Covid Vaccine – Booster Doses/Third Vaccine Explained

In News by John Geddes

BOOSTER DOSE

The effectiveness of vaccines tends to wear off with time, especially in older or very young people.

The Booster dose is for those who have had both doses of Covid vaccine at least 6 months ago. It will be offered to all over 50’s and to 16-49 year olds with underlying health conditions. 

Boosters will be given at least 6 months after the second vaccine. Roll out will be in the same order as the first vaccine 1-9 groups.

Boosters will be either Pfizer or Moderna, irrespective of which vaccine was given previously (unless there has been an allergic reaction to these vaccines before, in which case the Astra Zeneca will be given).

The “booster” Moderna dose, is half a normal dose. 
 

THIRD VACCINE

A Third vaccine will be offered to all those who are immune suppressed.

Third vaccines will be a full dose of either Pfizer or Moderna, irrespective of which vaccine was given previously (unless there has been an allergic reaction to these vaccines, then Astra Zeneca will be given). 

If you are eligible, you should receive a letter inviting you to have the third vaccine. This can be administered immediately as long as you have had at least 8 weeks since your second vaccine dose.

FLU VACCINE

All people with vasculitis are recommended to have the flu vaccine.  The influenza virus can be extremely dangerous for people who are immune suppressed or clinically extremely vulnerable.

Some professionals suggest that it would be better to have the flu and Covid vaccines on separate occasions – maybe a week or two apart. This is because if an allergic reaction should occur, the reaction would be reported for the vaccine involved. But this might be difficult for some GP practices due to the logistics. 

Some may receive two letters to receive both the booster and third vaccine especially if they are in the under-50 group or 19-49 group who have underlying health conditions. If this occurs, then please check with your own consultant which vaccine is appropriate for you.

Third vaccines must also be carefully timed for those receiving Rituximab or other biologics.  It important to check with your own consultant when/if you should have the vaccine. 

The above advice (and timings) are for England – if we receive any different advice for Scotland, NI or Wales, we will post a separate news item.
