identified as a close contact of someone with COVID-19.


How soon after my first vaccination, will I get my second dose? 

In line with the latest guidance, the NHS is now offering second doses from 8 weeks after the first dose, instead of the 12 week period previously specified. 


How soon can I have a booster, after my second dose? 

You can pre-book a booster dose from 2 months (61 days) after your 2nd dose, but the appointment dates you'll be offered will be from 3 months (91 days) after your 2nd dose.


What about spring boosters?

You will also be offered an additional spring booster by the NHS if you:

  • are aged 75 and over
  • live in a care home for older people
  • are aged 12 and over and have a weakened immune system

You will usually be offered an appointment around 6 months after your last dose of COVID-19 vaccine.


What kind of vaccine will I get?

You cannot usually choose which vaccine you have - but when you book an appointment, you'll only be offered appointments for vaccines that are suitable for you.

The majority of booster vaccines now offered in Liverpool are Pfizer/BioNTech or Moderna vaccines because these are proven to be the most effective against current strains of covid-19.

This is unless there is a clinical reason why these are not suitable (in which case you may be offered Astra Zeneca or Moderna).


If I go to a different vaccine site for my second or booster doses, will the staff there know which vaccine I’ve already had? 

Yes. All vaccination sites have access to the same patient record system and they will ensure that you are given a second dose of the same vaccine you received for your first dose.
