For moderately to severely immunocompromised individuals: A 3rd primary series dose may be given ≥4 weeks (at least 28 days) after the 2nd dose. ≥12 years Same as adult dose. Dosage recommendations and approval may vary among countries. Refer to specific country guidelines.
Elderly: Same as adult dose.
Reconstitution
Before dilution, verify that the correct vial and method of preparation is selected. Thaw vials prior to dilution in the refrigerator between 2-8°C; for immediate use, thaw for 30 minutes at room temperature between 25-30°C and dilute within 2 hours. Vial must reach room temperature before dilution. Before dilution gently invert the vial 10 times, do not shake. Vial with purple cap: Add 1.8 mL of preservative-free 0.9% NaCl into the vial. Vial with orange cap: Add 1.3 mL of preservative-free 0.9% NaCl into the vial. Equalise vial pressure by withdrawing 1.8 or 1.3 mL of air into the empty diluent syringe before removing the needle from the vial respectively. Gently invert 10 times to mix, do not shake. Vial with grey cap must not be diluted. It is recommended to use a low dead-volume syringe and needle to withdraw the dose for administration.
Incompatibility
Incompatible with bacteriostatic 0.9% NaCl.
Contraindications
History of hypersensitivity following first dose or immediate allergic reaction (of any severity, occurring within 4 hours of administration) to any component of the formulation (e.g. polyethylene glycol [PEG]).
Special Precautions
Patient with bleeding disorders (e.g. thrombocytopenia, haemophilia); history of any immediate allergic reaction to any other vaccine or injectable therapy; autoimmune conditions. Immunocompromised patients. Patients who have received dermal fillers. Defer vaccination in patients with moderate to severe acute febrile illness (with or without fever); known current SARS-CoV-2 infection or exposure, patient who develop SARS-CoV-2 infection before receiving any vaccine dose, or after the first dose but before the 2nd dose, until recovery from acute illness (if symptomatic) and/or no longer requires isolation; those who have received COVID-19 convalescent plasma or anti-COVID-19 monoclonal antibody therapy (for at least 90 days). Defer vaccination in children or adults with history of multisystem inflammatory syndrome until resolution of illness or for ≥90 days after diagnosis. Defer 2nd dose in patients who experience myocarditis/pericarditis after the 1st dose; if 2nd dose is desired and is clinically appropriate, wait until complete resolution of signs/symptoms; those with history of myocarditis/pericarditis unrelated to mRNA COVID-19 vaccine may receive vaccination upon complete resolution of signs/symptoms. Not recommended for outbreak management or postexposure prophylaxis. Pregnancy and lactation; use only if potential benefits justify potential risks as there is limited data regarding the use of COVID-19 vaccines in pregnant and lactating women.

It should be noted that:

- Tozinameran may be available as a formulation under an FDA approved brand or as formulations under an emergency use listing or authorisation in some countries. Registration status and or availability may vary between countries.
- The safety and efficacy of tozinameran for immunisation against COVID-19 continue to be evaluated, preliminary data suggest a high vaccine efficacy in preventing COVID-19 following a complete course of vaccination.
- The duration of protection against COVID-19 after a complete vaccination course has not been fully evaluated. Clinical trials and epidemiologic surveillance are ongoing to evaluate break-through infection in fully vaccinated individuals.
- COVID-19 vaccines are not interchangeable. It is recommended to use the same brand of vaccine for both doses to complete the series. There are no data available on the interchangeability of COVID-19 vaccines, guidelines may vary among countries.
- For traceability of biological medicinal products, the name of the vaccine, batch, or lot number of the administered product must be properly recorded (refer to specific country guidelines).
- Tozinameran is supplied in multiple formulations and vial presentations; the method of preparation, requirements for dilution, dose volume, and storage requirements may differ between formulations. Refer to individual product guideline.
- The FDA approved formulation of tozinameran and the formulations under the emergency use authorisation for individuals ≥12 years may be used interchangeably.
- Due to the potential of vaccine administration errors (e.g. dosing errors), ensure that the correct age-appropriate formulation is selected for administration. Vials with purple or grey caps should not be used for individuals 5-11 years and vials with orange cap should not be used for individuals ≥12 years.
- Recommendations and approval for booster doses may vary among countries. Refer to specific country guidelines.
- It is recommended to give a booster dose for persons who are moderately to severely immunocompromised (for a total of 4 doses), particularly ≥3 months after the 2nd dose.
- To potentially decrease the small risk for myocarditis while possibly increasing the peak antibody responses and vaccine efficacy, a longer interval between the 1st and 2nd dose (8 weeks) may be optimal for certain populations ≥12 years, particularly males 12-39 years.
- Administration of antipyretics, antihistamines, aspirin or anticoagulants prior to the administration of COVID-19 vaccines for the purpose of preventing post-vaccination symptoms is not recommended. However, antipyretic/analgesic medications may be taken after vaccination to treat post-vaccination symptoms such as local pain or fever.
- Minimise any unnecessary co-medication whenever possible, given the lack of information about interaction risk.
- A person is considered fully vaccinated after receipt of the 2nd dose of the primary series. Recommendations and approval may vary among countries. Refer to specific country guidelines.
- Refer to your local health authority for the most up-to-date fact sheet when prescribing or administering tozinameran.
- To alleviate the risks of this unapproved drug during pandemic use, local regulatory agencies may require healthcare facilities and healthcare providers to comply with certain regulations for administration of tozinameran. Please refer to respective local regulatory agencies for further information.
Adverse Reactions
Significant: Syncope, hypersensitivity (e.g. anaphylaxis), contralateral or ipsilateral lymphadenopathy, Bell’s palsy; temporary swelling at or near the site of filler injection. Rarely, myocarditis and pericarditis (particularly in young males).
Gastrointestinal disorders: Nausea, vomiting, diarrhoea.
General disorders and administration site conditions: Inj site pain, swelling, redness; malaise, fatigue, chills, fever.
Musculoskeletal and connective tissue disorders: Muscle pain, joint pain, arthralgia, myalgia.
Nervous system disorders: Headache.
Skin and subcutaneous tissue disorders: Rash, pruritus, urticaria.
Patient Counseling Information
Fully vaccinated individuals (including those who have received a 3rd primary dose or booster dose) should continue to observe effective prevention measures (e.g. hand hygiene, wearing a mask, social distancing), please refer to your local health authorities.
Monitoring Parameters
Monitor for hypersensitivity reactions and syncope for 15 minutes after administration. Observe patients for 30 minutes for those with history of anaphylaxis due to any cause or an allergic reaction of any severity, within 4 hours after administration of a vaccine or injectable therapy; or a person with a contraindication to a different type of COVID-19 vaccine. Assess for signs and symptoms of myocarditis or pericarditis (e.g. acute and persisting chest pain, palpitations, shortness of breath).
Drug Interactions
Diminished therapeutic effect with COVID-19 directed monoclonal antibodies, derma fillers, and immunosuppressants. Antihistamines may mask the symptoms of anaphylaxis caused by COVID-19 vaccine (mRNA) which could lead to delay in diagnosis and management.
Action
Description: Tozinameran is an investigational COVID-19 vaccine that contains messenger RNA (mRNA) encoding the viral spike glycoprotein (S) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The nucleoside-modified mRNA is encapsulated in lipid nanoparticles, that enable delivery of the RNA into host cells, to direct transient expression of the SARS-CoV-2 spike (S) antigen. It contributes to the protection against COVID-19 by allowing both neutralising antibody and cellular immune responses to the S antigen.
Synonym: vaccine, COVID-19 mRNA (BNT162b2).
Onset: Virus neutralising antibody activity: 7-14 days after the 2nd dose.
