All patients receiving a Covid-19 Booster vaccination in Sirona Medical will receive either the Moderna vaccine or the Pfizer BioNTech vaccine. Both of these are mRNA vaccines which have been internationally recommended as Booster vaccines. They are both highly effective in reducing severe disease, hospitalisation and death from Covid-19.

There is no choice of vaccine as the vaccine supply is decided by the HSE and vaccine availability and we must administer in line with the HSE criteria.

Please read the booster vaccine information leaflets here before you attend.




  • In most cases, you should get a second Covid-19 booster dose 4 months (120 days) after your previous Covid-19 Booster vaccine dose. (If you are receiving a first Covid Booster, you must be 3 months or more since your second dose vaccine: see HSE information here.)


  • If you have had confirmed Covid-19 infection in the past 4 months (120 days), please do not book an appointment as a Booster is not advised for you at this time. (Three months or more since Covid infection if this is your first Covid booster: see HSE information here.)



  • Please arrive at the time of your appointment and no earlier/later – we will run as closely as possible to appointment times while adhering to public health guidelines. If we are running ahead or behind, we will do our best to contact you accordingly. Please be mindful of weather conditions as you will be waiting outside before being called for your vaccination.


  • There will be very limited or no parking available during these Covid-19 Booster clinics due to the high numbers of patients attending. You may be waiting outside for a few minutes before your vaccine so please wear warm clothing, suitable for the weather.


  • Please wear a short sleeve under your warm coat/jacket and clothing that allows easy access to your shoulder.


  • The doctor / nurse will ask you some questions to confirm your suitability to receive the vaccine. Please click the link above and read the information leaflet before your appointment.


  • The vaccine is given into your upper arm (similar to the flu vaccine). There is no longer a requirement for a 15 minute wait after your vaccination, unless you have had a previous reaction. If you have a history of anaphylaxis for any cause, you will be asked to remain on site for 30 minutes following the vaccine.


  • This is a vaccine appointment only – we will not be in a position to discuss any other medical issues with you and you will need to telephone for an appointment if you wish to see the doctor for any medical issue. We have to keep to a strict schedule to adhere to public health guidelines.


Please read the vaccine information using the links above before you attend. Some people will experience some side effects in the 48 hours after the vaccine, including sore arm, fever, headaches and generalized aches and pains. These can be treated with paracetamol and should resolve within 2-3 days.

Please note a fever following vaccination is a common expected side effect but if you experience a fever/high temperature lasting more than 48 hours and/or any symptoms of COVID (cough/ shortness of breath / chest tightness / loss of smell or taste) please contact the practice.

If you have a history of anaphylaxis to any vaccine you should let us know. If you think you may be allergic to any component of the Moderna or Pfizer BioNTech Comirnaty vaccine, please let us know, as you may not be eligible for the vaccine. Please contact the practice to discuss this if you have concerns around vaccine allergy.

Please ensure you continue to adhere to public health guidance regarding cough etiquette, social distancing and hand washing following your vaccination. If you develop ANY symptoms of head-cold / flu / sinus / respiratory infection, please contact the practice and we will postpone your appointment until your symptoms are fully cleared.

The Covid-19 vaccination programme, including the Boosters has a significant impact on the availability of appointments for all other general and regular consultations. It is however, a very important part of our national and community response to Covid-19 and is vital to provide additional protection for all patients against severe Covid-19 disease, hospitalisation and death.

We are very grateful for the patience and understanding of all our patients during the continued rollout of this complex COVID-19 vaccination programme.
